Unity - using Fabric causes problems with iOS

Question

We're using Fabric with Crashlytics in our Unity Game and after building the iOS project with Unity and starting in Xcode we get about 26 errors:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any idea how we can fix that issue? I checked the files in Unity and it seems everything is imported fine.

Could be any number of things. I'd start with this. http://stackoverflow.com/questions/6429494/undefined-symbols-for-architecture-armv7/10170293 — Terrance, Apr 01 '16 at 21:02
Checked the 'Link Binary With Libraries' as well as the 'Build Phases' and some other solutions suggested there, but didn't help at all. — dabo248, Apr 01 '16 at 21:10

Fixed it somehow through reimporting the whole Fabric SDK in Unity - so deleting all files regarding Fabric and Crashlytics in the project and then importing Fabric again.
