UITableViewCell没有扩展到适合UILabel的高度，我在做什么错？

Question

What I want is my UITableViewCell to expand/shrink based on the height of the UILabel inside.

I have tried just about every solution I could find and it's not working. Maybe I have some setting that's preventing it.

Here is a screenshot of the UITableViewCell settings:

For the UILabel inside, Lines is set to 0 and Line Break to Word Wrap .

In the UIViewController where I'm showing the table view, I am setting this in viewDidLoad() :

tableView.rowHeight = UITableView.automaticDimension
tableView.estimatedRowHeight = 44
tableView.reloadData()

And in cellForRowAt after dequeuing the cell I'm doing (instructionText being the UILabel):

cell.instructionText.numberOfLines = 0

I've seen this in many tutorials and it works, why not for these cells? The content comes out like this:

This is driving me crazy! Thanks for any help!

EDIT: Here are the UILabel settings:
