My view looks good across all devices. However, I am getting warnings stating that some of my labels are ambiguous. Should I worry about this and try to fix it?

Could you post the warning here. It is best to always remove warnings. A warning basically notes that something is probably going to act weird or go wrong, but it won't normally crash the app. So even though it runs fine with the warning, it still may look or act poorly on a device you are not testing for.

If you open the "assistant editor" (top right 2 circles overlapping), the breadcrumb for the right side can be switched to preview. You can add new devices sizes with the "+" in the bottom left of that window. This will allow you to see how your constraints will react to different device sizes.

Yea Ive got it to look good on all device sizes already. Ive got 6 warnings. One says something like horizontal view ambiguous. I mean of course its ambiguous, I want my labels to be able to space out and shrink with the varying device sizes.

You will need to attach it to the bottom or to another view that is attached to the bottom. If you have it attached to another view and they both don't have heights, then it becomes ambiguous, since it can't figure how much to spilt up the difference between the two view heights. So either you have to have the heights to equal each other, or you need to set a ratio between the two heights view1.height > view2.height ratio 1:3 (view1 will be 1 / 3 height of view2).
