Are you decoding it from a 64 bit app? Because CGRect on 64 bits is made of doubles, while on 32 bits (where it was probably encoded) it was made of floats....
Also, the exact format for @encode() varies greatly between compiler version (especially with regards for things like structure names vs ?, etc...). This, in and of itself, shouldn't make it incompatible, but a structure with two structures each with two floats doesn't match with the double-based CGRect.
