Pass Tuples as AnyObject in swift

Tuples are no Objects, so this won't work. However if you change AnyObject to Any, you can pass objects as well as tuples:

func getWithPath(path:String, userState: Any)

From swift docs

You’ll have access to anything within a class or protocol that’s marked with the @objc attribute as long as it’s compatible with Objective-C. This excludes Swift-only features such as those listed here: 7 Generics

TuplesEnumerations defined in SwiftStructures defined in SwiftTop-level functions defined in SwiftGlobal variables defined in SwiftTypealiases defined in SwiftSwift-style variadicsNested typesCurried functions

For example, a method that takes a generic type as an argument or returns a tuple will not be usable from Objective-C.

So you can not use tuple for AnyObject as there is no matched objective c object for tuple.Instead use Dictionary to pass as parameter

Use dictionary instead

var abc:[String:AnyObject] = ["abc":123,"pqr":"not"] you can use AnyObject for thar

Use this for your dictionary

let userState:[String:AnyObject] = ["name": "temp", "callingDate": NSDate(), "randomValue": 2345]
