Nutrient iOS SDK 26.6 release notes

5 March 2026

Nutrient iOS SDK 26.6 adds an option to use Apple PencilKit for handwritten signatures, and it includes a broad set of reliability fixes across annotation workflows, text editing, search, and real-time collaboration. For the full list of changes, see our changelog.

Better handwritten signatures with PencilKit

You can now enable PencilKit for the Draw mode in SignatureCreationViewController by setting usePencilKit to true. This improves the look and feel of drawn signatures and gives users a signing experience that feels more at home on modern Apple platforms.

As part of this change, SignatureCreationViewController.drawView is deprecated, since that API doesn’t work with PencilKit-based signing. If you rely on drawView, please contact us so we can help you with a migration path.

Migration notes

This release includes changes you should account for when upgrading:

  • Nutrient iOS SDK now requires Xcode 26.3.
  • Copying an Annotation via NSCopying now produces a new uuid for the copied annotation.
