问题
I'm getting a JSON crash when I try to launch an app that uses the Simperium framework:
[__NSCFString objectFromJSONString]: unrecognized selector sent to instance 0x6c561a0
It happens immediately. Am I missing an external dependency? It looks like a JSONKit method.

Simperium uses JSONKit internally. You'll need to add -ObjC to your Other Linker Flags (found under Build Settings in your target).
