dyld: Library not loaded: @rpath/libswiftCore.dylib

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

I was having this issue with running my Swift tests (but not my app). It turns out that the test needed to have more than @executable_path/Frameworks in it's Runpath Search Paths build setting for the test target. Setting the Runpath Search Paths to the following worked a charm for me:

$(inherited)
@executable_path/Frameworks
@loader_path/Frameworks
