Mon, 30 Jun 2025 22:45:37 GMT https://developer.apple.com/forums/thread/800382 Hello, I'm experiencing a navigation bar positioning issue with my UIKit iPad app on iPadOS 26 (23A340) using Xcode 26 (17A321). The navigation bar positions under the status bar initially, and after orientation changes to landscape, it positions incorrectly below its expected location. This occurs on both real device (iPad mini A17 Pro) and simulator. My app uses UIKit + Storyboard with a Root Navigation Controller.

When the user taps to focus the field and the text is long, the entire text becomes selected by default. This is the same behavior you can see in iOS Safari’s search field or the Messages app search field. What I want: when the field becomes first responder, the caret should be placed at the end of the text (latest word), without selecting all the text.

It would seem per the HIG that the "pinkJungle" background in the app would be a decent candidate for a launch image, since it will be in the background when the document browser comes up. However when specifying it as the UIImageName, it is not aligned the same as the background image. I'm having trouble figuring out how it should be aligned to match the image.

Tue, 04 Nov 2025 17:58:41 GMT Meyssam https://developer.apple.com/forums/thread/800935 For information I stumbled upon a regression with SwiftUI Slider on iOS 26. Its onEditingChanged closure might be called twice when interaction ends, with a final Boolean incorrect value of true provided to the closure. As a result apps cannot reliably rely on this closure to detect when an interaction with the slider starts or ends. I filed a feedback under FB20283439 (iOS 26.0 regression: Slider onEditingChanged closure is unreliable).
