Dynamic type checks with type object?

[robnik]

I know how to get an instance of a metatype...

let t = type(of: obj)  // or...
let t = SomeType.self  

But is there a way to check another instance obj2 to see if it is assignable to that type t? I can say t == type(of: obj2) but that doesn't account for subclasses and protocols.

If you want to use a constant or variable as a type, you won't be able to use type casting. But you can use

conforms(to:) or isKind(of:)

However, keep in mind that often when this question arises, there is something wrong in the approach used.
