Hello! I am creating UIView (subview of main view) and I want to add gradient for background, but I don't use CGRect for create UIView only autolayout therefore my UIView has coordinates 0, 0, width 0 and hight 0.

What should I do? //gradient var gradient: CAGradientLayer = {         let gradient = CAGradientLayer()         gradient.colors = [             UIColor(red: 25/255, green: 25/255, blue: 186/255, alpha: 1).cgColor,             UIColor(red: 177/255, green: 146/255, blue: 125/255, alpha: 1).cgColor         ]         gradient.startPoint = CGPoint(x: 0, y: 0.5)         gradient.endPoint = CGPoint(x: 1, y: 0.5)         return gradient }() //UIView var win: UIView = {     let view = UIView()     view.translatesAutoresizingMaskIntoConstraints = false     view.layer.addSublayer(gradient)     gradient.frame = view.bounds     return view }() //layout func winConstraint(_ collections: UICollectionView, _ view: UIView, _ btn: UIView) {     btn.leftAnchor.constraint(equalTo: view.leftAnchor, constant: 25).isActive = true     btn.rightAnchor.constraint(equalTo: view.rightAnchor, constant: -25).isActive = true     btn.topAnchor.constraint(equalTo: collections.bottomAnchor, constant: 8).isActive = true     btn.heightAnchor.constraint(equalToConstant: 100).isActive = true } //from ViewController view.addSubview(win)

Hello! I created my own pass with nfc and want to test it on my iphone, how can i do that?

when i use shortcuts -> automatization-> creat automatization -> NFC. My iphone can see my tag. But when I create my own project with coreNFC to detect nfc tag, my iphone cant see my tag, but it see other tag. Tag mifare import UIKit import CoreNFC class ViewController: UIViewController, NFCTagReaderSessionDelegate {     @IBOutlet weak var UIDLabel: UILabel!     var session: NFCTagReaderSession?     override func viewDidLoad() {         super.viewDidLoad()         // Do any additional setup after loading the view.     }     @IBAction func CaptureBtn(_ sender: Any) {         self.session = NFCTagReaderSession(pollingOption: .iso14443, delegate: self)         self.session?.alertMessage = "Hold Your Phone Near the NFC Tag"         self.session?.begin()              }     func tagReaderSessionDidBecomeActive(_ session: NFCTagReaderSession) {         print("Session Begun!")     }     func tagReaderSession(_ session: NFCTagReaderSession, didInvalidateWithError error: Error) {         print("Error with Launching Session")     }       func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) {         for nfcTag in tags {             print(nfcTag)         }     } }

Do I need pay taxes by myself or it charges automatically from my account?
