I have just updated to XCode 9, and there are many "additional" warning about AutoLayout constraints that were not there before in XCode 8, such as "Trailing constraint is missing", "Leading constraint is missing", ...
Theoretically these warnings are correct, and can be fixed by adding more constraints, but sometime it's overkill to do so for all views.
Is there any way to turn off, or to customize when these warnings appear? I only want to turn off warnings that are introduced in XCode 9 like the ones above, not all the warnings, as warnings like conflicting constraints are useful and better to be kept.
