Xcode 10.3 failing to run on iOS 13 iPhone X - This iPhone X is running iOS 13.0 (17A577), which may not be supported by this version of Xcode

Question

I updated to iOS 13 on my iPhone X and have Xcode 10.3 and am unable to run my project ton my phone. It gives me a notice of:

Could not locate device

Answer 1

Your version of Xcode does not have the supporting files for running iOS 13. The easiest way to do that is to have Xcode 11 installed on your mac (or on someone else's mac) in addition to Xcode 10.3 (it's better to rename one of them)

Go to Applications folder, right click on Xcode 11 icon → Show Package Contents, navigate to folder Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

And copy the folder 13.0

Go back to Applications, right click on Xcode 10.3 icon → Show Package Contents, navigate to folder Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

Now, paste that folder.

Quit Xcode and run again. Happy Coding
