Xcode font scale (auto-shrink) not working properly

Question

I have a label, in which is a main feature of the content. I therefore have it set to autoshrink.

The problem is that when I run it on some of the smaller devices, the text is shifted downwards horrendously based on the label box.

How do I fix this?

Edit: This shows the problem that the labels do not fill the container after fixing the autoshrink shifting problem

check if number of lines is 1 and you have setted properly your constraints — Reinier Melian, Feb 18 '18 at 16:25
1 if you want to font scale works, well 1 or any fixed number, if is 0 the label grows in size and the font don't scale — Reinier Melian, Feb 18 '18 at 16:28
Thanks. You have prompted me to make it work. Having 0 lines actually makes font-scale work. Thanks! If you write it as a proper answer I will rate is as right. — D-A UK, Feb 18 '18 at 16:28
Apart from that the fact that the label text does not 100% expand fully to the bounds of the container. - Any way to fix this easily? — D-A UK, Feb 18 '18 at 16:40
you need to use your cell with automaticDimension I think that is the main issue — Reinier Melian, Feb 18 '18 at 16:41

Yes. What you did fixed the shifting. One problem, however, is that the labels do not fill the container. A demonstration shows this using background colours. I have put the photo in the original post. — D-A UK, Feb 18 '18 at 16:54
Thank you. I really appreciate all you have done and are doing to help me :) — D-A UK, Feb 18 '18 at 17:10
check my updated answer, if you need the label fill the container vertically you need to adjust the constraints — Reinier Melian, Feb 18 '18 at 17:56

Your main issue is that your number of lines for those UILabels is fixed, and you need numberOfLines = 0 to allow that UILabel frame size grow as it needs to, using UITableViewAutomaticDimension in your Cell

This is misleading. Setting `numberOfLines` to 0 will *prevent* autoshrink entirely. – Grant Palmer Feb 25 '19 at 22:44
@GrantPalmer you are right i was thinking that the OP wants to grow the cell instead of shrink the Label that's why – Reinier Melian Feb 26 '19 at 07:10
This answer certainly helped me. I have constraints controlling the label size, and Autoshrink set to 'Minimum Font Scale'. Curiously, setting the number of Lines to any number *other* than 1 works—0, 2, 3, whatever. As long as it's *not* 1, the font scales down to fit the label size. How odd! – Kal Jun 25 '19 at 03:23

For auto shrink in Storyboard attribute inspector

A. Select Automatic Adjust Font

B. Change Auto shrink to minimum font scale/size.

NOTE: In some case try to test with line breaking mode to get working state.
