I was propted by apple to upgrade my debugger settings yesterday, In doing so I have some how broken xcode.
When ever I now try to load an application (dosn't matter what version of the simulator I am using) Xcode and my simulator both freeze up. then the rainbow loader just sits their constantly turning over.
Is there any way to fix this? I'm really stuck and don't know what to do as it dose not seem like a very common problem from all the research I have done to fix this.
I am running the latest version of xcode 4.3.2 (4E2002) and using 5.1 simulator.. and have tried 4.2 simulator to the same effect.
any help in getting my xcode back up and running would be massively appreciated.
Okay so I figured out what the problem is but not a real solution...
Basically the error started happening when I was prompted by xcode to update my debugger to the LLDB version. this is what cause my simulator to keep crashing xcode.. or vice versa honastly I still dont know why this is happening but yea...
so.. what I did to get this simulator working again was go to Product>edit scheme> debugger then changed from LLDB back to GDB.. this solved my issue for now... however I need to figure out why LLDB is not working and what I should do leading into the future. hope this helps someone else.
I have facing this problem too but I got a solution either you said its temporary ... some time ios 5.1 simulator hangs when I shifted to the ios 4.1 sdk its a common practice for the developer to check it I have simply first close the simulator and again start it and then reset all the content in the preference area that its resolved my issue .. check it might be you also got resolve for apply this trick or technique.
Thanks
In my case, was too many old breakpoints tracks (788), even to deleted files, I just clean it and now it runs perfect, I hope it helps.

I am confused, whenever I have an error in my Swift code, the building of the app in the simulator fails.
Today, even though I am pretty sure the code is correct (and it works), I see a few errors in my code, and even so, the app-building is successful in the simulator.
Anyone has run into this before? How can I fix it?
Thanks

This isn't a solution, but have you tried restarting Xcode?
My IPhone app is suddenly giving a SIGABRT error message when I attempt to run it on my iPhone, before even the first line of the application delegate is reached. It runs fine in the simulator, and even restoring previously working snapshots give the same error when I attempt to load the application on the device.
I fiddled with the Product Name build setting and the data model prior to the problem occurring, but as mentioned, old snapshots that ran fine now won't load, suggesting that the problem isn't in the code.
I have tried restarting xCode, the computer, the iPhone and deleting the app but the problem is still occurring.
I am sure that the problem lies with the device
Any ideas what the problem might be or how I can fix it?
Taking on Till's suggestions I reinstalled iOS (well, actually I updated it to 5.1) and everything is working again. Thanks for the advice. I've no idea what went wrong, but at least its working again now!
I've imported an iPhone app that I have developed for iOS and am now maintaining it. I've came across a couple of bugs when trying to add to the iPhone's calendar, which I'm happy to try and sort out myself with a bit of debugging.
One problem is that when I go to run the application on the iPhone simulator, it seems to run an older version of the app than the one I am running. I've removed and added another button since then and the old button is still showing when I run it in the simulator. However, when I compile and run this on a device, it loads the correct version and displays the correct version number in the 'about' view.
But... my main problem is that it doesn't seem to debug on the device properly. The app actually works fine except for the calendar problems, but if I put a few breakpoints in so I can see exactly where this is going wrong, it just doesn't seem to step through! The app pauses, and Xcode says the app has paused! I can press step over and continue execution etc and it appears to work, but I can't see it stepping over the code, nor can I hover over variables to see their values.
I've tried reinstalling Xcode multiple times (I did have a problem installing an older version, so I had to wait until the next version was available before Xcode would install).
The stress is: Today is my last day at work, and I'd really like to get this app ready for iOS 5 before I leave.
Has anyone seen these symptoms before? Is there a debug setting that I've missed? Or is it a corrupted installation?
I wish I could help people a bit with more information, but I don't even know where to start looking here. Any code I can post? any settings? (not too familiar with this, I'm a .NET guy usually).
Thanks!
Sorry you're going through a tough moment there Connell; as you said you're not too familiar with all this, I'm laying down a few steps which might help you out. Some are pretty basic, yes, but I've resolved to these steps myself several times when I've encountered similar scenarios;
If you're testing on the simulator, do a 'Reset Content and Settings' from the 'iOS Simulator' main menu. This will remove all old data and settings and give you a clean start.
Do a 'Clean All Targets' from the Build menu. Then go to your physical project folder and delete the Build folder from it altogether before starting to build again.
Restart both XCode and the Simulator (and your Mac too if possible)
Make sure the mode is set to Debug and not Release or Distribution
Even on the device, remove the old app before putting the new one in, and restart it for good measure.
Delete all Provisioning Profiles from the device and install just the one you need.
On the code;
I've noted that the app appears to 'pause' like this a couple of times when I had accidentally created an infinite loop in the code. Double check to see whether there's something which may cause this.
Unless you haven't already done so, throw an NSLog or two in there to see if its really not being executed beyond the breakpoint.
I've had the exact same problem with a project that I started on xcode 3 and then switched to xcode 4. What fixed it for me was changing the compiler in the project settings.
The default compiler up to xcode 3 was gcc, while the default compiler on xcode 4 is LLVM gcc.
Now, I don't know exactly what's the issue that gdb could have with LLVM gcc, but switching the compiler back to gcc in my project settings and doing a clean build fixed my debugging issues.
Might be worth a try.
Have you checked which debugger is being used GDB or LLDB? Select Edit Scheme from the Product menu, and see what the Debugger setting is under the Debug scheme. You could try switching between GDB, LLDB, and None and running in between.
I have sample application it works fine. When i set breakpoint in my project it didn't step over from breakpoint, the application hangs with that break point its really hard to find what the problem is. With out break points its work fine.
I want to test some variables with breakpoints in simulator 4.0 debug can anyone help me?
Thanks in advance....
I had this issue until I upgraded to the latest XCode 4.5. Its seems to have solved the XCode - Not Responding issues and Crash. Hope this will help.
When I start my iPhone application it boots up fine, shows the first settings screen and all after I have given input and pressed save, the debug window says
Debugging Terminated
without any hint to why in the crash logs.
First I thought it was my programming, but then I went ahead and tested the app on multiple 'real' iPhones and it never crashed.
Why does the simulator keeps crashing?
A common cause of crashes on the simulator but not the device and vice versa is using precompiled libraries that were compiled on the other hardware. Check if you've got something compile for ARM that is trying to run on the Intel.
In XCode try Build > Clean All Targets
Have you tried resetting the simulator? iPhone Simulator -> Reset Content and Settings
Then do a clean build of your project.
Annoying :)
Put NSLog statements around where you think that it's crashing and look at the output. That shoud give you more of an idea where the crash is occurring.
If that doesn't help, post the lines causing the crash in the question and see if anyone can help then.

This tends to happen when you declare a variable and then use it without actually creating it. I would check variables you are using to make sure you are actually creating them before using (i.e. with alloc or the convenience methods).
