Everything worked perfectly with Xcode 13.3.1 and iOS 15.5 beta on the iPhone X, I could run the app directly on the iPhone X (90GB free).

After installing Xcode 13.4, everything continued to work perfectly, running the app directly on the iPhone X. I installed iOS 15.6 beta 1, and it shows me the following error.

Failed to prepare device for development. This operation can fail if the version of the OS on the device is incompatible with the installed version of Xcode. You may also need to restart your mac and device in order to correctly detect compatibility.

I completely (totally) uninstalled Xcode 13.4, and reinstalled (Xcode didn't even keep the project list open lately). I have restarted the iPhone X multiple times.

How can I overcome this error without having to downgrade to iOS 15.5?

I have checked the compatibility list within the Xcode.app package, yet it shows iPhone X. To get into 'Device Support' :: Open Finder -> Applications -> Scroll to Xcode -> Right Click -> Show Package Contents -> Contents -> Developer -> Platforms -> iPhoneOS.platform -> DeviceSupport This is the list of devices folder support for your Xcode

The app project is on iOS 15.4.

Thanks in advance.

Why is Apple releasing new iOS versions without supporting them in the current Xcode version?

This doesn't make any sense. A large company may be able to have multiple computers in use for programming. But the little programmer only has 1 Mac, and managing space to have 2 Xcode installed is crazy, especially on a 256GB Mac.

Having the same issue. iOS 16.5.1 - there is no such folder in the XCode 'Device Support' folder. Is it for me only or Apple actually releases its software without full compatibility?
