I am having issues with errors in Xcode. I have purposely set errors in my code just so the errors show up, but they only appear for 5 seconds then disappear. Which is making debugging extremely difficult. Is this a bug in Xcode's lates release?
As per GreyFox93's answer here:
I found that executing Xcode with Rosetta avoid that bug to occur. Maybe we loose a bit of performance but it's much more convenient to debug
In your Application folder, find Xcode, right click on it, then select "Show info". Here check the "Open with Rosetta" box. Restart Xcode if it was already opened.
Everything works great again on my side
It is a bug with Xcode 14. Just use Xcode 13.4.1.
From "boywhocodes" I used his suggestion which worked at once for me:
Cleaning Derived Data folder worked for me : Go to Xcode -> Settings -> Locations -> Derived Data -> Click on the right arrow icon Delete the Derived data folder and run again.
If I open IntelliJ IDEA and try and import any project or open any folder containing a project, nothing happens, I'm just returned to this screen.
Earlier on, before I moved my project files around, I tried to set a new JDK for a project and i clicked add SDK and then selected Java 12 home and again it returned to the screen without adding anything.
Is there some permission I need to grant to IntelliJ Idea?
Seems to have started since installing MacOS Catalina.
It's a known issue specific to the recent macOS Catalina update. Please follow YouTrack ticket for updates.
You can also help by providing the following information in YouTrack:
Open the file chooser, select a directory (but don't open it yet), take a screenshot, then open a directory; then attach idea.log and the screenshot (a path to a project and a time of the operation are needed, too, but they should be guessable from the screenshot).
As a workaround until this issue is resolved you can add -Dide.mac.file.chooser.native=false in Help | Edit Custom VM Options and restart the IDE.
Mac OS, Mojave or Catalina,
Exit intellij first,
Apple menu > System Preferences, click Security & Privacy, then click Privacy.
Click the lock , then enter your administrator password.
From the list of items on the left, select Full Disk Access.
Add Intellij(or other whatever app having this problem) to the apps allowed full-disk access by using the add button.
Lock and try again.
Hope this will help.
Ref from apple support of other things, but I tried, it works!
I can temporarily open things by dragging a folder to that window it seems, but its' not ideal.
Faced the same problem after the (PyCharm) update. Workaround: Go back to the old version.

Why "Add Documentation" is disabled in Xcode 8.2? How can I enable it?
This issue seems to appear randomly for myself as well. The only surefire way I've found to re-enable it is to run
sudo /usr/libexec/xpccachectl
in the terminal and restart my computer.
For the making it enable you need to select code first like following gif and you can add documentation based on selection.
It's ridiculous that it still happens even with Xcode 10.1. And it have a ridiculous solution:
Exit Xcode, then rename Xcode.app to something else like Xcode1.app, then back to Xcode.app. For Appstore version you will be asked for admin password.
I'm having issues with Xcode being quite unreliable when using the keyboard shortcut to comment or uncomment code ⌘+/. I can't seem to find a real pattern as to when it breaks, but it usually happens after building and running my code on the simulator. It will not work again until I edit something in any one of my code files. Even if I switch to another file in the main view, commenting via shortcut does not work. Other keyboard shortcuts, such as indenting ⌘+[ continue to work just fine.
Do other people have this issue, and if so, have you found a solution? I know it seems like a small complaint, but when running and then quickly trying to comment out a block of code to check the effect, it's a bit of an inconvenience.
I am using Xcode 6.1 (6A1052d) on OXS Yosemite 10.10 (14A389) and developing in Objective-C for iOS if that matters.
For an Xcode 8, solution is
sudo /usr/libexec/xpccachectl
and restart your computer.
Hit ⌘+] once and then ⌘+/ will start working again.
You can hit ⌘+[ to undo the indentation effect.
Update:
Please note- This solution was provided prior to Xcode 8 launch so it may not work for everyone. If you are still facing problem, kindly refer to #CryingHippo's answer instead of downvoting.
I have done this numerous times with Xcode 8. Latest being Xcode 10.1 where I would just quit Xcode and go to Applications and rename Xcode to something else, e.g. Xcode 2, launch it, quit again and rename back. It starts working after that. No Mac restart or Terminal commands required.
It still works as of Xcode 10.1. I cannot believe Apple still hasn't fixed it properly.
None of the above solutions worked for me with Xcode 8.0 (final). If you also have Xcode 8.1 beta installed like I do, try this: simply rename /Applications/Xcode-beta.app to something else, then restart Xcode 8. Oddly enough, that did the trick.
Oscahie's answer actually works for non-beta versions of Xcode as well. Here are the steps to follow, based on Sam's comment:
Close Xcode
In the Application folder, rename Xcode.app (or similar) to Xcode2.app. You might need to type in your password.
Open Xcode, then close it.
Rename Xcode2.app back to what it was before.
(Optional) Spend 5 minutes wondering why this worked.
No need to reboot!
I didn't have to do any of the above. A simple reboot fixed it.
A simple workaround works good for me with following steps:
Comment any line i.e. simply add "//" in front of a line.
Press Command + "/" and it starts working.
It might help someone.
In my code I had this sequence:
/*" BLABLA MY COMMENTS */
All the code under this was not "commentable".
Removed the " and it was ok !
Hope it helps!
I just had the same issue after setting up a new Mac with Xcode 10.1 using the German keyboard layout.
The solution was to disable the Keyboard shortcut in system settings for the help menu.
System settings > Keyboard > Shortcuts > App shortcuts.
There was a shortcut for all apps to show the help menu.
If you have that, click the checkbox to disable it
I am using Xcode 8.1 (not beta) and I had the same problem, not able to cmd+\ to comment. Restart Xcode not working for me but RESTART my Mac SOLVED the problem without a need to remove cache.
I had this problem in Xcode 8.0. Even though I already move Xcode 8.1-beta somewhere else (It's at Application/Xcode otherversions/Xcode 8.1-beta.app). I have to delete it to the trash, restart Xcode 8.0, and cmd+/ somehow works again.
Just quit xcode completely and restart. Worked for xcode 8.2
I was also facing this issue, when having multiple Xcode installed.
In which Xcode version you are you facing this problem, to solve this, the Xcode should be in the Application Folder. If it resides in the subfolder than move it to the Application folder directly.
I found a pattern where toggle comments do not work.
In fact, uncomment works, but comment don't, from keyboard as well as from the Editor menu.
This happens in a specific file, suggesting there is something in text that prevents from working.
I tested on XCode 10.1ß and on XCode10.2, on different machines.
Text before this line can be commented, text after cannot (I kept text exactly as is)
let alert = UIAlertController(title: "" /*"Teste texte"*/, message: "Love\nWe'll recommend more for you" /* Entrez des chiffres"*/, preferredStyle: .alert)
It appears that the /* … */ inside the UIAlertController() is the cause.
If I suppress both comments inside, everything works OK.
I filed a bug report. # 49907361
Nothing above worked, even after trying multiple times.
Just reinstalled new xcode using AppStore app, previously I installed xcode after downloading from
developer.apple.com/downloads. that is .xip file
Wait for new update and install.
Another reason may be that xcode isn't in Application directory.
I recently upgraded to Xcode 4.0.1 from the last version of Xcode 3x (not sure which). Install went fine and I can open and view all my old .xcodeproj files without problems. All except one!
The error I get inside Xcode is
"The file "GCSCalculator.xcodeproj" couldn't be opened because you don't have permission to view it. To view or change permissions, select the item in the Finder and choose File > Get info."
Obviously I've checked that and the permissions are exactly the same for all files as the ones in the projects that do open in Xcode. I changed permissions for everyone to ReadWrite just in case, to no avail. I feel I've tried everything obvious and can't seem to find anybody else with the same problem.
Anyone got any ideas about a fix or workaround? Typically it was one of the only projects that was actually completed so its very frustrating!
Thanks.
I ran into the same problem and found that clicking on the project in xcode and then switching the view to standard editor view will let you change all of the project settings. After editing the summary, info, and build settings areas it started working
Click to project-> Build Settings -> Compiler for C/C++/Objective-C -> Default Compiler. Hope it useful :D
