This warning happens in Xcode 6.1. Anyone have ideas what does this warning mean and what will happen with it? Many thanks!
Below is a screenshot with the warnings opened in source code"
How to find which constraint causes the warning? Xcode does not tell you which constraint is the problem.
This warning can be annoying and happens as of Xcode 6.1.1. The main problem is that you can not easily find the referenced constraint by clicking on the warning. I guess this is a bug and will get fixed sooner or later.
However, in the meantime you can use this little workaround:

Note that for Xcode of 5/2016, annoyingly you have to quit and restart Xcode to clear this warning in some cases.
Note that confusingly, the same error can be caused by an unrelated problem (this appears to be an Apple bug or poor use of error language): if you have IBInspectable items, and happen to rename them in your Swift files. Xcode does not delete the old-name UserDefinedRuntimeAttributes for you. Simply click to "Identity Inspector" (item 3 on right panel) and delete the dud items.
This message is triggered when you have deactivated a view in your storyboard, but didn't deactivate the constraints based on that view.
For example, you deactivated a button, but you still have some constraints linked to that button. It may be an intrinsic constraint like height or width, or a relative constraint like the distance from another view.
You have to turn off each of the constraints referencing the view, and you have to do it manually. Xcode is being overconservative here and won't do it for you.
This solution works for me.
Because I copied several items from the project I developed in Xcode 5 into Xcode 6, and the storyboard in Xcode 6 supports multiple layouts, for every constraint, I need to install it in the current configuration.
For example, I am using "Compact Width | Regular Height", for the constraint I need to set like below:
After I checked and set all the hundreds of constraints in my projects, clean and build, the warnings finally disappear.
Just wanted to add my case how this Error happened for me: In my case, I wanted to delete a Textfield with "Cmd+Backspace". I did this directly in the Scene-Builder Tree-View:
You can see that the snooze Field is grayed out.
So that was easily discovered for me. You can than simply really delete the Field by selecting:
Edit-Delete from the Menu
Surprisingly - this really deletes the field (including the constraints). Maybe this helps someone to easily find the cause of this annoying Warning...
Expanded Explanation
Nothing wrong with the other answers. I just wanted to draw attention to the wording in the original warning and to identify a couple of use-cases where this can show up in one's workflow.
Constraint referencing items turned off in current configuration.
Meaning that some item (usually a control or custom view that is normally visible) referenced in one or more constraints is turned off (disabled or has the checkbox "installed" unchecked). If for example you decide that you want to move a control or view in your storyboard outside of the main view (or you may see sometimes when doing something interesting in size classes) then you may see this warning if the control has constraints attached to it.
Along with the recommended solution:
Turn off this constraint in the current configuration.
Two Approaches to Fix
Document Outline
Visually you can open the Document Outline in your storyboard and look for the grayed out Constraints that reference your control/view sitting outside of the main view (widen the outline, click the constraint, and view the attributes inspector, mouse down to review fast). Then remove the constraint from this context (size class). For example, in my case I am just holding the control until I decide later where to present it, so I chose to delete completely the offending constraint until later. But in a size class I would just uninstall the constraint from the current context using the installed checkbox in the attributes inspector.
Log Navigator/Find Tool
One can also continue to use the Log Navigator to find the problem control via the unique identifier given to each object on the storyboard. In the log it would be just before the yellow highlighted text and typically takes the form as seen in my example above: jvj-mY-DHf
Using the identifier one can then use the find tool in Xcode to locate and delete (completely) or uninstall (for the current context) the offending constraint.
If you're fond of Xml and its simplicity you can also just open up the Storyboard as Source Code and find the offending unique identifier and delete the appropriate block of xml.
One of the reasons this could happen is because you selected a size class not compatible with your constraints (wAny hAny is a common case). In such case, just select a different size class in Interface Builder and you are done.
For me, it happens if I set an object a new contraint to object (not view) with "Constraint to margins" option not ticked. Problem solved with tick the option (which is default).
What worked for me (and I have no idea why) is to turn "Use Trait Variations" off, then perform a clean, then turn them back on. The next build had no warnings.
To turn off "Use Trait Variations" simply select your storyboard in the Project Navigator and then select File Inspector.
Then just deselect "Use Trait Variations", perform clean by pressing Shift-CMD K, and then turn trait variations back on if you want to use them.
I thought it was a persisting constraint due to the other answer, however it was due to an 'outlet' I still had for an item I deleted before. What to do is:
Worst case scenario you delete all your outlets and just hook them up again. Case solved!
As mentioned and well guided in @BadCat's answer, I followed down the steps and just one more step I dared to take!
Steps to carry after last step of BadCats answer:
Step 1:
I selected the constraint in the Interface Builder and then keeping that on mind what it is it for and then deleted it.
Step 2
Build the XCode Project and it will show you may be the number of Warnings are increased. That's because you have deleted a constraint that it needs to compile well. So, go to 3rd Step!
Step 3
Re-add the constraint which you kept in mind(the one you deleted). And then re-build it again!
For Me the warnings went away just by doing this! I guess this will work out for some people!
Cause:
As I could understand the problem which caused to this warning was, I had a Label connected to an IBOutlet, but its name was starting with a capital letter. So I renamed it with a simple letter in the ViewController and came to change it in the IB. I removed past IBOutlet and went to connect it to the newly renamed property name and connected. Then I noticed there is a new warning come up.
First I tried the following answer too in this thread, but it didn't help!
Cheers!
My case is choose label, then click control + X, it will be disable, but I don't do any thing with it. When I build, it will show warning. Solution: remove label or remove chosen control + X for label.
I delete all those UI elements including their constraints, and add them all again, those warnings just disappear. Anyway this is a worst but useful way to solve this.
I had the problem on a stack view. Deleting the constraints and re-adding them did not help. Cleaning and rebuilding did not help.
For me, the solution was to create a completely new stack view object.
Then move all elements from the old stack view into the new stack view.
Deleting the old stack view fixed the problem.
