Getting values from labels and adding together in another label - ios

Question

I'm trying to get the int values from my labels and pass them to another label and add them together. In the code below, kicklabel, handballlabel, marklabel, etc., all need to add up and equal into fantasylabel. Based on how this code is set up, I'm not sure how to perform that.
I want to be able to add more lines of labels also, so that any amount of the array of labels add to a fantasy label.
Here's the code:
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var kickLabel1: UILabel!
#IBOutlet weak var handballLabel1: UILabel!
#IBOutlet weak var markLabel1: UILabel!
#IBOutlet weak var tackleLabel1: UILabel!
#IBOutlet weak var goalLabel1: UILabel!
#IBOutlet weak var pointLabel1: UILabel!
#IBOutlet weak var freeForLabel1: UILabel!
#IBOutlet weak var freeAgainstLabel1: UILabel!
#IBOutlet weak var fantasyLabel: UILabel!
var counters: [UILabel: Int] = [:]
override func viewDidLoad() {
super.viewDidLoad()
for label: UILabel in [kickLabel1,handballLabel1,markLabel1,tackleLabel1,goalLabel1,pointLabel1, freeForLabel1, freeAgainstLabel1, fantasyLabel] {
counters[label] = 0
for direction: UISwipeGestureRecognizerDirection in [.up, .down, .left, .right] {
let swipeGesture = UISwipeGestureRecognizer(target: self, action: #selector(didSwipe(_:)))
swipeGesture.direction = direction
label.addGestureRecognizer(swipeGesture)
label.isUserInteractionEnabled = true
label.isMultipleTouchEnabled = true
}
}
}
#objc func didSwipe(_ gestureRecognizer: UISwipeGestureRecognizer) {
guard let label = gestureRecognizer.view as? UILabel else { return }
debugPrint("\(gestureRecognizer.direction)")
switch gestureRecognizer.direction {
case .up:
counters[label] = counters[label]! + 10
print(counters)
case .down:
counters[label] = 0
print(counters)
case .left:
counters[label] = counters[label]! - 1
print(counters)
case .right:
counters[label] = counters[label]! + 1
print(counters)
default:
counters[label] = 0
}
label.text = "\(counters[label]!)"
}
}

Answer 1

At the end of your didSwipe you need to sum all of the Int values stored in your counters dictionary. Then update your fantasy label with that sum.
let sum = counters.reduce(0) { $0 + $1.value }
fantasyLabel.text = "\(sum)"
And you probably don't want a gesture on the fantasy label since that value is read-only based on the sum of the other data.
I would also get rid of the individual label outlets except for the fantasy label. Use an IBOutletCollect to store an array of UILabel.
