Compiler Error with LLVM 5.1 "Deprecated isa"

Question

I am getting compiler errors with libJSONKit and in JSONKit.m. The errors are thrown with this: "Assignment to Objective-C's isa is deprecated in favor of object_setClass()".
There is also a secondary error: "Direct access to Objective-C's isa is deprecated in favor of object_getClass()".

Any advice on workarounds or solutions?

Answer 1

Simply follow the advice in the error message:

Change:

object->isa  = SomeClass;

to:

object_setClass(object, SomeClass);
