Simple as that:

let someArray = myArray as? [[String:String]]

Optional casting is recommended if you want to make sure you don't get any crashes when converting. You can then use it in if-let constructions like this:

if let dictArray = myArray as? [[String:String]] {
    // do something with the array of dictionaries
}

BTW, your initial definition was not correct, there's no such thing as Dictionary<String:String>, the correct definition is Dictionary<String, String>.

(Dictionary<String:String> was the syntax used in early Swift releases.)

Hmm... I hope the OP is up-to-date with Swift :)

What do you mean by "it didn't work": did you get a crash, or did the if code was not executed? Could you also give some sample of the Objective-C array you are trying to convert?
