I hope this helps . I know you accepted an answer already, but if you want to have both preset and customizable difficulty setting i'd suggest doing it like that:
code :
enum Difficulty {
   case easy
   case medium
   case hard
   case custom(min: Int, max: Int)

   var min : Int {
       switch self {
       case .easy:
           return 50
       case .medium:
           return 200
       case .hard:
           return 500
       case .custom(let min,_):
           return min
       }
   }

   var max : Int {
       switch self {
       case .easy:
           return 200
       case .medium:
           return 500
       case .hard:
           return 1000
       case .custom(_,let max):
           return max
       }
   }
}
let difficulty : Difficulty = .easy
let customDifficulty : Difficulty = .custom(min: 70, max: 240)

let easyMin = difficulty.min
let easyMax = difficulty.max

let customMin = customDifficulty.min
let customMax = customDifficulty.max

Why is asynchronous network testing difficult in Objective-C/Swift?

Why is asynchronous network testing difficult in Objective-C/Swift?

wish help you to fix your issue Breaking down this statement tells us that each test method finishes when it returns. Because you are testing network code with an async callback, the callback may not happen BEFORE the method ends. Therefore testing async code can be considered potentially difficult ** if you don't pay attention **
To this I will add that I am using the simple dispatch group to wrap code and wait for the code to finish. Here is a great example that I have inspired myself from to test my own code.
background processing a difficult task on viewDidLoad in swift

background processing a difficult task on viewDidLoad in swift

it helps some times I am currently making an app which initiates a very long task on the viewDidLoad method. The nature of it is stopping the view from loading at all for extended periods of time and sometimes causes the app to crash. As such, I need to be able to process this particular task in the background so that the view can load instantly and then, in the background, complete the task and update the view when it is done. Does anybody know how to do this? , Try to use GCD similar to this:
code :
let backgroundQueue = dispatch_get_global_queue(CLong(DISPATCH_QUEUE_PRIORITY_HIGH), 0)
dispatch_async(backgroundQueue) {
    // Do your stuff on global queue.

    dispatch_async(dispatch_get_main_queue(), { () -> Void in
        // After finish update UI on main queue.
    })
}

I hope this helps you . There is no method updateLabels() in your ViewController class. Take a look:
code :
class ViewController: UIViewController {
    func startNewRound() {
        targetValue = 1
    func updateLabels() {
        targetLabel.text = "\(targetValue)" } // <- see?
    }
    override func viewDidLoad() {
        super.viewDidLoad()
        updateLabels()
    }
}
class ViewController: UIViewController {
    func startNewRound() {
        targetValue = 1
        func updateLabels() {
            targetLabel.text = "\(targetValue)"
        }
    }
    override func viewDidLoad() {
        super.viewDidLoad()
        updateLabels()
    }
}

With these it helps My Firebase database looks like this , Here is how you can update one value at a time for example,
code :
let ref : FIRDatabaseReference!
    ref = FIRDatabase.database().reference()
    ref.child("yourNode").child("subNode").updateChildValues(["yourKey": yourValue])
ref.child("yourNode").child(postKey).updateChildValues(["key": yourValue])
