Vertically Display Text

I am trying to display text in a UILabel vertically after the device changes to landscape from portrait.

I've managed to (forcefully) stack them vertically by changing its frame size and setting numberOfLines = 0.
This sort of produces the result I want, except I get white spaces between each character after rotation, elongating the word greatly.
Please check the link below to get a better idea of what I am experiencing.

Ideally, there would be no unnecessary white spaces after ratation, and it would be nice and compact like it is in Portrait.
Does anyone know how I can achive this? Below is my code:

import UIKit

class ViewController: UIViewController {
    
    var _W = CGFloat()
    var _H = CGFloat()
    
    var wordLabel: UILabel!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        _W = UIApplication.shared.statusBarOrientation.isPortrait ? view.frame.width : view.frame.height
        _H = UIApplication.shared.statusBarOrientation.isPortrait ? view.frame.height : view.frame.width
        wordLabel = UILabel()
        wordLabel.text = "Text"
        view.addSubview(wordLabel)
        formatLabel(label: wordLabel, fontSize: 64, color: UIColor.magenta, tag: 1)
    }

    func formatLabel(label: UILabel, fontSize: CGFloat, color: UIColor, tag: Int) {
        label.font = UIFont.boldSystemFont(ofSize: fontSize)
        label.textColor = color
        label.tag = tag
        label.textAlignment = .center
        label.adjustsFontSizeToFitWidth = true
        label.numberOfLines = 0
        positionView(label, isPortrait: UIApplication.shared.statusBarOrientation.isPortrait)
    }
   
    override func willTransition(to newCollection: UITraitCollection, with coordinator: UIViewControllerTransitionCoordinator) {
        positionView(wordLabel, isPortrait: !UIApplication.shared.statusBarOrientation.isPortrait)
   }
    
    func positionView(_ view: UIView, isPortrait: Bool) {
        if (view.tag == 1) {
            if (isPortrait) {
                wordLabel.frame = CGRect(x: 0, y: 0, width: _W, height: 80)
                wordLabel.center = CGPoint(x: _W/2, y: (_H - _W)/4)
            } else {
                wordLabel.frame = CGRect(x: 0, y: 0, width: 50, height: _W)
                wordLabel.center = CGPoint(x: (_H - _W)/4, y: _W/2)
            }
        }
    }
    
}
