Get the name (string) of a generic type in Swift

Question

I have a generic class of type T and I would like to get the name of the type that passed into the class when instantiated. Here is an example.

class MyClas         


        

Answer 1

You can return any types' name by using string interpolation:

class MyClass {
    func genericName() -> String {
        return "\(T.self)"
    }
}

You can try it in a playground and it works as expected:

var someClass = MyClass()
someClass.genericName() // Returns "Swift.String"
