Question

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

Answer 1

After having tried out everything, I finally found out, that the build seems not always include every detail again and again. Maybe for speeding up the process... In order to ensure WHOLE packaging before running on a device, make a Clean first: Shift-Cmd-K. Then build with: Cmd-B. After that run it on your device. Easy. Kind regards to all you nice guys in that place!
