When using UITraitBridgedEnvironmentKey to pass a trait value to the swift environment, it causes a crash when trying to access the value from the environment. The issue seems to be related to how swift uses the UITraitBridgedEnvironmentKey protocol since the crash occurs in swift::_getWitnessTable () from lazy protocol witness table accessor…. It can occur when calling any function that is generic using the UITraitBridgedEnvironmentKey type. I originally encountered the issue when trying to use a UITraitBridgedEnvironmentKey in SwiftUI, but have been able to reproduce the issue with any function with a similar signature. https://developer.apple.com/documentation/swiftui/environmentvalues/subscript(_:)-9zku Steps to Reproduce Requirements for the issue to occur Project with a minimum iOS version of iOS 16 Build the project with Xcode 26 Run on iOS 18 Add the following code to a project and call foo(key: MyCustomTraitKey.self) from anywhere. @available(iOS 17.0, *) func foo(key: K.Type) where K: UITra

I used to develop iPhone apps about a decade ago and am now back at it with an iPhone and companion Apple Watch app. Why does it suck so bad? I a must be doing something wrong, but what I am doing is out of the box. The majority of the time when I go to build on the watch I get: Previous preparation error: A connection to this device could not be established.; Timed out while attempting to establish tunnel using negotiated network parameters. Which I then first try to force quit the app on the watch and if that does not work, reboot the watch (which is pretty ridiculous). I tried Gemini and it gave me the following explanation: This is arguably the single most frustrating error in the entire watchOS development ecosystem. As an expert, I can tell you that you are not doing anything wrong; you are fighting a fragile architecture. Here is the technical breakdown of why this happens and a workflow to mitigate it without constant reboots. The Technical Why This error message reveals that the issue lies in the Cor

Hello! I'm trying to upload images to Swift Playground on XCode, and it's not working. When I created my playground, there is no Resources folder or an assets file. If I simply drag an image file to the sidebar, the image is not showing up when used in the app. This may be a simple fix, but as a beginner, I am struggling to find the solution. Any help would be much appreciated! Thank you!
