I recently upgraded windows visual studio to 17.5.4
Windows Xamarin Forms to 5.0.0.2545
When I try to debug the Xamarin iOS application I get the following: error MT1007: Failed to launch the application '/Users/Library/Caches/Xamarin/mtbs/builds/MyApp.iOS/8a8b8e8316262bab894c6e0f820cac3c5cfb742bfa540e885b14062f62d65d01/bin/iPhone/Debug/device-builds/iphone12.1-16.4.1/MyApp.iOS.app' on the device 'iPhone (2)': Failed to launch the application 'com.MyApp.' on the device 'iPhone (2)': Invalid Service Error (error: 0xe8000022)
My build machine on the MAC says that XCode and Visual Studio are up to date.
The app still deploys but to the phone but it will not launch the app nor debug the app

If your XCode version is 14.2 or later, XCode 14.2 later is not supported yet. Please download Xcode 14.2 from the downloads page in the Apple Developer Portal and continue to use it. Please check the update progress with [META] Xcode 14.3 Support for Xamarin, .NET 6/7 and MAUI

I downloaded the new Xcode 15.0 on my iMac. Is Xcode 15.0 already supported in Visual Studio for Mac 17.6.4 (build 472) or Visual Studio for Mac 17.6 Preview (17.6 build 1569)?
Should I use a different Xcode version?

For a few weeks now, that's why I can't move forward with the release of the IPhone application.

Rob Caplan - MSFT 5,537 Reputation points Microsoft Employee2023-12-01T02:41:55.44+00:00 @Sápi Sándor, please open a new thread for your scenario with full details of your version numbers, what you're doing, and the behaviour you are getting.
Bumping an old thread on a different (even if similar) topic is unlikely to get a proper answer.
Note that at the time this thread was created, Xamarin did not support XCode 15, so your initial MT1007 errors were expected. XCode 15 is now supported with Visual Studio 2022 17.8. Your new MT 1045 error will need its own thread and more clear details.
