It's something that I didn't know till an hour ago or so, but if your application tries to access Contacts (previously, Address Book) data through the ABAddressBook Class, the user will be prompted for confirmation just as you will be prompted for confirmation when an iOS application tries to access Contacts data. Then the Security & Privacy Preferences Pane will be updated, and you will see your application listed under the Privacy list.
So if you try to access Contacts data with the application blocked, you will get an error with Xcode stating like "Address book access is denied for executable at path..." You can check the privacy status with ABAddressBookGetAuthorizationStatus() in iOS. How do you find out if your application has privacy permission in OS X?
Additionally, if you have the answer, I wonder where Mac OS stores the list of applications under the Privacy tab? I've checked User's Preferences folder. But I don't see any file with it.
Thank you for your help.

The following is an error output shown when the application attempts to access ABAddressBook with ABAddressBook *addressBook = [ABAddressBook sharedAddressBook];:

If the user grants access, your application can access ABAddressBook as usual. If the user denies access, the addressBook and sharedAddressBook methods of ABAddressBook return nil.
I don't think there is a way to avoid that exception (which doesn't match what the docs say should happen). So, you can add that section of code where you try to get the sharedAddressBook into a try catch block and avoid the app dying if the exception is thrown.

The code is as follows (I isolated it through print statements, the error happens in these lines):
let request = NSFetchRequest<Group>(entityName: "Group")
request.sortDescriptors = [NSSortDescriptor(key: "id", ascending: false)]
let groups = try! context.fetch(request)
Notes (edited):
SQLite backing store
XCode 12.3
I have checked the basics, there exists a Group entity with an id field.
Even if there is a simple solution, would be also very grateful for a bug-fixing strategy here. Is there some way I can read through documentation to figure this out myself?

CoreSimulator 732.18.6 - Device: iPhone 11 (93AB6812-3722-4022-B989-2E1423E6E6D0) - Runtime: iOS 14.3 (18C61) - DeviceType: iPhone 11
Sorting on UUID fields is normally not supported by Core Data. To get it working, change the key path to a string type, like this:
[NSSortDescriptor(key: "id.description", ascending: false)]
Key path id.uuidString would theoretically be better, but this still gives the same crash as described in the original question (at least in macOS 11).
The default core data code is throwing an error for some reason. This just started happening after I attempted to migrate to a new version of the data model, so I'm sure I did something to screw this up. Here's the relevant code:
enter colazy var managedObjectModel: NSManagedObjectModel = {
// The managed object model for the application. This property is not optional. It is a fatal error for the application not to be able to find and load its model.
let modelURL = Bundle.main.url(forResource: "Band_Manager_2_0", withExtension: "momd")!
return NSManagedObjectModel(contentsOf: modelURL)!
}()
The line throwing the error is this one:
enter let modelURL = Bundle.main.url(forResource: "Band_Manager_2_0", withExtension: "momd")!code here
And here is the error:

I'm hoping someone will have some insight as to how to fix this. I'm relatively new to core data and it's brought my coding to a complete standstill as, of course, the app crashes immediately after launch.
Thanks!
UPDATE: I should clarify, that I understand the technical reason why this is happening (not finding a resource needed) but I have no idea how to fix this. The resource which it can't seem to find is something that was automatically generated at some point in the past. I can't seem to figure out how to get XCODE to regenerate the needed file, or even why it went missing in the first place.
Ok. So I figured this one out...
About a week ago, I renamed the core data file to from "Band Manager_2_0" to "bmData", and for the past week everything has been working fine. However, today, while I was migrating data, it finally "broke" the connection.
I have no idea why the connection didn't break immediately upon renaming the file, which would have clued me into the problem. It must have cashed the location in a way that I disrupted today.
What is particularly confusing is that the code is looked for an extension of "momd", however the actual file has an extension of .xcdatamodeld... obviously something behind the scenes in XCODE 8.
Regardless, this problem has been solved.
I am using the recent facebook sdk and parse sdk for ios. When i try to run my app on the simulator i get the following error:

I managed to fix this error doing the following:
First I deployed the official version of Parse Server (instead of Rob's version). Open this link and click 'Deploy to Heroku', follow the steps. https://github.com/ParsePlatform/parse-server-example
After that I downloaded the Parse Frameworks (including Facebook framework) from the link below and replaced all current frameworks in my project with these frameworks downloaded. https://parse.com/downloads/ios/parse-library/latest
Other than that just follow the class steps (adding code to AppDelegate, Info.pslist e etc.
Any problems, let me know.
I had my iOS App up to 98% completed on Xcode 4.6 and iOS 6.1 and it's working OK.
But then problems begin when I try to update my Xcode to version 5 and the SDK to iOS 7.
When I try to run the app on Xcode 5 but with iOS 6.1 it continues working ok, but when I tried to run on SDK 7 I have these issues:

libc++abi.dylib: terminating with uncaught exception of type NSException
Theres simply not enough information to correctly debug this item.
I can recommend however that you add a Breakpoint for all Exceptions
Here is an example of adding an All Exception breakpoint in XCode 4. The process is the same in XCode 5
http://www.alauda.ro/2013/02/03/xcode-4-exception-breakpoints/
Aside from that you may try working with NSSetUncaughtExceptionHandler
http://www.cocoawithlove.com/2010/05/handling-unhandled-exceptions-and.html
This will allow you to trap the error and output the results but bear in mind that this is something you should only do during debug.
Wrapping it in an "#if DEBUG" is a good idea.
I hope this helps you out. These kind of bugs are a pain to fix.
NOTE
You may check if the key value set you are using didn't change between SDK's
Are you by chance sending the message valueForUndefinedKey: to the class MKUserLocation?
Here's what the class reference says about getting user location:
"The MKUserLocation class defines a specific type of annotation that identifies the user’s current location. You do not create instances of this class directly. Instead, you retrieve an existing MKUserLocation object from the userLocation property of the map view displayed in your application."
https://developer.apple.com/library/ios/documentation/MapKit/Reference/MKUserLocation_Class/Reference/Reference.html
So, when developing, I get a crash when running the app in iPhone simulator. Say something like this in the console...

terminate called after throwing an instance of 'NSException'
(Details of crash don't matter, just an illustration.)
Now, it used to be the case that when I get such a crash, I can run Xcode debugger and get the call trace conveniently loaded there, so that the debugger loads the call stack and I can interactively navigate in the methods that were called just at the time.
But ever since installing Xcode 3.2.3 and/or switching computers, this doesn't work. I load debugger at this point where my app is halted, but it comes up empty, no call stack.
I'm sure there is an Xcode setting I have missed somewhere, but didn't find anything on my own quickly glancing through settings. What do I need to do to get the call stack loaded in debugger at this point?
Sometimes, for some reason the XCode debugger stops in a place where it simply cannot pick up debug values. I've seen it when trying to stop in callbacks for animations. There's not a setting you can really chose to fix this (though you should check you are running in Debugn and not Release, and that debugging symbol generation is still checked in project settings).
You might try using the LLVM debugger in XCode 4.
However, to solve your particular problem - it seems pretty clear you are trying to insert an object into an array in +didReceiveEvents:WithVerb:ForDomain: in BucketsTable, where you are inserting some point too far after the last element in the array. You might try an NSLog around any array insert there with index and object values.
