I've made a rather horrid work around for now so I can run UITests against different installed data using a shell script, xcodebuild and simctl. Basically I create a simulator, I run xcodebuild test with a dummy test run to install the app on the simulator, use simctl get_app_container to get the apps data container, then using cp to copy individual directories from my xcappdata into their equivalents in the data container. Finally I run xcodebuild test with my actual test plan. This is very slow, and the shell script seems to frequently hang for a while after completing a test run.

Also bumping, it's nice to have this functionality in the simulator, I have to constantly run a projector next to me otherwise. Also, please add something to simctl or devicectl to programmatically connect and disconnect screens.

OK, reading the article again it was easy to fix, I just added the following to my root view controller and it started working again: @interface MainViewController () @property (nonatomic, nullable) UISceneAccessoryRegistration *externalDisplayRegistration API_AVAILABLE(ios(27.0)); @end @implementation MainViewController - (void) viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. if (@available(iOS 27.0, *)) { // Support for new external display registration UISceneConfiguration *sceneConfiguration = [UISceneConfiguration new]; sceneConfiguration.delegateClass = [MyExternalDisplayWindowSceneDelegate class]; UISceneAccessory *sceneAccessory = [UISceneAccessory externalNonInteractiveSceneAccessoryWithConfiguration:sceneConfiguration]; self.externalDisplayRegistration = [self registerSceneAccessory:sceneAccessory]; } } The original article provides swift. Be careful to specify your own window scene delegate. It seems ok to leave the original code where it is so previous versions work too.

I see now, the article https://developer.apple.com/documentation/uikit/presenting-content-on-a-connected-display?language=objc has a new workflow for iOS 27, it would be nice to make the previous method as deprecated it's no longer called!

I can go into device hub, and get it to show me the location of a simulator, and it opens a finder window in 'Devices' which has symlinks to the devices. But I have no idea where that directory is. I can find the simulators in ~/Library/Developer/CoreSimulator/Devices like before, but the directory structures don't look like the ones revealed by device hub. So I search my mac for the same directory names as the ones in 'Devices' but they're nowhere to be found. so even if I want to write a script, the directory locations are a total mystery.

A full restart fixed it

For me, since the last 2 days, I'm guessing since the release of 4.7, the claude agent no longer works at all for me in xcode, every request repsonds with "Your request couldn't be completed." I'm paying for this....
