Please see Opting-out of window resizing in iPadOS 26 and UIRequiresFullScreen in iPadOS 26 for existing discussions on this topic.

Did you find a solution to this? I'm trying to do the same thing. I can't find any delegate methods that would tell you the current height of the sheet as it is being dragged. Constraints might work to position the view above the sheet but that won't help to decide when to show/hide the view as the sheet gets higher or lower.

Setting frames and bounds is still supported, even in iOS 26. Constraints have a lot of advantages but they are not required.

Yeah but that's more awkward than the solution I gave. Typing a ! is easier than adding the #else.

It's moved again. In Xcode beta 3 it's now here:

Are you referring to UIAlertController? You don't need an anchor. Just create the alert and present it. It will appear in the middle of the screen. Nevermind. I just noticed this is posted in the SwiftUI section. My answer is for UIKit.

#if !os(visionOS) // some code used on all platforms except visionOS #endif But is it really needed? You can let the code compile for visionOS, just don't release your app for visionOS. In App Store Connect, for your iOS app, under Pricing and Availability, you can uncheck support for visionOS (Apple Vision Pro).

See https://developer.apple.com/forums/thread/792269 which leads to yet another thread with more info.

You can't eliminate the traffic light but you can specify its style a bit. In UIKit you can implement the UIWindowSceneDelegate method preferredWindowingControlStyle(for:) and return one of three styles. I don't know the SwiftUI equivalent.

I really miss that feature too. Related: https://developer.apple.com/forums/thread/791342

Saw this on stack overflow earlier today. See https://stackoverflow.com/questions/79696251/incorrect-uitabbar-appearance-in-ios-26 There is an answer with a workaround.

Not just you. I'm seeing this new issue as well with Xcode 26 beta 3.

Never expect any response to any feedback you submit via Feedback Assistant. It will either get fixed or it won’t. I’ve filed well over a dozen beta bug reports in the last 4 weeks. 3 have been fixed with no feedback. I’m hoping the others get fixed in a future beta. And most of my reports are clearcut bugs that include a trivial app and instructions for reproducing the issue. Also keep in mind, based on the feedback numbers, Apple is getting around 20,000 bug reports per day right now! That’s way too many to expect personal feedback. As for this specific question, don’t expect Apple to reverse its decision on window resizing. Your best solution is to accept that “requires full screen” is going away. But you can set the window’s minimum size in the scene delegate so the user can’t make your window too small.

@mehulFunnmedia I've been using glass alternate icons since beta 1. Can you clarify what's changed in Xcode beta 3?
