So here's the deal:
I am building an app that accesses the internal addressbook on the iPhone. Everything was working fine (and is working fine on the simulator still), but now on the device I get a ThreadBreak and lldb opens up with no error message in the console on this line:
tempPerson.firstname = ABRecordCopyValue(person, kABPersonFirstNameProperty)?.takeRetainedValue() as String? ?? ""
Again, this is still working on the simulator mind you and used to work just fine.
There is some multithread action going on because I am loading the addressbook into memory in the background using GCD above:
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), {
My addressbook was loaded properly. I have deleted the app from my test device (iPhone 6), cleaned the project (figuring it could be a bad link between some Obj-C bridge file that didn't like the ABAddressBook datatype, and even hopped on one foot while holding the phone Northward for good luck. Nothing worked.
I just can't figure out why it would work on all the Simulators and not on the phone. I do, however, notice that the app is not asking permission to access the contacts when it firsts opens after deleting (though the Authorization check is called and is granting authorization):
case .Authorized:
return self.createAddressBook()
I'm at a loss at even what to show you all since it's not returning much of anything, but here is a breakdown of the Thread Error (NOTE: Sometimes it happens on different threads...)

On the breakpoint, the two variables given in the debugger are
The addressbookref
adbk = (AnyObject?) (instance_type = Builtin.RawPointer = 0x... EvaluatingTo: Some
and the ViewController called "Self"
self(SomeApp.ViewController)
containing all the variables my app uses elsewhere.
Sorry for being so verbose, but I really don't know what of this is relevant and what isn't.. Thanks for your help in advance!
Update: I turned off multithreading/ dispatching and it didn't work. So it must be something to do with that tempPerson.firstname bit.
Update 2: It does go around the loop twice and get two contacts before failing. I think it is hitting a nil value that isn't quite nil for some of the contacts and then crashing.. I do have the following check for it though and it is passing through:
if ABRecordCopyValue(person, kABPersonFirstNameProperty).takeRetainedValue() as AnyObject? != nil{
&
if ABRecordCopyValue(person, kABPersonLastNameProperty).takeRetainedValue() as AnyObject? != nil{
respectively.
Update 3: Okay. So Now it seems whenever there is a blank field for first or last name it crashes (on the simulator now too). Which really sucks because I thought I put in a good check to make sure I am not accessing nil valued properties. Whats even more annoying is that I haven't changed this code and it was working fine until I removed some derived data and changed the test file to avoid a linker error. Anything that could happen in the build process that is mucking up my code?
