contraints in tableviewcell seem to be ignored - swift

Question

I can't get these sliders to line up, Im not sure why.
here's my storyboard ...that trailing constraint is clearly being ignored. What am I doing wrong?
edit: for matt:
I deleted all constraints
and control-dragged two of them, which should have been sufficient: the trailing: 14 and the center Y (now on superview, the rhs being label was in error). there is no "remove at runtime" on any drawn constraints.
the flags are visible but there's no indication of what they mean (the size inspector unhelpfully says only "has ambiguous constraint").
edit #2
Based on input here and in swift discord, Here's an example of the view with changes applied:
and here is the relevant xml of that storyboard:
<tableViewCell clipsSubviews="YES" userInteractionEnabled="NO" contentMode="scaleToFill" restorationIdentifier="RootAppCell" preservesSuperviewLayoutMargins="YES" selectionStyle="none" indentationWidth="10" reuseIdentifier="RootAppCell" id="PDl-Cx-SrR" customClass="RootAppCell" customModule="Assignment_5">
<rect key="frame" x="0.0" y="28" width="343" height="44"/>
<autoresizingMask key="autoresizingMask"/>
<tableViewCellContentView key="contentView" opaque="NO" clipsSubviews="YES" multipleTouchEnabled="YES" contentMode="center" preservesSuperviewLayoutMargins="YES" insetsLayoutMarginsFromSafeArea="NO" tableViewCell="PDl-Cx-SrR" id="EHS-uv-XgI" customClass="RootAppCell" customModule="Assignment_5">

Answer 1

If you are unclear on which constraints that are conflicting, take a look at the console output when you load the screen, you should be able to see something that looks similar to this
(
"<NSLayoutConstraint:0x6199cd0 UIButton:0x7fbbf90.width == 0 (active)>",
"<NSLayoutConstraint:0x6998ec0 H:|-(15)-[UILabel:0x6ce60] (active, names: '|':UIButton:0x7fbbf90 )>",
"<NSLayoutConstraint:0x6199000 H:[UILabel:0x6ce60]-(15)-| (active, names: '|':UIButton:0x7fbbf90 )>"
)
And to help even further, you can use this web page to paste that section and it will at least tell you which constraints that are conflicting in your code..

Table view cells can be tricky since they will get additional constraints based on for instance what you have set as row height of the cell etc.
Hope this helps the debugging

Answer 2

This is what I tried, and worked well for me:
Add Constraints:
Leading of the UILabel from superView is 15.
Center Y of UILabel is equal to superView's center Y.
Bottom of UIView (divider view) from superView is 0
Trailing of UIView (divider view) from superView is 0
Leading of UIView (divider view) from superView is 0
Horizontal space between UILabel and UISwitch is 5.
Center Y of UISwitch is equal to superView's center Y.
Trailing of the UISwitch from the superview is 10.
One more extra constraint needed for UIView (divider view) that is Height of the view is 1.
Here is the output:
Hope this will help you!!
