Recently upgraded my iOS device and was surprised to find that Xcode 12 Beta 6 now gives the following error:


The current device configuration is unsupported. This iPhone 8 (Model A1863, A1905, A1906, A1907) is running iOS 13.7 (17H35), which is not supported by Xcode 12.0.
Domain: com.apple.dtdevicekit
Code: 601
Recovery Suggestion: To run on this device, please update to a version of Xcode that supports iOS 13.7. You can download Xcode from the Mac App Store or the Apple Developer website.


Anyone else run into this issue? Is there any way around this using Xcode 12?

I have the same problem with Xcode 12 beta 6 and an iPhone X running iOS 13.7. (It was working previously when I had 13.5 installed.)

Glad to see I'm not the only one running into this issue with Xcode 12 beta 6, and an iPhone 11 Pro running 13.7.

I also can't compile in Xcode 11 because the AppDelegate uses @main and I get the error: Unknown attribute 'main'

What a mess!

I just started receiving this same error, with an ipad 5th gen. I'm running Xcode 12 Beta 2. I've tried rebooting computer, restarting XCode, cleaning project, deleting derived data, and re-pairing the device. Nothing has worked so far.

Same problem here with Iphone 7, IOS 13.7 and XCode 12 beta 6. Simulator works but when trying to build on phone I get the same error message.

Same problem for me as well. My iPad Pro 12.9 Gen 4 was recently upgraded to iPadOS 13.7 and now my builds have the message: "iPad 12.9 Gen 4 (2) is not available." This error happens in both Xcode Version 12.0 Beta 6 (12A8189n). I ran a build 2 days ago just fine with very limited changes. In addition, I ran an unchanged build and it had the same error. Appreciate anyones help! Thanks!

Hi everyone,

I am now able to successfully preview a build on my iPad without error. The only think that seems to have changed was an update to Safari (ver 14.0 15610.1.28.1.9, 15610). I don't know if it had anything to do with it but after doing the update, I was working.

@main in app delegate loaded without any issue!

Hi all, had the same problem and couldn't work it out.
However, downloading the new version of Xcode 12.3 (12C33) fixed the error for me.


Hope this helps.
