Thanks for the issue. Could you sent me project with the problem? Which swift version do you use?

[ldiqual]

@wojteklu Unfortunately it is a closed-source project so I can't share it here.

Swift version:

Apple Swift version 2.2 (swiftlang-703.0.18.8 clang-703.0.31)
Target: x86_64-apple-macosx10.9

Will try to find a similar project that fails.

@ldiqual I fixed the problem by adding fallback for nil value. However it would be cool to know file structure with mentioned error. Please check the newest version. Thanks!
