Getting THREAD 1: EXC_BREAKPOINT (code = EXC_ARM_BREAKPOINT...) error when running swift app on iOS device

Question

I'm trying to run an app I've been working on in Swift on my iOS device.

I've run the app on my device in the past and have no problems, I'm getting this problem after running it on the device through Xcode 6 beta 5 for the first time. The app works when it's run in the simulator. I'm thinking this could be an Xcode 6 beta 5 bug but I'm not sure. My device isn't jailbroken, and I've tried restarting the device and reinstalling the app -- nothing has worked. Here is the full error:

Any ideas?

Update: I am now getting another error: ld: library not found for -lswift_stdlib_core for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have no idea why I'm getting these, any ideas?

Answer 1

I had the same trouble. Performing Product->Clean resolved it for me.
