Swift: check if generic type conforms to protocol

Question

I have a protocol that I defined like so:

protocol MyProtocol {
   ...
}

I also have a generic struct:

struct MyStruct <         


        

Answer 1

you can also leverage swift's switch case pattern matching, if you want to handle multiple cases of type T:

func myFunc(s: MyStruct) -> T? {
    switch s {
    case let sType as MyProtocol:
        // do MyProtocol specific stuff here, using sType
    default:
        //this does not conform to MyProtocol
    ...
    }
}
