“The run destination iOS Device is not valid for running the scheme”

Question

I\'ve been running my app on an iPhone 5 /iOS 6, but when I try to run it on an iPhone 4S / iOS6 I get \"The run destination iOS Device is not valid for running the scheme N

Answer 1

I had this problem in XCode 9.0.1.

It seems that XCode does not refresh the list of connected devices.

You may notice that after disconnecting your device, you can still choose it as a target. So XCode may actually be trying to connect to a bogus device.

To fix this:

1. Edit the scheme.
2. Re-select the scheme's executable.
   • this seems to force XCode to update the list of connected devices.

If that did not work, try reconnecting your device (cable) before you do this.

Or perhaps, some other combination of disconnecting device, connecting device, and re-selecting the scheme's executable.

As a desperate measure, you may also try to change the cable that connects your mobile device to your pc.

But ideally... Xcode should be fixed.
