CodePudding user response：

Please open up a fresh playground and paste the following code in:

import UIKit

let label = UILabel()

label.text = " 0 \n000"      // simple demo text
label.numberOfLines = 0      // unlimited number of lines
label.font = .monospacedSystemFont(ofSize: 14, weight: .regular) // monospaced font so that columns are aligned
label.sizeToFit()            // tell the label to evaluate its content and adjust its size to fit

It should display a basic example of what you want and give you all the information you need to update your code accordingly.
