IOS development path-xcode cannot run using the selected device. Solution

1. Restart (of course, this method usually does not work)

2. Check whether the certificate is correct

3. Set the value in project --> info --> deployment target --> IOS deployment target to <= real machine system version

Targets --> summary --> IOS application target --> set the value in deployment target to <= real-machine system version

Check whether the two are correct.

Project --> build settings --> deployment --> IOS deployment target

Targets --> build settings --> deployment --> IOS deployment target
