Switching on type of object in Swift

gistfile1.swift

// Playground - noun: a place where people can play

class Abc
{
}

class Def
{
}

// declaring as AnyObject here is important - swich statement gets mad otherwise
let something : AnyObject = Abc()

switch something {
case let something as Abc:
    println("It's an Abc.")
    break;
case let something as Def:
    println("It's a Def.")
    break;
default:
    println("It's something else.")
}


// maybe not as useful but if you only want to know the type and don't need to cast it for whatever reason you can also just provide `let _`:

switch something {
case let _ as Abc:
    println("It's an Abc.")
    break;
case let _ as Def:
    println("It's a Def.")
    break;
default:
    println("It's something else.")
}
