`UIView.LayoutRegion.safeArea(cornerAdaptation:)` was introduced in iOS 26 to provide correct insets for the new macOS-like system controls (iPad). On iOS 26.0 this API reports different values than on iOS 26.1+ and adds unexpected horizontal safe-area insets. To avoid content being shifted horizontally **on iPhone**, we fall back to the pre–iOS 26 behavior (using `view.safeAreaInsets`) on **non-pad idioms** when running on iOS 26.0. The same issue can also affect iPad on iOS 26.0, but there we intentionally keep using layout regions: adopting the new iPad controls is prioritized even if it means accepting the extra horizontal inset on iOS 26.0. Fixes [CMP-10046](https://youtrack.jetbrains.com/issue/CMP-10046) WindowInsets.systemBars add some arbitrary horizontal space on iOS but not on Android ## Testing This should be tested by QA ## Release Notes ### Fixes - iOS - _(prerelease fix)_ Fix `WindowInsets.systemBars` add extra horizontal insets on iOS 26.0
