Why using this Swift code in Xcode doesn't work? - swift

Question

Have a problem in Swift. I would like to write a program for the school. For odd tails, A week should be displayed and for even days B week. The date can already read it. But if I always program an ee if condition I always get the error message String. I do not know how to transform it. Can anybody help me further?
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var Datum: UILabel!
#IBOutlet weak var Monat: UILabel!
#IBOutlet weak var Woche: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
let jetzt = Date()
let formatter = DateFormatter()
formatter.dateFormat = "d"
Datum.text = formatter.string(from: jetzt)
let jetzt2 = Date()
let formatter2 = DateFormatter()
formatter2.dateFormat = "M"
Monat.text = formatter2.string(from: jetzt2)
// Do any additional setup after loading the view, typically from a nib.
}
#IBAction func Check(_ sender: Any) {
if Datum.text = "3"
Woche.text = "A-Woche"
}
}

Try this
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var Datum: UILabel!
#IBOutlet weak var Monat: UILabel!
#IBOutlet weak var Woche: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
let jetzt = Date()
let formatter = DateFormatter()
formatter.dateFormat = "d"
Datum.text = formatter.string(from: jetzt)
let jetzt2 = Date()
let formatter2 = DateFormatter()
formatter2.dateFormat = "M"
Monat.text = formatter2.string(from: jetzt2)
}
#IBAction func Check(_ sender: Any) {
if Datum.text == "3"{
Woche.text = "A-Woche"
} else {
Woche.text = "B-Woche"
}
}
}
