You should use like this then it will work.

NOTE: You can face performance issue by this because it's using recursion in Thread, so for better performance you should use with CATextLayer & CAScrollLayer.

import UIKit
import SnapKit

class ViewController: UIViewController {
    
    let label = UILabel()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        label.lineBreakMode = .byWordWrapping
        label.numberOfLines = 0
       
        label.text = "We couldn't turn around 'Til we were upside down I'll be the bad guy now But no, I ain't too proud I couldn't be there Even when I try You don't believe it We do this every time"
       
        view.addSubview(label)
        label.snp.makeConstraints { (make) in
           make.height.equalTo(20)
            make.top.leading.trailing.equalTo(self.view.safeAreaLayoutGuide).inset(50)
        }
      
        autoScroll()
    }
    
    @objc func autoScroll() {
        UIView.animate(withDuration: 12.0, delay: 1, options: ([.curveLinear, .repeat]), animations: {() -> Void in
            self.label.center = CGPoint(x: 0 - self.label.bounds.size.width / 2,y: self.label.center.y)
        }, completion:  { _ in
            self.autoScroll()
        })
    }
}
