Describe the bug

When trying tns run ios --device="device_Id_here" --hmr I get the following error:

Building project...
Xcode build...
2020-01-26 21:47:40.730 xcodebuild[16347:64933]  DTDeviceKit: deviceType from {{uuid}} was NULL
2020-01-26 21:47:41.956 xcodebuild[16347:64853] [MT] DTDeviceKit: deviceType from {{uuid}} was NULL

To Reproduce

tns run ios --device="device_Id_here" --hmr
or
tns build ios --for-device

Expected behavior
App successfully build and deployed to my device

Sample project
Sadly I can't provide you with a sample project but happy to provide any logs necessary.

Additional context
Hello everyone, before anything thanks for taking the time to try to help me with my issue. This error starting to happen a few nights ago. I have seen it before but usually unplugging and plugin my phone back fixed it. Now I can't get past it and I am stuck!

Note: When I build the app with XCode it successfully builds but not when using the commands mentioned above.

Please help 🙏🏽
Thanks!

Research direction

Start by reproducing tns run ios --device="device_Id_here" --hmr or tns build ios --for-device with the listed NativeScript and iOS environment, then compare the CLI result with a successful Xcode build. Done means the CLI build completes and the app deploys to the device without the DTDeviceKit deviceType ... was NULL errors.
