I have been using the latest Xcode for weeks now with no issues. Today I tried to launch Xcode and was met with a bouncing icon which ultimately got no further.
So I restarted my Mac and tried again, this time with success, I got as far as the launch screen
Now what I have is I try to open the project that I was using yesterday (I have tried other projects) and the launch screen disappears.... and nothing happens, if I click Xcode's icon in the launch bar (along the bottom) the launch screen reappears.
Xcode is not closing so it's not crashing as far as I can tell
every so often it does give me the spinning circle and then crash.
I have also reinstalled Xcode but nothing has changed
Macbook air 2017 -
macOS Big Sur (11.2.3) -
Xcode 12.4 (12d4e)
Incase anybody else experiences this issue I will answer this question here.
This appears to be a bug with the Xcode launch screen for this version of Xcode.
My solution was to simply click the checkbox that says "show this window when Xcode launches" to turn that off
relaunch Xcode and open my project from the file menu.
Thanks matt for the suggestion :)

My code was working fine (showing UI properly) when I had Xcode 9 and I removed it from the application folder (could not update as it had installed using another apple id) and reinstall the Xcode 10 from the Appstore.
Now Xcode storyboard not showing any added UI elements colors or anything and I removed Xcode 10 and installed Xcode 9 again but problem remains same.
UI screen shot of storyboard.
I tried removing Xcode in this way:
/Applications/Xcode.app
/Library/Preferences/com.apple.dt.Xcode.plist
~/Library/Preferences/com.apple.dt.Xcode.plist
~/Library/Caches/com.apple.dt.Xcode
~/Library/Application Support/Xcode
~/Library/Developer/Xcode
~/Library/Developer/CoreSimulator
Then I tried installing macOs Mojave and install XCode 10 again from the Appstore. Issue still remains. I tried cleaning derived data, xuserdata and everything.
Try cleaning your project using "Command + K"
and run your project again!
Hope it works!
I encountered the same issue that you are facing in my case i had xCode 10.0 installed and everything was working fine. As soon as I installed version 10.1 I faced the same issue that you're facing but the good thing was i had xCode 10.0 installed at the same time so I switched back and everything was working fine.
From my point of view my system(Mac-mini mid 2011) was lacking hardware specification that was required for xCode 10.1 also had very low graphic processor in my mac mini. If you install the same version in a MacBook or any other system having higher specification you'll face the issue. I hope that helps.
I was stuck on this all day. One of my coworkers suggested removing occurrences of IB_DESIGNABLE & #IBDesignable. This fixed the issue for me. It still lags sometimes but doesn’t go invisible anymore.
If you have multiple xib files then just try to switch between or Try moving to launchScreen storyboard and then switch to main storyboard. I think this is just loading issue.
Reinstall Xcode. That worked for me.
Click on library button(Circular Button) which is left to hamburger sign(Top Bar Right Side). Elements will be popup on your screen then you can choose elements.
try
xcrun simctl erase all
it helped me with the same problem
I sometimes get a dialog in Xcode which states "Simulator in use." Restarting Xcode didn't help.
I have no Simulator Icon in the Taskbar to quit it and I have no running Simulator.
Is there any solution without rebooting?
I know some of these points to not adress your specific issue since you wrote restarting Xcode would not help you but I'll try to provide a full list of possible fixes for people who might stumble upon this one day.
Is the "Stop" Button in the left corner of Xcode still clickable ? ==> Click It
Try to reset contents & settings of iOS Simulator
Clean Build & Clean Project
Quit iOS Simulator (look at the Activity Monitor if there is still something running)
Restart Xcode
Restart Mac
This is all I can think of. For me most of the times I can resolve it by just restarting Xcode. As you wrote this does not work for you so maybe some of the other points of my list will help you.
Normally this happens when you terminate the iOS Simulator but not the debug session itself, which is why most of the times the "Stop" button in the left corner is clickable most of the times...
This dialog (and the state that triggers it) comes entirely from Xcode and not the simulator itself. This dialog will present itself if Xcode is already using the simulator from another workspace. For example, if you have three projects open at the same time and you do a Build&Run (eg: click "play") in one of them, you will get this dialog if you do a Build&Run in one of the other projects.
I have installed Xcode 4.3 version. I can't click on any button of the Xcode bar, because Xcode freeze at startup, and if i move the cursor on the bar, i have only the loading cursor available. So i can't click on Window Tab to restore the Welcome Window, and i can't open a new project.
It seems that Xcode is not loading any project, and maybe it is the problem it has not found any project, and it continues to search anyway. If I try to launch an existing project, Xcode tries to open it, but the result is always the blank window with "No Editor".
Please help me to come out from this issue or any one please tell me how can I remove all the logs, settings and back up files of Xcode
Thanks in Advance
I solved the problem :) Simply download and install the latest version of iTunes, it's fixed :) Now i can work with Xcode. I dont know whats the connection between Xcode and iTunes. Cheers....
I have run into a rather annoying bug in Xcode 4.3.2.
If you run a process from within Xcode, then stop the simulator directly (outside of Xcode), Xcode still shows the process as running and effectively disables any further interaction with the simulator.
I can't stop the process from within Xcode (no response), and I can't start a new process either as Xcode sees the simulator as being in use. Shutting down the simulator does not notify Xcode either, so I have no option but to shut down Xcode and open it up again But even that does't work as Xcode hangs whilst trying to shut down the process too! So I have to force quit Xcode!
Has anyone found a way round this? I realise I should now only operate the simulator from within Xcode, but I am used to being able to operate the simulator independently.
thanks
I was having similar issues with Xcode 4.3.2. I fixed them by doing the following:
Launch Xcode.
Close any open projects.
Open Organizer.
Delete project form left panel using the gear icon on the bottom left. Select "Remove from Organizer...". This clears all the data about your project that Xcode has cached (indexes, DerivedData, Snapshots, etc.).
5). Re-open project.
Since doing this, my Xcode hanging issues have disappeared.
Here are the steps I follow when this happens:
Start the simulator if it isn’t already running
Choose the option “Reset Content and Settings…” from the iOS Simulator menu
Clean and rebuild the project
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! :)
