Not getting correct height of UILabel in Objective-c

Question

I have string with multiple new line characters like below.

"sdfsdghhfdgdfgfdgdfghjgf
sdfsdfsdfsdfdsfdsfdsgdfgfdhghgfhfgjhf

sdfdsfdsfdsfdsfdsfdsfhhg
sdfsdfdfsd
sdfdsfdsfdsfdsfdfdsfsdf"

Now I am calculating height of label to accommodate above string. Below is my code for it.

label.numberOfLines = 0;
label.lineBreakMode = NSLineBreakByWordWrapping;
label.font = font;
label.text = labelText;

float width = label.frame.size.width;
CGSize jobDescHeightSize = [label sizeThatFits:CGSizeMake(width, CGFLOAT_MAX)];

It gives me correct height in larger device i.e. iPhone XR, iPhone 11 but it doesn't give me correct size of UILabel in iPhone 6s, iPhone 8.

The extension which solved my issue once

extension UILabel{

public var requiredHeight: CGFloat {
    let label = UILabel(frame: CGRect(x: 0, y: 0, width: frame.width, height: CGFloat.greatestFiniteMagnitude))
    label.numberOfLines = 0
    label.lineBreakMode = NSLineBreakMode.byWordWrapping
    label.font = font
    label.text = text
    label.attributedText = attributedText
    label.sizeToFit()
    return label.frame.height
  }
}
