You can make this work with a double downcast, first to
In later versions of Swift (at least 1.2), the compiler will complain about
NSArray, then to [String]:var strings = myObjcObject.getStrings() as NSArray as [String]import Foundation
var objCMutableArray = NSMutableArray(array: ["a", "b", "c"])
var swiftArray = objCMutableArray as NSArray as [String]In later versions of Swift (at least 1.2), the compiler will complain about
as [String]. Instead you should use an if let with a conditional downcast as?:import Foundation
var objCMutableArray = NSMutableArray(array: ["a", "b", "c"])
if let swiftArray = objCMutableArray as NSArray as? [String] {
// Use swiftArray here
}NSMutableArray can be cast to [String], then you can use as! instead (but you probably shouldn't use this in most cases):import Foundation
var objCMutableArray = NSMutableArray(array: ["a", "b", "c"])
var swiftArray = objCMutableArray as NSArray as! [String]
