Generate a UUID string with ARC enabled

Question

I need to generate a UUID string in some code with ARC enabled.

After doing some research, this is what I came up with:

CFUUIDRef uuid = CFUUIDCreate         


        

Answer 1

From clang docs:

(__bridge_transfer T) op casts the operand, which must have non-retainable pointer type, to the destination type, which must be a retainable object pointer type. ARC will release the value at the end of the enclosing full-expression, subject to the usual optimizations on local values.

So you are doing it right.
