*** error: Couldn't codesign /Users/steve/Library/Developer/Xcode/DerivedData/Passenger_Party-birhcpgkoghbjldrxppcdrafwukb/Build/Products/Debug-iphoneos/Passenger Party.app/Frameworks/libswiftCore.dylib: codesign failed with exit code 1

I get the above error for all of my Swift projects, even if I create a brand new one. I have tried revoking and renewing my certificates and profiles as well as re-installing xcode 6.4. I have confirmed the codesign_allocator file is in /usr/bin and that it's part of my $path. The weirdest thing is that my other project written in objective-c has no issues building to my phone successfully.
Has anybody had this problem? Is there any more information I can add to make this more clear? I've spent two evenings trying to fix this and have had no success.
