If you still want to use Auto Layout Constraint for your Label. This is a solution:

[self.lblBadgeValue sizeToFit];
self.constraintWidthBadgeLabel.constant =  self.lblBadgeValue.frame.size.width;
[self.lblBadgeValue needsUpdateConstraints];
[self.lblBadgeValue layoutIfNeeded];

• Explain more:
• sizeToFit -> make label fit height, width with content of it.
• So in runtime you need to update constraint height, or width for label
• After that you need to say for compiler know that what need update constraint.
• And in the end you need to call layout if have change on constraint.
