Currently I am able to update the user's tag if changed in Firebase Database and have it appear in the proper array when the app is restarted.

问题 So I have made custom view ExpressionView for visualizing mathematical expression. Every part of expression is UILabel holding one number or operation, and labels are aligned inside the ExpressionView in right-justified rows. I expect ExpressionView to have width defined by autolayout constraints from outside, but height should be intrinsic, depending on how many rows of labels I will have to make for a given width.
