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

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 NN. The Scheme contains no buildables that can be built for the architectures supported by the run designation device".

I've looked at previous postings on this but they involve issues with the Deployment Target. In my case I've got the Base SDK set to 6.1 and the Deployment Target set to 5.0.

The iPhone 4 has got iOS version 6.0.1.

It was a bug in XCode, I closed and reopened Xcode and it started working.

I've noticed this sort of thing many many times now with Xcode with other problems, its very frustrating that the tool is so dodgy.

I had the same problem. The issue that i found is that , by mistake I had chosen iPad as deployment target due to which XCode showed that iPhone 5 is an invalid device. . Hope it helps. Then I just changed the target to iPhone and it worked.

The run destination iPhone is not valid for Running the scheme.

• Quit Xcode
• Open Xcode
• Clean project
• Run project

It will work

This is some sort of memory issue sometimes.Close some application and try again.

Close Xcode too and reopen. Worked for me.

Cheers.
