Just embed in a class:

class Test {
    @objc final func findMatch() {  // not private if you want to access it
         let req = GKMatchRequest()
         req.minPlayers  = 2
         req.maxPlayers = 2
         if let vc = GKMatchmakerViewController(matchRequest: req) {
             vc.matchmakerDelegate = self
             present(vc, animated: true, completion: nil)
         } else {
             UIAlertController.showError(title: "Go To GameCenter", msg: "Matchmaking failed", vc: self)
         }
     }
}

and use as:

let test = Test()
test.findMatch()

Note: where did you define showError ?
