dyld: Library not loaded: @rpath/libswift_stdlib_core.dylib
dyld, swift
Solution
For me none of the previous solutions worked. We discovered that there is a flag `ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES` (in earlier versions: "Embedded Content Contains Swift Code") in the Build Settings that needs to be set to YES. It was NO by default!
Problem
I get this error after adding a Swift class to an old Xcode project. `dyld: Library not loaded: @rpath/libswift_stdlib_core.dylib` How can I make the project run again?
