I was getting the error after updating my project to consolidate watchOS app extension and app targets. Adding a WKApplication key to the watch app's Info.plist (type: boolean, value: 1) fixed this for me.

Still having this issue with Xcode 12 GM and iPhone XR running iOS 13.7 and also iPhone 7 running iOS 14 GM. On a separate Mac using these devices with Xcode works, so I suspect the issue is on the Mac. What can I do to "reset" the dev environment on this Mac?

Recovery Suggestion: If you are certain that Xcode supports development on this device, try disconnecting and reconnecting the device.

NSLocalizedFailure = "This operation can fail if the version of the OS on the device is newer than the version of Xcode that is running.";

I am now getting this crash since installing Xcode 12 beta 6. I was not getting it in any of the previous betas. It happens on every launch, same assertion failure and callstack as above.
As a workaround, I ended up just moving the xip to a large external HDD, extracting it there, then copying the Xcode12-beta.app back over to my main volume. I had 14GB of 'purgeable' space showing in Disk Utility fwiw.

I am experiencing this problem with my watchOS app. On Xcode 8 / Switft 3 my watchOS app was under 50MB but after switching to Xcode 9 and updating my app to Swift 3.2 using the migrator (no other code changes or additions) my watch app is now 58MB and I am not able to submit updates to the App Store. The only files that inceased in size between the two versions are the swift runtime libraries.
