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

If using Xcode 4.2 or higher, try the following:

1. Click your Project name (in the left column), followed by the Target:

   

2. Click the 'Build Settings' tab (in the right column):

   

3. Click the 'Release' or 'Distribution' row under 'Architectures', and choose 'Other...':

   

4. Double click the highlighted row named '$(ARCHS_STANDARD_32_BIT)' in the popover that appears, and replace it by typing 'armv6'. Then add a new row with the plus button in the bottom left of the popover, and type 'armv7', then click Done:

   

Update: you should add armv7s to target the iPhone 5 as well. (And drop armv6 if building with Xcode 4.5 or higher, which no longer supports armv6.)

That's it. You should now be able to build/archive without generating errors.

If it still doesn't work, see this answer from justinxreese, which suggests adding entries for armv6 and armv7 under "Required Device Capabilities" in your info.plist file.

Be sure to Verify the BASE SDK used in your project. From the docs:

" Note: If you are building to your development device, the Base SDK version number defined on your Xcode project must be greater than or equal to the software version number on your development device; otherwise Xcode cannot initiate a debugging session with the device. In that case, you will need to download and install the latest iOS SDK version that is greater than or equal to your device software version. "
