问题 I am currently getting a weird warning from Xcode 11.5 (I'm using the release version): The Mac Catalyst deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 13.5, but the range of supported deployment target versions is 13.1 to 13.4.99. I did a web search and haven't seen this message mentioned by anybody. Now, I could set my deployment back to iOS 13.0 (I'm not using any special features in iOS 13.5 in my project), but was wondering why this particular warning is being issued? Certainly
