NSClassFromString not totally dynamic - Swift2

I hope this helps you . Based on your code I assume you want dynamically choose a class, and then call known methods. For that you will need to define a protocol first. For example: protocol MyProtocol: class {
init()
var lessonID: String { get set }
func test()
}
let className = "MyModule.MyClass" // this is how swift class names look like
if let classType = NSClassFromString(className) as? MyProtocol.Type {
// call methods from your class, but only those specified in the protocol:
let object = classType.init()
object.lessonID = "15"
object.test()
}

In swift2, is it possible to assign a tuple with 2 elements to 2 variables where one is a constant and one can be mutate

it should still fix some issue In the following example, the xcode compiler has a warning on the first line: Variable 'y' was never mutated, consider changing to let constant. , You can do this with Swift pattern matching: while case (var x, let y)? = stack.tryPop() {
// .. x is mutated
x++
// y is not mutated
}
