I am trying to run a Swift app on my iPhone 4s. It works fine on the simulator, and my friend can successfully run it on his iPhone 4s. I have iOS 8 and the official release of Xcode 6.
I have tried
- Restarting Xcode, iPhone, computer
- Cleaning & rebuilding
- Revoking and creating new certificate/provision profile
- Runpath Search Paths is $(inherited) @executable_path/Frameworks
- Embedded Content Contains Swift Code is 'Yes'
- Code Signing Identity is developer
Below is the error in entirety
