The reason for the problem is simple , Is the lack of the corresponding version of the real debugging support files .
It is usually downloaded from the Internet or from the latest Xcode Copy the file in , But if the new version of the release time is very short , It can't be downloaded from the internet yet , Or you don't want to download it 7,8GB Of XCode, What about it ?
Take a chestnut , When writing this article iOS 13.5.1（17F80） It wasn't long before it was released , The debugging support files for this version cannot be found on the Internet .
What I developed is 12 Year's MBA, Storage only 128GB, It's almost full , Unable to download the latest Xcode, Let alone download and unzip .
my Xcode The version is 11.3.1,Mac The system version is Mojave 10.14.6, therefore Xcode The version can no longer be updated .
My real machine is upgraded to 13.5.1 after , use Xcode Debug prompt for current version of Xcode Cannot support debugging 13.5.1 Version of the device , The prompt is similar to the following :
