Xcode error on startup, possibly due to too many open projects

Question

I just got a new Mac and downloaded Xcode to keep things fresh. When I first opened Xcode, I accidentally told him to open my src / folder instead of / src / myLatestProject, so my Xcode guess went and tried to open every project in my src / (hundreds) directory. He swam for several minutes, and then crashed. The problem now is that Xcode seems to remember that I want a lot of projects to open when the application starts or try to parse hundreds of git repositories, and I'm stuck in a clean open / beachball / crash. How can I reset the Xcode prefix so that it does not try to be so useful and open every bit of the source code on my computer?

EDIT: I confirmed that this is only a failure for my account. If I create a test user and open Xcode, everything will be fine.

Answer 1

Not sure which one was fixed, but I ran the following in the terminal and now it works again:

 cd ~/Library sudo rm -rf './Preferences/com.apple.dt.Xcode.plist' './Autosave Information/com.apple.dt.Xcode.plist' './Autosave Information/Unsaved Xcode Document.xcworkspace' './Caches/com.apple.dt.Xcode' 

ATTENTION: Please note that this may remove other settings, such as key bindings, so be careful if you have many xcode environment settings.

Answer 2

Open finder and go to the following path and delete the folders made by them, these are folders created each time you open any project in xcode temporarily:

 /Users/MyMac/Library/Developer/Xcode/DerivedData/ 

Answer 3

My Mac Xcode6 / Yosemite does not have an Autosave Information folder, so I deleted the ~/Library/Saved Application State/com.apple.dt.Xcode.savedState folder and stopped it.

Answer 4

If you have an open swift file in a new window (for example, when you double-click on a .swift file in xCode and open it in a new window) when opening xCode this can be a problem. I think I opened this window when closing xCode, and then when opening xCode, this window opens again and for some reason resets xCode. Try closing this open window quickly before it works. Strange, but it worked for me.

Answer 5

The script for the Xcode crash was a bit different on my side. Indeed, I had the same call error:

 Application Specific Information: ProductBuildVersion: 5A3005 ASSERTION FAILURE in /SourceCache/IDEXcode3ProjectSupport/IDEXcode3ProjectSupport-3575/Xcode3Sources/XcodeIDE/Frameworks/DevToolsBase/pbxcore/Xcode3Model/Xcode3OCUnitTestableDataSource.m:191 Details: ([_indexableIdsToTestableTokens objectForKey:indexableIdentifier]) should be nil, but it is <Xcode3OCUnitTestableDataSourceToken: 0x7fe73b531ae0> Object: <Xcode3OCUnitTestableDataSource: 0x7fe7359c79f0> Method: -setTestableToken:indexableIdentifier: Thread: <NSThread: 0x7fe732415570>{name = (null), num = 1} Hints: None 

But I had to duplicate an existing project (.xcodeproj file) in order to have an application in my workspace depending on other projects (Target Dependencies in Build Phases) in my workspace (used as a debugging application), and the application does not depend on anything or related only to the final result of the assembly of the corresponding project target (in my case, the framework inside Link Binary With Libraries in Build Phases). The problem was that every time I imported a duplicate project into my workspace, it crashed Xcode ... Since the trace of the error stack was talking about test things, I just looked at the project.pbxproj file and deleted all occurrences of the test line in this file (well, I pay attention to the section so as not to damage my file).

Something is wrong with the duplicated xctest target inside prject. As soon as I tried to import it again in my workspace, it worked fine.

Hope this helps

Answer 6

I completely deleted the Library / Developer folder: Close Xcode

 rm -r /Library/Developer 

And say yes to each file

Answer 7

No solution worked for me if you have a workspace. But I found out about it.

• delete the workspace file if you have one. install pod again using "pod install" in the terminal (you need to move it to the project folder).

• reopen the workspace .. and he will solve this problem.
