In Xcode 7.3 the visual debugger no longer shows the light grey outline around each view, making it hard to see the different views. This is what I see (it is missing the grey outline):
This is what it used to show in Xcode 7.2 (it has the grey outline arounds views):
Any ideas why, something I need to turn back on, a bug maybe? I have tried toggling the options along the bottom of the visual debugger.
I am showing Wireframes and Contents and toggling constraints seem to be broken too!
Anyone else seeing this?
I looked at another Xcode and the lines were there, so assuming this is a bug, I reinstalled Xcode and it fixed itself.

I have updated by Xcode to Xcode 11 Beta and have updated the build settings from iOS 12.2 to iOS 13. Everything is working perfectly but the viewcontrollers in Storyboard appear black. The components of the viewcontrollers are present but it is difficult to preview due to the black screens
Had this same issue, eventually tracked it down by cut-pasting elements from the black screen to a brand new view controller and see which ones cause the new one to have the same error, or caused the old one to render.
After fixing it, the diff ended up being a background image on a specific UIButton.
I found that after updating to Xcode 11 if one element has an issue, it breaks the whole storyboard like your screenshot.
I had this issue last night. My UITableView was expanding too far out of the screen on the right hand side. I dragged it back into the bounds of the UIViewController parent and updated the right hand side constraint to be 0.
So check if anything goes beyond the UIViewController boundary that shouldn't.
In Xcode 12.4
After trying lots of thing, finally i resolved my issue
First close your project.
just goto finder -> Application -> Xcode -> get info -> uncheck open using Rosetta
Now, simply open your project.
Just delete any constrain in that viewcontroller and then undo the change.
Check the values for the cell heights. In opening an older project, the row height (in the TableView itself) was 0. Changing it to a positive value or deleting the value (so it defaults to automatic) fixed the issue for me.
I had the same issue, here are the steps I followed.
Clear constraints, for my case the source was from UITableView, and make sure constraints are attached to safearea not superview.
From the toolbar on the top, go to Editor > Canvas > Layout Rectangle. It is very important to repeat this step 3 times.
Once finished, quit XCode and reopen it again and everything should be fixed. I've noticed this happens when I'm switching views for different devices 8, 11, 4s.
I don't know exactly what the problem was, but I was able to solve it with the following steps.
Run 'pod install' to install all cocoapods dependencies
In Xcode: Product -> Clean Build Folder
Restart Xcode and run the project
I'm using Xcode 9 Version 9.1 (9B55). There is something strange happening in a storyboard. Some of my views are are messed up, and I don't know what is the reason.
It looks like this:
EDITED
However, all my constraints are set right, and when I run the project on different simulators and on a physical device, everything looks fine. Here how it looks on a simulator/physical device:
I don't know what is the reason for this kind of behaviour but it makes impossible to work in a storyboard. I think, this problem has appeared quite recently. Sometimes, after reloading the Xcode, views again look fine, but when I start working with storyboard (adding new views, changing constraints or even just tapping on a constraint to see its constant), they again become messed up. Does anybody have this kind of issue, and how this could be solved?
After closing and opening Storyboard, the issue goes away! I think it's just an issue in x-code 9.
As a quick fix, try changing the spacing on one of your stack views instead of closing and reopening Xcode. Toggling the spacing brings back the views in my case.
I have this weird issue in interface builder. When I place a UILabel in a UIView and drag it to the leading/trailing end of its superview I'm not seeing any blue line (which is usually 8 points from the edge).
I tried to find if there's an option in Editor menu to reset it but no luck.
Anyone faced the same issue and resolved it?
Here we go :]
The problem is that Xcode is an IDE with quite a lot of bugs. They are usually very small, but sometimes very annoying.
I always restart Xcode from time to time.
And when something isn't working, as it should, restart of Xcode solves this problem in 99% of cases.
So, try to restart Xcode. Hope it will help.
Solved it by enabling Snap to Guides from Editor menu.
I recently looked at my app's main.storyboard and realized that there is a big, blue, rectangular box covering half of some of my viewcontrollers (image is pasted here). Only the UIViewControllers connected to the UITabBarController are affected. I did not even realize that this had happened, despite having moved to xCode7 a while ago. It is a bit annoying since dropping any UI element into the view controller causes that element to 'go behind' this blue region and so I can't see them. It is not that the default color is set to blue or anything; it is not a clickable object to even set display parameters to. Anybody have any ideas how to fix this... or even what it is?
Edit: This is not a problem singular to this particular XCode project. Any new project I create and insert a TabBarViewController has this issue.
Edit 2: Problem disappeared then came back. Posted the problem (which persists on for even a brand new xcode project with tab bar view controller). It is at https://github.com/AlekPiasecki/XcodeProblems
Edit 3: To anybody that has the same issue: This is almost certainly due to hardware. I have the latest version of XCode (the XCode 8 beta) and OS Sierra installed on my computer. The github post continues to have the same issue for me, but it appears fine on computers which do not have these betas installed. As far as fixing the problem now that I am stuck with these Xcode and OS versions... I still have no idea.
Adding an image to the TabBarViewController fixes this issue. The blue box goes into whatever size the image is, so making the image really small (like, say, a pixel) shrinks the blue box so that is invisible (essentially). This works in practice as a solution, but don't know how to truly permanently get rid of it.
This is a Xcode error that will be fixed in 8.2 release.
This is the Apple official note about this problem.

In xcode 5 with iOS7 target project the size inspector in storyboard is not work. When I have one element selected like a button, view or anything else and I go to size inspector of storyboard all is empty showing nothing.
I tried restarting Xcode, unchecking Autolayout, uninstalling an reinstall Xcode and nothing. This problem persists.
Is very strange that on other Macs I open the project and size inspector works correctly then not is a project issue.
If someone have the same problem and solve it. Please tell me how can I fix.
Thanks.
The answer that helped me is here. MouseOver "View" shows Button "Show".
Reinstall of MAC OS X solves this issue 100%. In inspector size. But in size inspector you've probably noticed the "Show"|"Hide" watermark an the right top corner of panel. I agree that these hidden invisible buttons in IB is not the best solution in terms of UX. But Apple knows better :)
