I set the constraints of layout properly and also tested it on every device. But the next time I open the project, Xcode just ruined the constraints totally.
How did this happen?
May be the project has a problem and for some reason it is not saving the changes. I have indeed put this solution on my troubleshooting book about Xcode from Apress (shameless advertising... 😃). I have seen this before.
Backup your project and try this:
Quit Xcode
Using finder, right click on the .xcodeproj file of your project and select Show Package Contents.
delete everything from that except the file project.pbxproj.
open the project again fix the constraints and see if the changes are saved the next time you open Xcode.
You did not specify you Xcode version, but my own experiences with code, that is developed using Xcode 8 Beta 1 to Beta 6: The problem may be caused by bug in XCode.
The explanation, if you use Xcode 8 Beta, could be:
New Xcode offers new storyboard-display logic, that shows different difficulties still in Beta 6
After fixing both constraints and frames automatically / manually, warnings come back again after reopening project
This problem moves from Xcode Beta 2 to Beta 6 after my own researches
Let's give Apple a little more time to fix the issues and let's wait until Apple releases GM Seed. It's only beta though
I recently updated my Mac software to OS X El Capitan. Xcode started crashing repeatedly! Whenever I tried to create a new file, it crashed. So, I updated it to Xcode 7. Now, whenever I create a new file, the beach ball appears and the application stops responding. I end up force quitting. This happens with every project. Whenever I click on any file, the same happens. I really need an answer to this as soon as possible because I am partly dependent on Xcode.
I am trying to convert a view from the storyboard to nib file, someTimes when I cut a view from the storyboard and paste it to the xib file, xcode stuck ? What should I do ?
I am using xcode 6
answer:
I immigrate to xcode 5 and it works fine
Xcode 6 is in beta. If you can determine a reproducible test case, please file a bug report, and attach the files that make it hang or crash.
My installation of XCode 5 has started crashing with the message pasted below in pastebin link.
It's been keeping me trying to figure it out for the past 2 hours.
So far I tried:
1) Reinstall XCode
2) Force it not to open latest applications.
I am at a total loss.

I recently installed Xcode and after closing out of the first launch (because I realized I had more configuring to do). I cannot get it to re-launch. The icon will come up, but no program will show up. I do not get an error, and I am launching from the /Developer folder (not /Applications). I have tried re-installing/restarting multiple times to no avail. I have the latest version, and I am running Snow Leopard (10.6.6).
The icon will come up, but no program will show up.
Are you new to OS X? It sounds like you are describing the way OS X apps normally start up. By default, Xcode pops up a window with a list of most recent projects, but you can switch this off. It doesn't mean that Xcode isn't running, it just means you don't have any Xcode windows open. You can still select any of the usual menu items to start new projects, open existing projects, etc.
The answer to this problem is I believe easily sorted. Once you open X code and all you get is the menu bar at the top, go to Window, Welcome to x Code, then check the box bottom left hand corner of that screen 'Show this window when Xcode launches'
Job done ! Now every time you hit the Xcode icon where ever it is the welcome screen will open and from there you can proceed into the program.
Probably not your problem, but I had issues starting xcode with it trying to load up the last project I was working on. It would just hang and I had to force quit it.
In the end I deleted these directories:
project.xcworkspace/
xcuserdata/
and next time I tried to restart xcode it started fine.
Please go project folder and right click ."xcworkspace" and open "show package contents"-> xcuserdata and delete user folder and then relaunch.
In my case I launched XCode 6 (beta 7) on my MacBook Pro Mid 2010, and I had to wait for ~10minutes for anything to happen. I didn't see icon in dock, or even menu bar - just a reference in Force Quit Applications menu. After those 10 minutes classic alert with "You have downloaded Xcode from internet..." title appeared and then i had to wait another 5 minutes for another progress (installation of additional components).In overall it took Xcode 6 ~25 minutes to start.
So... Patience! :)
