Nutrient iOS SDK 26.1 release notes
16 October 2025
Nutrient iOS SDK 26.1 is a small update with fixes for various issues. This follows on from our big release for iOS 26 last month. For a future release, we’re hard at work adding on-device AI Assistant using Foundation Models — more details below.
If you’re updating from a version before Nutrient iOS SDK 26, read our release notes for that version for details about compatibility with Xcode 26 and the new design in iOS 26.
Building on our iOS 26 design update, Nutrient iOS SDK 26.1 improves the search bar appearance when search is active in the annotation list, outline view, and document picker.
On-device AI Assistant (early preview)
When Apple announced Foundation Models at WWDC25, we immediately started exploring what we could build for PDF documents with this framework. During the WWDC week itself, we built a working proof of concept of an on-device version of our AI Assistant that could answer questions about PDF documents without sending any data off the device.
That said, Foundation Models currently has a limited context window, which makes handling multipage documents complex and challenging. We aim to create a practical AI assistant that can answer questions about large documents while keeping processing entirely on-device.
This feature is ambitious. An early preview is available for testing on our PDF Viewer app for iPad and iPhone on TestFlight(opens in a new tab). (Make sure you have version 2025.12 or later.) Let us know if you’re interested in this feature for your app. We’d really appreciate your feedback.
Migration notes
This release removes convenience methods for converting NSValue to and from CGPoint and CGRect. If your code uses these methods, implement your own conversion helpers instead.
