Description
We observed multiple UI issues in VisionKit (VNDocumentCameraViewController) on iPad devices running iPadOS 26 (from Public Beta 4 onwards):
Tab bar button titles are not properly visible due to color/contrast issues.
An extra back button appears in the navigation bar when editing a captured image in landscape mode.
These issues seem to be iPadOS 26 bugs, as Apple does not provide public APIs to customize or override VNDocumentCameraViewController. VisionKit relies on private ICDocCam* classes, which are not accessible for modification.
Steps to Reproduce
Open the app on an iPad running iPadOS 26 (Public Beta 4 or later).
Switch the device to landscape mode.
Launch document scanning using VNDocumentCameraViewController.
Capture a document and tap Keep Scan.
Go to the edit captured image screen.
Observed Behavior:
Tab bar button titles are not clearly visible (color/contrast issue).
An extra back button is displayed in the navigation bar.
