An app with a UIToolbar pinned to the bottom of a view controllers view extends to the screen edge (behind the safe area) when run on iOS 18.X but not iOS 26.

This UIToolbar is set as constrained to the safeAreaLayoutGuide with the following constraints.

self.view.addConstraints([
            bottomToolbar.leadingAnchor.constraint(equalTo: self.view.leadingAnchor),
            bottomToolbar.trailingAnchor.constraint(equalTo: self.view.trailingAnchor),
            bottomToolbar.bottomAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.bottomAnchor),
            bottomToolbar.heightAnchor.constraint(greaterThanOrEqualToConstant: 44.0)
        ])

This is especially noticeable when the UIToolbar background color differs from the view background color.

This occurs on iOS 26 beta 6, app built with Xcode 26 beta 5.

I've posted a Feedback FB19664903 including a minimal Xcode workspace that reproduces this issue.

Anyone suggestions would be appreciated ... this definitely seems like a regression.

This is NOT corrected in Xcode 26 beta 6 / iOS 26 beta 7

These attached screenshots (from the simple Xcode workspace we submitted with FB19664903) show this issue, the first screenshot is from iOS 26 beta 7 (white gap below the red bottom toolbar), the second screenshot is the same code running on iOS 18.6 (red toolbar extends behind safe area).

We have an app that uses many of these bottom toolbars and I'd prefer not to have to refactor....I'm surprised this hasn't received more "me toos"

We're working around this by creating a custom UIView for bottom toolbar that contains an embedded UIToolbar. The UIView constrained to superview .bottom, and UIToolbar constrained to UIView safeAreaLayoutGuide.bottom
