Error when building Swift with the Xcode option

Development Compiler
1

I'm trying to build Swift and choose the --xcode option, but I have errors like this that are constantly repeated:

iPhoneSupport: 📱<DVTiOSDevice (0x7fb7ba66ac40), iPhone de Trevör, iPhone, 13.0 (17A5565b), [a device id]> unable to mount DeveloperDiskImage (Error Domain=com.apple.dtdevicekit Code=-402653052 "Xcode encountered an error" UserInfo={NSLocalizedFailureReason=This device is no longer connected., com.apple.dtdevicekit.stacktrace=(

Is there something I can do about this?

Maybe it's because you're running an older Xcode 11 beta and a newer iOS 13 beta?

I faced the same problem, but I have the latest Xcode (11 beta 7) and an old iOS 13 beta.

Yeah, I think you need to use the latest Xcode beta and iOS 13 beta. Although I don't think Xcode 11b7 has the developer image for iOS 13.1...

Anyway, my project was build successfully, even with these errors

Thanks to everyone for your replies, I'll try it again with the correct versions!

I don't actually get this as an error though (more like a warning/note), I am able to build the compiler just fine.
