I'm brand new to iOS development (and MacOS in general). While waiting for a mac to arrive I've set up a Virtual Machine running Mountain Lion to get started with developing.
When trying to run a simple Hello World application, the simulator crashes with "The simulated application quit" error message.
In the User Diagnostic Reports there is the following crash report:

Any help with debugging this would be great as I'm not sure where to start with fixing this.
Can you run the simulator stand-alone, not through XCode?
If so, can you run any of the built-in applications?
I'm not sure what may be causing this but it could well be some low-level interaction between the simulator and the VM. You should also bring up Console and see what is logged to the system when you try to run from XCode.
"Reset Content and Settings" resolved this issue, however I think it was combined with a step I made earlier in my attempts at debugging, as at the start I also tried resetting the contents and it didn't work...

I have a macOS app with a GUI which runs 24/7 and as of last week worked flawlessly. Three days ago I updated my Mac mini late 2012 to macOS Catalina. I started my app again and it worked. The next morning I encountered an EXC_BAD_ACCESS error which crashed the app (see below for more information). Restarted the app, error reappeared next morning and this morning, too.
Background: I don't expect hardware to have any influence since it was never any issue but still: I have a display attached, which through a connected power plug gets turned off at night and turned on again in the morning.
Here's the error:
CVDisplayLink (989): EXC_BAD_ACCESS (code=1, address=0x40)
In the log before the crash this message appears roughly 50 times, not sure if it has anything to do with the crash itself:
CVCGDisplayLink::setCurrentDisplay didn't find a valid display - falling back to 60Hz
and
Could not start the display link: -6661
I attached a screenshot with the threads in question and the last commands. I don't find any connection to my code... The app crashes always at the exact same location (I think).
Any help is highly appreciated! My next step is to leave the display on during the night and see if the error reappears. Even if no, that's no solution as I want the display to sleep during the night and other times...
Here's a crash report:

and this:
I haven’t received any answer from Apple (it’s been months!) so I went ahead and downgraded (which I did not want to do) to Mojave. I haven’t had a single hic up or problem since. I am bewildered.
My application crashes when I try to scroll the tableview very fast or reload the data from remote. Everything seems to be working fine, when I let the remote fetch happen first and then scroll the tableview. I have no idea what the crash log below means. It just works fine sometimes and crashes sometime.

I would be really happy if anybody could explain me what this crash log could relate to and how I could solve it. Many many thanks to all those who are willing to help others.
Seems to me that it's dangling pointer, and you're sending message to it.
As MikeD said, use breakpoint on exception if it can help. But it's not 100% reliable since you get a SIGSEGV and not a SIGABRT. And the exception throw is not really the cause of the crash, just a border effect.
Edit
Ok: In your log crash, it says that libsystem_kernel.dylib has crashed in a kevent call. That won't help you since this is private and opaque, and you can be 100% sure this lib do its job well. This can appears because you have used (unintentionally) a space memory where you should not write into. Like with a dangling pointer. Let's say you have allocated memory to 0x2000 and you have a pointer pointing to this memory, if you freed the memory but still using this pointer to this address, if someone else (like libsystem_kernel) use it, and you change some data in the same time (because of your dangling pointer). Then the other side will use data corrupted, and some random behavior will occur. That's why if you analyze literally your crash log, you'll do wrong statement. Because kevent from libSystem is stable.
By the way you have thread 1 who crashed, but look into thread 0, it was trying to raise an exception too, but it didn't get time to do it. This can occur because of data corrupted too.
That's why I recommend you to make another crash, and compare it to this one. If the crash log are the same, then i was totally wrong. If the crash log are different, this is a dangling pointer.
My XCode crashes and crashes and crashes and i can't open my project here is the error that i receive

I tried removing xcuserdata folder from .xcodeproj file that didn't worked
I tried removing the project from repository in XCode -> Organizer
I tried removing the derived project data that
I really don't know what the problem is, we are using a SVN server on the network so we can sync the sources of the projects.
There is a good chance that is fixed in Xcode 4.5.1:
Source Control
Issues interacting with working copies known by the Xcode app. 12364258, 12389205, 12389198
The release notes are available on the Apple Developer Download site (here); they don't appear to be updated on the main Apple Developer website.
Details: Attempted to add repository (IDESourceControlRepository) Name:192.168.1, Type:Subversion, Location:svn://192.168.1.20 when (IDESourceControlRepository) Name:192.168.1, Type:Subversion, Location:svn://192.168.1.20 already existed.
I would remove all your repositories from Xcode and add them again.
I am running Xcode 4.5.1 and just started having this problem today. The app was running in the simulator and then the simulator started acting funny so I decided to stop everything and close Xcode. I had to blast it. When I tried to relaunch I got this error and cannot launch anymore. Clearly something got messed up.
I am having a big problem figuring out where my app crash is being caused, and I'm not sure how to interpret the crash report.
The crash clearly occurs in Thread 0, but at what step might it actually be crashing in? I certainly am not manipulating CALayers in my code at all. In anyone experience, does this happen for any particular reason?

UIViews are implemented with CALayers, so if you are using UIKit, you are using layers. My guess is that an already released object is receiving messages. Maybe you released an object more times than you should. Try recompiling with NSZombieEnabled.
3 UIKit 0x331b0f72 -[UIView(CALayerDelegate) drawLayer:inContext:] + 270
By any chance, did you release an objectA which is a delegate to objectB without removing the delegate assignment first, i.e. objectB.delegate = nil; [objectA release];?
My app uses background location for GPS updates. I've registered it for background location updates, and while it's running in background, it always crashes like this.
Since I haven't written most of this code, I really have no idea what happened.
I have checked the memory allocations and there doesn't seem to be much of a problem there. Here's a crash report:

Unknown thread crashed with unknown flavor: 5, state_count: 1
I think you need to check some objects which are released by other threads, but they are accessed by main thread. I encountered something like this, and it was because I accessed some objects which had been released.
I had precisely the same crash logs being generated. I have a main thread, which uses an NSOperationQueue to spawn a data download thread, which then uses performSelectorOnMainThread when finished.
In my didupdatelocation method, I was cycling through an array, launching a local notification in some cases. It seemed to fail on the SECOND instance of a local notification (for the same array item), but I cannot be sure. I did try symbolicating the logs, but there is some missing file error with 4.2.1, so I'd copied in symbols from 4.2, and couldn't get atos to work (but that was probably my fault).
Last night I made the following changes, and all seems to be resolved:
1) changed all self.locationManager notation to just locationManager
2) removed everything from the dealloc method in the appdelegate (aside from super)
