Is this just a test to narrow down the error? Because this code doesn’t actually do anything — it just declares a block literal, casts it to type ‘id’, and ignores the result.
I’m not sure how you explicitly specify the return type of a block, since usually it’s inferred for you by the compiler. You could try assigning the block to a variable of the type you want:
id myblock = ^(id inParam1) { … };
The compiler will then infer that the return type of the block is ‘id’.
