I have recently downloaded Xcode update 4.5.2 and it seems to performing slow. I have tried other applications and everything is running fine. I'm currently developing an app and it's been performing so slowly, that I can't edit an UIlabel box.
Just in case: remove the contents in the "~/Library/Developer/Xcode/DerivedData" - Folder and see if it still stalls. I had a sluggish Xcode once and that helped.

Whenever I try and add any SpriteKit elements to my project, Xcode crashes. The files are created but not added to the project and if adding them manually, it still crashes when trying to open them. After some searching it looks as though previous versions have suffered with the same issue. I had the same issue with 8 beta 6 too.
Is there anything I can do to help with the issue? I can't find anything on the most up to date version so I'm guessing it's either something I'm doing or a problem with my setup.
I've the same issue when I try to maintain 2 Xcode versions in the same system, it is possible but you should install them into separate directories, for example Xcode_731 and Xcode_8 (my actual version is 8A218a GM, I haven't any crash).
This should be unuseful without crashes, but try also to free some memory (quit also simulator app after your crash), in your terminal:
sudo purge
After updating OSX and Xcode to latest versions (10.8.4 | 4.6.3) projects with cocos2d 2.0 works fine but...
When I tryed update cocos2d to 2.1 new projects want not build. Xcode just closes with error.
Full error description here: https://docs.google.com/document/d/1JhqD3CW2JRKEXZquQIYN4grVG3siDL4jqcFByhGDgGM
After this error projects with c2d 2.0 that works before starts crashes too.
Back cocos to v2.0 does not give any profit.
Problem resolved.
I use RealVNC server on my home mac and client on win7 PC at work.
Xcode crashes when I try build/run using shortcuts (command+R, command+B, sometimes command+z)
When I do this using menu, it works fine.
Weird, why this starts after cocos2d 2.1 installed...
So, I think, problem with OSX 10.8.4 + RealVNC.
Weird weird weird...
Directly Mac works fine.
P.S. I hope this will be helpful for another internet pilgrims.
i recently received my Macbook and wanted to start developing iOS apps with it.
I Created a default Master-Detail App using the Templates in Xamarin.Studio and everything worked.
Now today i wanted to actually do something in the app, but didn't change a single line of code, still the app doesn't show up anymore in the simulator as long as i want it to use the 6.1 sdk for ios. if i use any other (6.0 etc) it works fine.
I already tried clearing my Cache in /Users/MYNAME/Library/Xamarin/ but this didn't change anything.
What would you suggest me to do now? can i simply reinstall the 6.1 sdk?if so, how would i do this?
Thanks for your help
I had a similar problem where the environment hang when I was trying to debug in the simulator (just showing the spinning ball). I found out that it only occured if I had my phone connected to the computer. Perhaps not valid in your case, but it might be a lead in your problem solving.
I'm using the latest version of everything. :)
From within Xamarin Studio (or MonoDevelop):
Project -> Your.Application.Name Options
Build -> iOS Build (iPhone Build in MonoDevelop)
SDK version: -> 6.1 (it's probably still on 6.0)
This fixed it for me. Also, it wouldn't hurt to make sure the target build in info.plist is set to 6.1.
Delete this folder:
/Users/[username]/Library/Application Support/iPhone Simulator/6.1
And if your Library folder is hidden:
sudo chflags nohidden ~/Library/
I have experienced this problem several times again and my previous answer doesn't solve it. Ya know what does? Rebooting the computer. Works every time. shrug
You need to fill the Application name, Identifier, Version # in the project setting.
I had the same problem and got it solved that way.
Hi I just upgraded to Mountain Lion. I created an empty Single View Application and run it. The first time it runs fine but the next runs will give me the "There was an internal API error" pop-up warning TWICE. It's the same with my other projects. They run okay once but gets this error the next runs. There was no warning or any specific warning message of any kind.
Any idea how to solve this?
Would really appreciate your help.
I have it working on iOS6 Beta 4!! This is what I did but other variations may also work:-
Install XCode 4.5 Developer Preview 4
Delete your app from the device
Run your app from Dev Preview 4
Delete your app again (not sure if you have to do this)
Return to XCode 4.4.1
Run your app, stop running, run again!!!
Of course you could continue developing in 4.5, but I prefer to wait.
Installing 4.5 Beta 4 installs updated device support. Once this is done once (possibly on any device) it should work fine. If you use the same device on a different machine you will have to again run it once from 4.5 Beta 4 before using your preferred version of Xcode (You do not need to delete the app from your device this time).
Edit: I am pretty sure that if you make a change to your core data you will need to run from 4.5 for the first time also.
Don't know if this helps, but I've deleted all files in ${HOME}/Library/Developer/Xcode/iOS DeviceSupport and it worked as a charm (Xcode 4.4.1, OSX 10.7)
I had this problem when I upgraded my device to Preview4 but had my MBP still running Xcode Preview3. Updating to Xcode Preview4 made the problem go away for me, no restarts necessary.
Deleting the app manually from the device/simulator will allow you to build and run successfully. A long term solution is to not use a Beta Xcode :)
Sounds crazy but you can also not use the Beta version of XCode 4.
However, you must keep it in your left hand to authorize your iPhone to compile with the non Beta version (don't ask me why, it works).
If you run your app with XCode 4.5 preview & IOS6 Beta 4, the second time you run your app on the device, you'll get the internal API error.
In theory, you cannot use XCode 4.4 to compile on your iOS6 Beta 4 iPhone.
But...
It seems that, if you launch XCode 4.5 Preview, connect your iPhone (so it is recognized), run the application on it (even if you get the error), quit XCode 4.5, launch XCode 4.4 and .. tadaaaa... your iPhone is now recognized as an authorized device to compile on...
And of course, XCode 4.4 doesn't generate the api error...
I have Xcode 5.0.2 and iPhone with iOS 7.0.6.
Every time when I launched my project on iPhone, I saw "There was an internal API error". And it was launched on simulator without any problems.
I did all the stuff that usually helps (like remove an app, clean, restart Xcode, restart a mac, etc.).
This problem went away only after I restored the iPhone. Sad but true.
I don't know so far, why it appeared.
I've got 2 applications using Core Data with a sqlite persistent store. I've got a data loader routine that I run to populate the CoreData DB from csv files. During development, when my data changes I run the routine from the simulator to generate new databases and copy the new one into the project.
This has been working quite well for XCode 3.2.3 and iOS 4.0. It even works in the XCode 4 Preview 2 and 3. I just installed the final version of XCode 3.2.4 and iOS 4.1. Now my db loader fails. It gives me no message, no warning, no nothing. It just dumps out to the spring board and XCode gives me the "Debugging Terminated" message. It will fail at different times during the load so I'm pretty sure it's not a data issue. I'm not doing any threading. I assume the issue has to do with either Core Data or sqlite, since that's when the crash occurs, but with no info reported I can't tell for sure.
I uninstalled everything. Xcode 3.2.4, Xcode 4 preview (assuming it was an issue caused by XCode 4) and reinstalled XCode 3.2.3/iOS 4.0. Things returned to normal. After getting some work done I attempted to upgrade to 3.2.4/iOS 4.1 again. I uninstalled 3.2.3/iOS 4.0, rebooted. Installed 3.2.4/iOS 4.1, rebooted and tried again. No luck. Same hard crash. Same lack of messaging as to the cause.
I have determined that this only happens with the Simulator with XCode 3.2.4, the device is fine as is XCode 4 and 3.2.3. I've tried playing with the target OS selection (3.0,3.1,4.0,4.1). I've tired adjusting the Compiler from GCC 4.0, GCC 4.2,LLVM GCC 4.2, LLVM 1.5. I've tried setting the Base SDK to iOS Simulator 4.1. Interestingly enough it will work in the iPad simulator when using the 3.2 SDK. So I've at least go that as a work around.
I guess there is one of 3 issues:
An issue with my code that has been uncovered by 3.2.4.
Bug in 3.2.4.
A configuration issue that I've missed.
If anybody has any troubleshooting ideas or answers I'd love to hear them. I've been doing iOS full time since V 2.1 and I am seriously stumped.
Thanks in advance,
I figured out my issue. It looks like the CoreData/Sqlite connection was a total red herring. Following a tip I read on SO, I used OSX's Console application and got a critical message "Failed to launch in time" that was not being displayed in XCode's debugger console.
It looks like the process was being killed due to what is essentially a timeout error. The iPhone will kill an application that takes too long to complete "didFinishLaunching." That's where I was kicking the data load routine off from. The new version of XCode must have adjusted it's timeout values.
So my takeaway is give OSX's console a shot if XCode isn't telling you everything and watch out for those red herrings.
When I upgraded I ran into troubles in the simulator when saving the managedObjectContext. I finally deleted my sqlite CoreData store file and have not run into similar problems. Try deleting your data file (well save a copy of it before deleting to see what is different).
