Answer 1

You'll want to do this:

myLabel.sizeToFit()

As seen here: https://developer.apple.com/documentation/uikit/uiview/1622630-sizetofit

This will update the label's frame to fit the content. You can then place it or make any edits after this that you want.

how would I go about spacing the content of the label so that it automatically changes rows instead of just outputting a long string of text onto one line? – Involuted

This workes well together with "myLabel.numberOfLines = 0" – Gathers

Answer 2

sizeToFit() doesn't always work so you should use this:

myLabel.adjustsFontSizeToFitWidth = true
myLabel.minimumScaleFactor = 0.5
myLabel.numberOfLines = 1

Or if you don't have limit lines you can do this:

myLabel.numberOfLines = 0

Splint

you should add myLabel.numberOfLines = 1 to your answer, so the minimumScaleFactor works – Contraceptive

Answer 3

Here's the step that work in mine:

1. Set width constraint to the label, then click the constraint.
2. Select Size Inspector.
3. Set the relation to less than or equal, and set max width.

Answer 4

myLabelName.numberOfLines = 0

** This worked for me ( To put Same Text Size, this will put text to a new line on width size reduced) **

We can also use,

myLabelName.adjustsFontSizeToFitWidth = true myLabelName.minimumScaleFactor = 0.5

** This will reduce size of the text on width size reduced. **

Answer 6

Many of the above responses work well, but you have to consider the UILabel's constraints.

For example, if you ensure that the UILabel will have leadingAnchor and trailingAnchor Constraints with its superview, you can use the .numberOfLines = 0 property, and the height content size will be set automatically.

Answer 7

I had a somewhat different case unrelated to sizeToFit(). My label had adjustFontSizeToFitWidth = true and it was oddly adjusting the font size when it did not need to and leaving the label with extra padding at the end.

Simple fix:

myLabel.adjustsFontSizeToFitWidth = false
