The design of VNDocumentCameraViewController has been updated with iOS 26. Now the 'done' button that appears when at least one page has been scanned is by default in blue (liquid glass).
Changing the navBar or the barButtonItems tintColor does not work.
So, how does one change the color of this button to match the app's color?
Thank you very much!
You cannot change the color of the Done button in VNDocumentCameraViewController. Apple does not provide any API for customizing this system UI.
If you need full control over button colors or navigation appearance, you’ll need to build a custom scanning interface on top of Vision/AVFoundation instead of relying on the built-in document camera.
