Use multiple contains functions in if statement (Swift) - ios

Question

Is there a way to use multiple "contains(array, value)" functions in an if statement? I have a query that stores in the results in an array. If the results are nil I perform a set of operations. If, however, the array is not nil I'd like to check to see if certain objects appear in it:
var user: PFUser?
override func viewDidLoad() {
super.viewDidLoad()
//get the two players
if let user = user{
var userQuery = PFQuery(className: "Game")
userQuery.whereKey("user1", equalTo: user)
userQuery.whereKey("isActive", equalTo: true)
var userQuery2 = PFQuery(className: "Game")
userQuery2.whereKey("user2", equalTo: user)
userQuery2.whereKey("isActive", equalTo: true)
var currentUserQuery = PFQuery(className: "Game")
currentUserQuery.whereKey("user1", equalTo: PFUser.currentUser())
currentUserQuery.whereKey("isActive", equalTo: true)
var currentUserQuery2 = PFQuery(className: "Game")
currentUserQuery2.whereKey("user2", equalTo: PFUser.currentUser())
currentUserQuery2.whereKey("isActive", equalTo: true)
var query = PFQuery.orQueryWithSubqueries([userQuery, userQuery2, currentUserQuery, currentUserQuery2])
query.findObjectsInBackgroundWithBlock{
(results: [AnyObject]!, error: NSError!) -> Void in
if error == nil{
//if there are no active games, start new game
if results == nil{
//start game code
} else if contains(results, user) as [AnyObject]! && contains(results, PFUser.currentUser()) as [AnyObject]! {
println(results)
}
}
}
}
}
Using the && operator is returning an error on the line: Cannot invoke '&&' with an argument of type '([AnyObject]!,[AnyObject]!)'. Any ideas on how I can test to see if the user and PFUser.current_user() objects are found in the array?
Thanks!

Problem is that you are trying to cast result of contains func call which is Bool in to array of AnyObjects's.
What you need to do instead is just to compare results of contains(results, user) and contains(results, PFUser.currentUser()) functions calls. But it wont compile.
In order to make your compiler happy you need to cast results array to array of [PFUser]
See code:
if let users = results as? [PFUser] {
if contains(users, user) && contains(users, PFUser.currentUser()) {
println(users)
}
}
