Is there a shortcut for wrapping a variable with a cast that is inferred by the IDE?
0
Just wondering if there is a convenience shortcut/chord for this. The IDE obviously knows the return type.
This is specific to Objective-C in the IDE, it seems that the IDE has this functionality when I use swift.

Can you provide an example of what you are trying to do?

Say I have a method that returnsUINavigationController *and I've performed some stupid hierarchy walk and have done something like[vc isKindOfClass:UINavigationController.class]and going to typereturn vc;is going to give me an obvious warning. The IDE knows it's supposed to be cast toUINavigationController *. In Swift the IDE performs this functionality -- hence the question here for Objective-C.

Ah, ok. Without seeing code, I can't provide a concrete answer.instancetypemight be your friend, but there might still be an explicit cast needed somewhere. Details: nshipster.com/instancetype

Thanks for the comment, but this is not an issue of type inference (the IDE is already aware of the type that I want to cast), it's not a code question.Incompatible pointer types returning 'UIViewController *' from a function with result type 'UINavigationController *'-- the IDE is aware I want to usevcas aUINavigationController *, and I've already done the reflection test.

The compiler isn't aware, though. Reflection tests are purely runtime; they don't influence the compiler's type checking at all. Can you show your method, please?
