How can I align the stackview according to the content of the first label on storyboard ?

CodePudding user response：

Make sure the horizontal Content Hugging Priority of your left label has a higher value than the one on the right. The exact values don't matter, but the left one must be at least 1 higher than the one on the right. For example, use "Default High (750)" on the left and "Default Low (250)" on the right.

Select the left label and then from size inspector change horizontal Content Hugging Priority = 1000
