--- title: "PSPDFKit 9.3 Migration Guide" canonical_url: "https://www.nutrient.io/guides/ios/migration-guides/pspdfkit-9-3-migration-guide/" md_url: "https://www.nutrient.io/guides/ios/migration-guides/pspdfkit-9-3-migration-guide.md" last_updated: "2026-06-09T10:22:07.675Z" description: "Learn how to update your iOS or Mac Catalyst project to PSPDFKit 9.3, featuring enhanced document permissions and support for iOS 11, 12, and 13." --- This guide covers updating an iOS or Mac Catalyst project from PSPDFKit 9.2.2 for iOS to PSPDFKit 9.3 for iOS. We encourage you to update as soon as possible, in order to take advantage of future new features and fixes. PSPDFKit 9.3 for iOS fully supports iOS 11, 12, and 13. iOS 11 support will be removed later during the PSPDFKit 9 lifecycle. Xcode 11.4 or later is required to use this version of the SDK. Learn more in our [version support](https://www.nutrient.io/../../announcements/version-support) guide. ## Document Permissions A PDF document defines a set of permissions that enable/disable certain actions a user can take with the document. These permissions cover things like printing, annotation modification, and content extraction. Prior to this release, we could read and write user permissions on a PDF document, but most of them were ignored by the SDK. PSPDFKit 9.3 for iOS adds comprehensive support for all available [document permissions](https://www.nutrient.io/guides/ios/features/document-permissions.md) so that the relevant UI actions are enabled/disabled based on which permissions are available. The permissions are defined using the `DocumentPermissions` API (`PSPDFDocumentPermissions` in Objective-C). Here’s a brief list of the effects each permission has when disabled: - `.printing` — The `UIActivityTypePrint` activity will be removed from the available sharing activities when using the `DocumentSharingConfiguration.Destination.activity` sharing destination, and the `DocumentSharingConfiguration.Destination.print` sharing destination will not be available. - `.extract` — The user will not be able to copy selected text or images. - `.assemble` — The user will not be able to enter the Document Editor view mode. - `.annotationsAndForms` — The user will not be able to create new annotations; move, resize, or rotate existing annotations; or add comments to existing annotations. - `.fillForms` — If disabled along with `.annotationsAndForms`, the user will not be able to fill in form fields, including signature fields, checkboxes, and radio buttons. - `.modification` — The user will not be able to add or edit bookmarks, redact portions of a document, or edit information like a document’s title and author information. Make sure to read the [document permissions](https://www.nutrient.io/guides/ios/features/document-permissions.md) guide to learn more about this, including how to disable this behavior. ## Objective-C Changes > If you’re using the PSPDFKit SDK with Swift, jump to the [Swift-Only Changes](#swift-only-changes) section. - Changed: Presentation option constants for the `PSPDFPresentationActions` protocol have been deprecated in favor of renamed constants with the `PSPDFPresentationOption` prefix. This is for consistency and improved Swift interoperability. | Deprecated API | Replacement API | | ----------------------------------------------- | -------------------------------------------------- | | `PSPDFPresentationStyleKey` | `PSPDFPresentationOptionPresentationStyle` | | `PSPDFPresentationHalfModalStyleKey` | `PSPDFPresentationOptionHalfModalStyle` | | `PSPDFPresentationNonAdaptiveKey` | `PSPDFPresentationOptionNonAdaptive` | | `PSPDFPresentationRectBlockKey` | `PSPDFPresentationOptionSourceRectProvider` | | `PSPDFPresentationContentSizeKey` | `PSPDFPresentationOptionContentSize` | | `PSPDFPresentationInNavigationControllerKey` | `PSPDFPresentationOptionInNavigationController` | | `PSPDFPresentationReuseNavigationControllerKey` | `PSPDFPresentationOptionReuseNavigationController` | | `PSPDFPresentationPopoverArrowDirectionsKey` | `PSPDFPresentationOptionPopoverArrowDirections` | | `PSPDFPresentationPopoverPassthroughViewsKey` | `PSPDFPresentationOptionPopoverPassthroughViews` | | `PSPDFPresentationPopoverBackgroundColorKey` | `PSPDFPresentationOptionPopoverBackgroundColor` | | `PSPDFPresentationRectKey` | `PSPDFPresentationOptionSourceRect` | | `PSPDFPresentationCloseButtonKey` | `PSPDFPresentationOptionCloseButton` | | `PSPDFViewControllerSearchHeadlessKey` | `PSPDFPresentationOptionSearchHeadless` | - Changed: Similarly, the existing constants used to access the contents of the dictionary objects of `PSPDFGalleryItem` have been deprecated in favor of a new type, `PSPDFGalleryItemProperty`. | Deprecated API | Replacement API | | ------------------------------- | --------------------------------- | | `PSPDFGalleryItemTypeKey` | `PSPDFGalleryItemPropertyType` | | `PSPDFGalleryItemContentURLKey` | `PSPDFGalleryItemPropertyURL` | | `PSPDFGalleryItemCaptionKey` | `PSPDFGalleryItemPropertyCaption` | | `PSPDFGalleryItemOptionsKey` | `PSPDFGalleryItemPropertyOptions` | - Changed: The following cases from the `PSPDFFlexibleToolbarPosition` enum have been deprecated and replaced. | Deprecated API | Replacement API | | --------------------------------------- | -------------------------------------- | | `PSPDFFlexibleToolbarPositionsVertical` | `PSPDFFlexibleToolbarPositionVertical` | | `PSPDFFlexibleToolbarPositionsAll` | `PSPDFFlexibleToolbarPositionAll` | - Changed: The existing `PSPDFSettingKey` constants have been deprecated in favor of the new ones, which are more semantically named. | Deprecated API | Replacement API | | ---------------------------------- | ------------------------------------------ | | `PSPDFXCallbackURLStringKey` | `PSPDFSettingKeyXCallbackURLString` | | `PSPDFApplicationPolicyKey` | `PSPDFSettingKeyApplicationPolicy` | | `PSPDFFileManagerKey` | `PSPDFSettingKeyFileManager` | | `PSPDFCoordinatedFileManagerKey` | `PSPDFSettingKeyCoordinatedFileManager` | | `PSPDFFileCoordinationEnabledKey` | `PSPDFSettingKeyFileCoordinationEnabled` | | `PSPDFLibraryIndexingPriorityKey` | `PSPDFSettingKeyLibraryIndexingPriority` | | `PSPDFKitDebugModeKey` | `PSPDFSettingKeyDebugMode` | | `PSPDFAdditionalFontDirectories` | `PSPDFSettingKeyAdditionalFontDirectories` | | `PSPDFHonorDocumentPermissionsKey` | `PSPDFSettingKeyHonorDocumentPermissions` | - Changed: The existing `PSPDFAnnotationOption` constants have been deprecated in favor of the new ones, which are semantically named for improved Swift interoperability. | Deprecated API | Replacement API | | ----------------------------------------------- | -------------------------------------------- | | `PSPDFAnnotationOptionAnimateViewKey` | `PSPDFAnnotationOptionAnimateView` | | `PSPDFAnnotationOptionSuppressNotificationsKey` | `PSPDFAnnotationOptionSuppressNotifications` | - Changed: The `PSPDFRectAlignment` API cases have been renamed to provide better interoperability in Swift. | Previous API | New API | | --------------------------- | ------------------------------- | | `PSPDFRectAlignCenter` | `PSPDFRectAlignmentCenter` | | `PSPDFRectAlignTop` | `PSPDFRectAlignmentTop` | | `PSPDFRectAlignTopLeft` | `PSPDFRectAlignmentTopLeft` | | `PSPDFRectAlignTopRight` | `PSPDFRectAlignmentTopRight` | | `PSPDFRectAlignLeft` | `PSPDFRectAlignmentLeft` | | `PSPDFRectAlignBottom` | `PSPDFRectAlignmentBottom` | | `PSPDFRectAlignBottomLeft` | `PSPDFRectAlignmentBottomLeft` | | `PSPDFRectAlignBottomRight` | `PSPDFRectAlignmentBottomRight` | | `PSPDFRectAlignRight` | `PSPDFRectAlignmentRight` | - Changed: The `fields` property of `PSPDFAbstractFormAnnotation` is now typed `NSArray> *`, in order to more clearly document what this property contains. The newly introduced `PSPDFFormFieldIdentifier` protocol is a trait added to `NSString` and `NSNumber`. - Changed: `-[PSPDFFreeTextAnnotation convertToIntentType:]` has been deprecated. Use `-[PSPDFFreeTextAnnotation convertIntentTypeTo:]` instead. - Changed: `-[PSPDFSoundAnnotation initWithRecorder]` has been deprecated. Use `-[PSPDFSoundAnnotation initWithRecorderOptions:]` with a `nil` parameter for options instead. ## Swift-Only Changes > If you’re using the PSPDFKit SDK with Objective-C, check out the [Objective-C Changes](#objective-c-changes) section. The entire SDK has been carefully tweaked to make the entirety of our API semantic in Swift. We dropped the `PSPDF` prefix and tried to group related APIs by nesting them where appropriate and possible. Due to the vastness of the changes, and in order to keep the migration guide concise, we’ve only mentioned the API changes that could break your build and which cannot be fixed using Xcode’s suggestion (the Fix button). Most of the API changes can be reliably fixed using the Fix All Issues option (Control-Option-Command-F) in Xcode. This fixes all the issues in the currently opened file. Some of the files may require multiple iterations of using Xcode’s fix option, as some the errors will only be caught after the initially shown errors are fixed. - Changed: The `String` constants used in the `PSPDFPresentationActions` protocol have been removed in favor of the new Swift `struct` type, `PresentationOption`. All the places where the old constants are used as arguments will throw an error while compiling since the type of the method arguments has also been changed from `String` to the appropriate new struct type. | Previous API | New API | | ----------------------------------------------- | ---------------------------- | | `PSPDFPresentationStyleKey` | `.presentationStyle` | | `PSPDFPresentationHalfModalStyleKey` | `.halfModalStyle` | | `PSPDFPresentationNonAdaptiveKey` | `.nonAdaptive` | | `PSPDFPresentationRectBlockKey` | `.sourceRectProvider` | | `PSPDFPresentationContentSizeKey` | `.contentSize` | | `PSPDFPresentationInNavigationControllerKey` | `.inNavigationController` | | `PSPDFPresentationReuseNavigationControllerKey` | `.reuseNavigationController` | | `PSPDFPresentationPopoverArrowDirectionsKey` | `.popoverArrowDirections` | | `PSPDFPresentationPopoverPassthroughViewsKey` | `.popoverPassthroughViews` | | `PSPDFPresentationPopoverBackgroundColorKey` | `.popoverBackgroundColor` | | `PSPDFPresentationRectKey` | `.sourceRect` | | `PSPDFPresentationCloseButtonKey` | `.closeButton` | | `PSPDFViewControllerSearchHeadlessKey` | `.searchHeadless` | - Changed: The constants used for accessing the dictionary values of a `PSPDFGalleryItem` have been replaced with the `GalleryItem.Property` struct. | Previous API | New API | | ------------------------------- | ------------- | | `PSPDFGalleryItemTypeKey` | `.type` | | `PSPDFGalleryItemContentURLKey` | `.contentURL` | | `PSPDFGalleryItemCaptionKey` | `.caption` | | `PSPDFGalleryItemOptionsKey` | `.options` | If any of these types happen to clash with other declarations in Swift, this can be resolved by accessing the type using the module name. For example, use `PSPDFKitUI.GalleryItem.Option.autoPlay` instead of `GalleryItem.Option.autoPlay`. - Changed: The `PSPDFAnnotationOption` type has been renamed to `AnnotationManager.ChangeBehaviorKey` in Swift. Its existing values have been deprecated in favor of semantically named ones. | Deprecated API | New API | | ------------------- | ------------------------ | | `.animateViewKey` | `.animateView` | | `.notificationsKey` | `.suppressNotifications` | - Changed: The `PSPDFRectAlignment` enumeration has been renamed to `RectAlignment` for Swift. Its cases have also been renamed. | Previous API | New API | | ------------------- | -------------- | | `.alignCenter` | `.center` | | `.alignTop` | `.top` | | `.alignTopLeft` | `.topLeft` | | `.alignTopRight` | `.right` | | `.alignLeft` | `.left` | | `.alignBottom` | `.bottom` | | `.alignBottomLeft` | `.bottomLeft` | | `.alignBottomRight` | `.bottomRight` | | `.alignRight` | `.right` | - Changed: `PSPDFFlexibleToolbarPosition` has been updated with a new Swift name, `FlexibleToolbar.Position`. Some position values have been deprecated and replaced with new ones to ensure better translation to Swift names. | Previous API | New API | | -------------------- | ----------- | | `.positionNone` | `.none` | | `.positionInTopBar` | `.inTopBar` | | `.positionLeft` | `.left` | | `.positionRight` | `.right` | | `.positionsVertical` | `.vertical` | | `.positionsAll` | `.all` | - Changed: `PSPDFSettingKey` has been renamed to `SDK.Setting`, and the existing constants have been deprecated in favor of new ones, which are more semantically named. | Deprecated API | Replacement API | | ------------------------------ | ---------------------------- | | `.PSPDFXCallbackURLStringKey` | `.xCallbackURLString` | | `.applicationPolicyKey` | `.applicationPolicy` | | `.fileManagerKey` | `.fileManager` | | `.coordinatedFileManagerKey` | `.coordinatedFileManager` | | `.fileCoordinationEnabledKey` | `.fileCoordinationEnabled` | | `.libraryIndexingPriorityKey` | `.libraryIndexingPriority` | | `.debugModeKey` | `.debugMode` | | `.additionalFontDirectories` | `.additionalFontDirectories` | | `.honorDocumentPermissionsKey` | `.honorDocumentPermissions` | - Changed: `PSPDFMetadataName` has been renamed to `PDFMetadata.Key`, and the existing constants have been deprecated in favor of new ones, which are more semantically named. | Previous API | New API | | ------------------ | ------------------- | | `.titleKey` | `.title` | | `.authorKey` | `.author` | | `.subjectKey` | `.subject` | | `.keywordsKey` | `.keywords` | | `.creatorKey` | `.creator` | | `.producerKey` | `.producer` | | `.creationDateKey` | `.creationDate` | | `.modDateKey` | `.modificationDate` | | `.trappedKey` | `.trapped` | - Changed: `PSPDFValueTransformerName` has been renamed to `ValueTransformerName`, and the existing constants have been replaced. See below for the list. | Previous API | New API | | ------------------------------------------ | --------------------------- | | `.actionTypeTransformerName` | `.actionType` | | `.annotationTriggerEventTransformerName` | `.annotationTriggerEvent` | | `.borderEffectTransformerName` | `.borderEffect` | | `.borderStyleTransformerName` | `.borderStyle` | | `.freeTextAnnotationIntentTransformerName` | `.freeTextAnnotationIntent` | | `.namedActionTypeTransformerName` | `.namedActionType` | | `.polygonAnnotationIntentTransformerName` | `.polygonAnnotationIntent` | | `.renditionActionTypeTransformerName` | `.renditionActionType` | | `.verticalAlignmentTransformerName` | `.verticalAlignment` | - Changed: `PSPDFDocumentUnderlyingFileChangedNotificationOptions` has been renamed to `Document.UnderlyingFileChangedNotificationOption`, and the existing constants have been replaced. See below for the list. | Previous API | New API | | ------------------- | ----------------- | | `.urlKey` | `.changedFileURL` | | `.willBeDeletedKey` | `.deleteFile` | ## Annotation API Refinements - Changed: `AnnotationStyleType` has been renamed to `AnnotationStyle.Kind`. | Previous API | New API | | ------------------ | --------------- | | `.titleKey` | `.title` | | `.authorKey` | `.author` | | `.subjectKey` | `.subject` | | `.keywordsKey` | `.keywords` | | `.creatorKey` | `.creator` | | `.producerKey` | `.producer` | | `.creationDateKey` | `.creationDate` | - Changed: `AnnotationStyleKey` has been renamed to `AnnotationStyle.Key`. - Changed: `AnnotationString` has been renamed to `Annotation.Tool`. - Changed: `AnnotationVariantString` has been renamed to `Annotation.Variant`. - Changed: `AnnotationStateVariantID` has been renamed to `Annotation.ToolVariantID`. - Removed: The `PSPDFStringFromAnnotationType()` helper for creating `Annotation.Tool` from `Annotation.Kind` has been removed. Use the `init?(kind:)` initializer on `Annotation.Tool` instead. - Removed: The `PSPDFAnnotationTypeFromString()` helper for creating `Annotation.Kind` from `Annotation.Tool` has been removed. Use the `init(tool:)` initializer on `Annotation.Kind` instead. - Removed: The `PSPDFAnnotationStateVariantIDMake()` helper for generating `Annotation.ToolVariantID` has been removed. Use `Annotation.ToolVariantID(tool:, variant:)` instead. - Removed: The `PSPDFAnnotationStateFromStateVariantIdentifier()` helper for extracting `Annotation.Tool` has been removed. Use the `tool` property on `Annotation.ToolVariantID` instead. - Removed: The `PSPDFAnnotationVariantFromStateVariantIdentifier()` helper for extracting `Annotation.Variant` has been removed. Use the `variant` property on `Annotation.ToolVariantID` instead. - Changed: The type of the `Annotation.additionalActions` property has been changed to `[Annotation.TriggerEvent: Action]`. - Changed: The type of the `Annotation.dashArray` property has been changed to `[CGFloat]`. - Changed: The type of the `Annotation.rects` property has been changed to `[CGRect]`. - Changed: The type of the `Annotation.points` property has been changed to `[CGPoint]`. - Changed: The `AbstractFormAnnotation.fields` property has been renamed to `fieldIdentifiers` to more clearly document what this array contains. Its type has been changed from `[Any]?` to `[FormFieldIdentifier]?`, where the nested `enum FormFieldIdentifier` further documents the semantics. For coding convenience, the enum is both `ExpressibleByIntegerLiteral` and `ExpressibleByStringLiteral`. - Added: A new type, `PDFLine`, which is a type alias for an array of `DrawingPoint` (`[DrawingPoint]`), has been added. - Added: A new type, `ViewLine`, which is a type alias for an array of `CGPoint` (`[CGPoint]`), has been added. - Removed: `InkAnnotation(lines: [[NSValue]])` has been removed. Use `InkAnnotation(lines: [PDFLine])` instead. - Changed: The type of the `InkAnnotation.lines` property has been updated from `[[NSValue]]` to `[PDFLine]`). - Changed: The type of the `points` parameter in initializers of `AbstractLineAnnotation` (formerly `PSPDFAbstractLineAnnotation`) and `PolygonAnnotation` has been updated to an array of `CGPoint` instead of an array of `NSValue`. Updated APIs: `AbstractLineAnnotation(points: [CGPoint])`, `PolygonAnnotation(points: [CGPoint], intentType: PolygonAnnotation.Intent =.none)` - Removed: `FreeTextAnnotation.convert(toIntentType:)` has been deprecated. Use `FreeTextAnnotation.convertIntent(to:)` instead. - Changed: The `rects` parameter to `TextMarkupAnnotation`’s class method — `textOverlayAnnotation(withRects:,boundingBox:,pageIndex:)` — has been changed from `[NSValue]` to `[CGRect]`. The signature of this method is now `class func textOverlayAnnotation(withRects rects: [CGRect], boundingBox: CGRect, pageIndex: Int) -> Self?`. - Changed: The `PSPDFAnnotationAuthorState` and `PSPDFAnnotationAuthorStateModel` APIs have been consolidated into the `Annotation.State` API, which is an enum with associated values. Below is the list of the possible values for the `Annotation.State` type. The change above affects the `NoteAnnotation` API. Since the two types have been reorganized into a single type (`Annotation.State`), `NoteAnnotation` uses a single property (`authorState`) to show the author-specific state. This means that the other property, `authorStateModel`, has been removed. | Annotation.State | | ------------------------------------------ | | `.unspecified` | | `.marking(Annotation.State.MarkedModel)` | | `.reviewing(Annotation.State.ReviewModel)` | - Changed: `SoundAnnotation(recorderOptions:)` has been updated to take a parameter of type `Set` instead of a dictionary. `SoundAnnotation.RecorderOption` is an enum with associated values that can be used to configure a recorder. - Removed: The `SoundAnnotation.initWithRecorder()` API has been removed. Use `SoundAnnotation(recorderOptions:)` by passing an empty set as the `recorderOptions:` parameter instead. | SoundAnnotation.RecorderOption | | --------------------------------------------------------------- | | `.encoding(SoundAnnotation.Encoding)` | | `.channels(UInt32)` | | `.sampleRate(hertz: SoundAnnotation.RecorderOption.SampleRate)` | | `.bitsPerSample(SoundAnnotation.RecorderOption.Depth)` | ## Document API Refinements - Removed: The `save(options: [PSPDFDocumentSaveOption : Any]) throws` API on `Document` (formerly `PSPDFDocument`) has been removed. Use the `save(options: Set) throws` API instead. - Removed: The `save(options: [PSPDFDocumentSaveOption : Any]?, completionHandler: ((Error?, [PSPDFAnnotation]) -> Void)?)` API of `Document` has also been removed. Use `save(options: Set = [], completion: @escaping (Result<[Annotation], Error>) -> Void)` instead. ## Note Annotation Icon - Changed: The icon used for representing the note annotation tool in the annotation toolbar has been replaced. You can read more about how to customize the icon in our [customizing the annotation toolbar](https://www.nutrient.io/../../customizing-the-interface/customizing-the-annotation-toolbar/#annotation-buttons) guide. | Old | New | | ---------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------- | |![old-note-annotation-icon](@/assets/guides/ios/migration-guides/pspdfkit-9-3-migration-guide/old-note-icon.png) |![new-note-annotation-icon](@/assets/guides/ios/migration-guides/pspdfkit-9-3-migration-guide/new-note-icon.png) | ## Flexible Toolbar Position - Changed: The default value for [`FlexibleToolbarPosition`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/flexibletoolbar/position)’s [`supportedToolbarPositions`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/flexibletoolbar/supportedtoolbarpositions) property has changed from [`.all`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/flexibletoolbar/position/all) to [`.default`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/flexibletoolbar/position/default). If you were programmatically setting your toolbar’s [`supportedToolbarPositions`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/flexibletoolbar/supportedtoolbarpositions) to [`.all`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/flexibletoolbar/position/all), use [`.default`](https://www.nutrient.io/api/ios/documentation/pspdfkitui/flexibletoolbar/position/default) instead to support the default toolbar positions. For more details on how to customize the toolbar positions, take a look at both our [customizing the annotation toolbar](https://www.nutrient.io/../../customizing-the-interface/customizing-the-annotation-toolbar/) guide and [`ToolbarPositionTopExample.swift`](https://github.com/PSPDFKit/pspdfkit-ios-catalog/blob/master/Catalog/Examples/ControllerCustomization/ToolbarPositionTopExample.swift) from the [Catalog app](https://www.nutrient.io/guides/ios/getting-started/example-projects.md#nutrient-catalog). ## Class Overriding The class overriding mechanism is now more type-safe and better documented. All classes that can be overridden now conform to the [`Overridable`](https://www.nutrient.io/api/ios/documentation/pspdfkit/overridable) protocol. Classes that don’t conform to it are no longer accepted by `overrideClass(_:with:)` and can no longer participate in the mechanism. If you were overriding an illicit class, you might now see compile warnings or errors. If you were implementing the `Overridable` protocol in your own classes, remove the conformance. It will no longer work with the class overriding mechanism. --- ## Related pages - [Migrating From Apple Pdfkit](/guides/ios/migration-guides/migrating-from-apple-pdfkit.md) - [14 9 Migration Guide](/guides/ios/migration-guides/14-9-migration-guide.md) - [14 2 Migration Guide](/guides/ios/migration-guides/14-2-migration-guide.md) - [Migrating To Advanced Digital Signatures Api](/guides/ios/migration-guides/migrating-to-advanced-digital-signatures-api.md) - [Migrate to electronic signatures](/guides/ios/migration-guides/migrating-to-electronic-signatures.md) - [Pspdfkit 10 3 Migration Guide](/guides/ios/migration-guides/pspdfkit-10-3-migration-guide.md) - [Pspdfkit 10 4 Migration Guide](/guides/ios/migration-guides/pspdfkit-10-4-migration-guide.md) - [Pspdfkit 10 Migration Guide](/guides/ios/migration-guides/pspdfkit-10-migration-guide.md) - [Pspdfkit 11 3 Migration Guide](/guides/ios/migration-guides/pspdfkit-11-3-migration-guide.md) - [Pspdfkit 11 5 Migration Guide](/guides/ios/migration-guides/pspdfkit-11-5-migration-guide.md) - [Pspdfkit 12 2 Migration Guide](/guides/ios/migration-guides/pspdfkit-12-2-migration-guide.md) - [Pspdfkit 12 3 Migration Guide](/guides/ios/migration-guides/pspdfkit-12-3-migration-guide.md) - [Pspdfkit 13 3 Migration Guide](/guides/ios/migration-guides/pspdfkit-13-3-migration-guide.md) - [Pspdfkit 13 Migration Guide](/guides/ios/migration-guides/pspdfkit-13-migration-guide.md) - [Pspdfkit 12 Migration Guide](/guides/ios/migration-guides/pspdfkit-12-migration-guide.md) - [Pspdfkit 11 4 Migration Guide](/guides/ios/migration-guides/pspdfkit-11-4-migration-guide.md) - [Pspdfkit 3 Migration Guide](/guides/ios/migration-guides/pspdfkit-3-migration-guide.md) - [Pspdfkit 4 Migration Guide](/guides/ios/migration-guides/pspdfkit-4-migration-guide.md) - [Pspdfkit 5 Migration Guide](/guides/ios/migration-guides/pspdfkit-5-migration-guide.md) - [Pspdfkit 6 5 Migration Guide](/guides/ios/migration-guides/pspdfkit-6-5-migration-guide.md) - [Pspdfkit 6 Migration Guide](/guides/ios/migration-guides/pspdfkit-6-migration-guide.md) - [Pspdfkit 7 6 Migration Guide](/guides/ios/migration-guides/pspdfkit-7-6-migration-guide.md) - [Pspdfkit 9 2 Migration Guide](/guides/ios/migration-guides/pspdfkit-9-2-migration-guide.md) - [Pspdfkit 9 4 Migration Guide](/guides/ios/migration-guides/pspdfkit-9-4-migration-guide.md) - [Migrate to PSPDFKit 7 with ease](/guides/ios/migration-guides/pspdfkit-7-migration-guide.md) - [Upgrading](/guides/ios/getting-started/upgrading.md) - [Pspdfkit 9 5 Migration Guide](/guides/ios/migration-guides/pspdfkit-9-5-migration-guide.md) - [PSPDFKit 8 migration guide for iOS developers](/guides/ios/migration-guides/pspdfkit-8-migration-guide.md) - [Pspdfkit 9 Migration Guide](/guides/ios/migration-guides/pspdfkit-9-migration-guide.md)
