I have installed xcode 7 and run many apps on the same. But suddenly when i restart the xcode it hides the device header and run icons in top left bar.
Thanks in advance for help !
This is a exsisting bug with XCode 7 I see on our systems.
It happens when more than one project are open at a time.
The first Window will keep its bar, but all other will open without it. Sometimes hiding/showing the toolbar help, but that works only two times or so. Then a restart of XCode is the only cure.
Apparently you hid the toolbar. To reenable it: Select View -> Show Toolbar

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
Anyone can help me something goes wrong with me, I cant see my storyboard View, subview, imageview. All became white and its show error like on storyboard file
"An internal error occurred. Editing functionality may be limited."
I have open my project in xcode 8 and 8.1 beta latest xcode but both have same issue.
Main thing is that this is happening with all project not just one.
For example i am opening new project that is open in xcode 8 and i cant see that storeyboad file. Old project is working fine which are not open in xocde 8 i can see that project and open in xcode 7.3.1. but if i open that in xcode 8 and convert to xcode 8 compatible and this issue happen.
I have the same problem with Xcode.
I resolved it by disabling SIP (System Integrity Protection):
Press Command-R when start hold til logo and loading status appear
Open terminal
In terminal print: csrutil disable
Restart system
I have also faced this issue and resolve it by only follow these steps:-
Go to Xcode -> Preferences
Select Locations Tab
Click on Derived Data arrow.
Trash Derived Data Folder.
Restart System
Automatic Fixed this issue.
May this help you.
They inserted autolayout a few versions ago, exactly for this foreseeable reason. It's highly discouraged to use storyboards without autolayout, if you want to work with size classes, different devices with different screen resolutions, orientations, ecc.
My suggestion is revert the project to previous commit, reopen it with xcode7, add the needed constraint and reopen with xcode8 (you will still have problems, because of the many bugs of the new storyboard but they are mostly fixable).
Another option to keep working with in xcode8 it is to use a "freeform" simulated size from the Size inspector of the view controller and adapt the sizes to the old viewcontroller dimensions, but you will have to manage compatibility with all devices sizes programmatically, as i hope it is already being done. It doesn't anyway guarantee that everything works
There are some bugs in storyboard of xcode 8 so if you are not using autolayout then you should use xcode 7. now as you said in question that you are getting problem to open storyboard in older xcode (i.e. 7.x) that because once you open project in xcode 8 then it's change some configuration of storyboard which are not compatible with older xcodes.
So now for solution Open your project in xcode 8 -> open storyboard -> File inspector -> Under Interface builder document -> select xcode 7.x instead of latest xcode 8 from Open in
It will show popup something like Saving for Xcode 7.x will close your document and data for Xcode 8.0 features will be removed. Click Save and close the xcode 8 and open project in your older xcode (7.x) and you will able to open storyboard as it was before!!!
You can refer below screenshot,
Hopefully Apple will fix issue related storyboard and in newer version of xcode 8 you will able to switch project without messing up your UI! But right now there should be a workaround as i mentioned above! Try it!!
for me I just make all the views in storyboard size to inferred

This is driving me nuts.
My app was running normally and then I don't know what I did but any changes I now make in the storyboard/ IB/ Xibs etc are not updating when I run the app either on real device or simulator. For instance, I changed the textColor of UILabel but when I run the app, the old color still shows both on device or simulator. I am using Xcode Version 7.3.1.
Please help. Thanks
This solution had worked for me:
Just delete that storyboard in which changes are not reflecting and take new storyboard instead it will start reflecting changes.
When you have the simulator open.
Click and hold down your app icon
When you seen the icons shaking and "X" in their Top Left, Click to delete it
Do the same for any other App Icons you may have showing in the Simulator Home screen
In Simulator menu at top - Click "HardWare" -- "Home" to stop icons shaking
In same menu Click "HardWare" -- "Reboot" (Wait for this to complete)
Quit Simulator from its menu "Quit Simulator"
(nb: when using device to run app, I would delete it from app as well)
Then Go back to Xcode
click in to menu "Product" -- "Clean"
Quit Xcode and open up again
Run Simulator on the iPhone Simulator Size you just cleaned out (above)
I've tried to simulate the issue you're having but unable to, however, when I have any issues on running my apps, the above seems to work.
[ Sometimes Xcode can be a bit slow, so I tend to wait a few seconds to confirm it / Xcode has actioned it, as I sometimes used the keyboard too fast for it to keep up.]
Hope this helps!
Hopefully to save someone some frustration, I had this same problem and figured out that I must have accidentally hit Command+d while trying to copy something and duplicated the scene. The duplicate was laid perfectly over the original so I couldn't tell I was editing the duplicate instead of the actual scene linked to my navigation controller. I was so focused on the problem I didn't notice the new warning for an unreachable scene in my storyboard.
When my Main.storyboard was not saving (its file icon remained grey after clean+build), I found that running git add -u and git commit -m "//your comment" in my terminal would change the Main.storyboard file icon to yellow again (not grey)
Try removing all constraints from the changes you made and then reapply them. That is what worked for me.
I have attached a screenshot of the problem.
I am able to select the device using the product menu but there is no shortcut visible in the toolbar to select the device.
Go to View/Show Toolbar and click it.
Just Restart Xcode. Same problem i have faced Xcode Restart resolved the issue.
I've seen this before. The issue in my case was that the run destinations list would disappear if the window was too narrow. If you resize the window to be wider, it should pop back in.
I recently heard about this GUI view hierarchy in Xcode. And I have used it many times. But I sometimes when I run the app, the button is not there at all.
Can anyone please tell me when exactly will the button be visible when debugging??
Only iOS 8 or better targets (simulator or hardware) get the button . You won't see it for an iOS 7 target.
