Strings in Switch Statements: 'String' does not conform to protocol 'IntervalType'

Question

I am having problems using strings in switch statements in Swift.

I have a dictionary called opts which is declared as

Answer 1

Instead of the unsafe force unwrap.. I find it easier to test for the optional case:

switch opts["type"] {
  case "abc"?:
    println("Type is abc")
  case "def"?:
    println("Type is def")
  default:
    println("Type is something else")
}

(See added ? to the case)
