My app does not crash on iOS 8.
But after updating it to 10 version on my phone, my app crashes when I try to use specific functions in the app.
But on simulator, it works well.
Whenever I installed the app on my phone, Thread # issues happened. And the number on # part always changes like below and I don't know why.
libsystem_kernel.dylib`__abort_with_payload:

what does the below error mean?

And some comments mentioned that I can solve this issues if I deleted "search path" on info.plist. So I tried to delete "Search Path" on info following them but it didn't work at all.
This issue is solved.
The reason is microphone provisioning on info.plist.
Therefore, I added "privacy-microphone" menu on it.
And it's solved.

I found that I needed to input 6 integers, and that the integers consist of 1 to 6.
And I found the node1 ~ node5. But, this phase needs 6 nodes.
So I looked for more, but instead of node 6, I found'host_table'.

What is the 'host_table'? I thought 'host_table' was node6. But it wasn't.
This is the code of this phase.

When I saw other people's solutions, They did x/3x $esi to find out the node1.
But, when I did it, I got an error.
what should I do?
I am trying to write my first Swift application, and its running great!… in the simulator. The application is generating tones via AVFoundation, and it works well when I start playing the tones on the iPhone, but as soon as i try to stop the AVAudioPlayerNode, then 5 out of 10 times my iPhone application freezes up. Everything is working perfectly in the simulator.
Here are the stopping code:
#IBAction func togglePlay(_ sender: UIButton) {
if tone.isPlaying {
engine.mainMixerNode.volume = 0.0
tone.stop() // This is where is freezes up and tone is a AVAudioPlayerNode
engine.reset() // engine is a AVAudioEngine
sender.setImage(UIImage(named:"icons8-play-100")!, for: UIControl.State())
} else {
tone.preparePlaying()
tone.play()
engine.mainMixerNode.volume = 1.0
sender.setImage(UIImage(named:"icons8-stop-filled-100")!, for: UIControl.State())
}
If i pause the code when it freeze and look at the stack trace, then it looks like it's waiting for some sort of Mutex be be released. But I'm not experienced enough to know how to investigate further on what i'm doing wrong
Here are the stack trace:

What would be next step in debugging?
Pay attention to threading in your audio engine setup.
Had the same issue when saved audio frames from the injected equalizer unit:
equalizer.installTap(onBus: 0, ... ) { buffer, _ in
...
status = ExtAudioFileWrite(file, numberOfFrames, audioBufferList)
...
}
Mutex interlock was fixed by forwarding ExtAudioFileWrite call to the main thread

I set an exception breakpoint that led me to this bit of code:
if let defaultFormula = dataManager.fetchDefaultFormula(moc) {
self.formula = defaultFormula.first! <<< Unexpectedly found nil...
}
and here is the function it's calling:
func fetchDefaultFormula(_ moc: NSManagedObjectContext) -> [Formula]? {
let defaultFormulaID = UserDefaults.formula()
let fetchRequest = NSFetchRequest<NSFetchRequestResult>(entityName: "Formula")
let filterPredicate = NSPredicate(format: "uuid = [c] %#", defaultFormulaID)
fetchRequest.predicate = filterPredicate
do {
return try moc.fetch(fetchRequest) as? [Formula]
} catch {
fatalError("There was an error fetching the lifts")
}
return nil
}
The fetch request is returning 0 values so it's clear why I get the exception when I force unwrap it. However, the object property 'formula' must have a value. The first thing the app does is check to see if the default data (like the available formulas) exists in the persistent store and if it doesn't, it adds it. I've reset the Simulator and it dutifully adds them but it seems that this isn't happening on the iPhone. If there's a way for me to determine whether or not the records are being added to the store when running it on the iPhone, please enlighten me.
I've found a few SO threads in which others have experienced this cryptic error (the big, ugly one, not the unexpected nil) and I've tried all of the remedies suggested:
cleaned the project unplugged the iPhone, plugged it back in
restarted all devices
changed the Team to None and back to me
turned off Automatically manage signing and turned it back on
downloaded my current certificates
turned some flags from No to Yes in Build Settings
etc
I don't know where to go from here having exhausted all of the suggestions I've been able to find.
Any suggestions are greatly appreciated.
Well, I guess there was one thing I didn't try - uninstalling the app from my phone first, then build and run it on the phone.
So I don't really know what the root cause was, but at least this resolved the problem.
I am new to visualGDB. Recently I new a stm32 stand-alone project, any .cpp and .c files could be compiled correctly, but when i migrated µC/OS-II into the project, I found os_cpu_a.s file couldn't be assembled correctly.
Error logs are shown as follows:
And my Makefile flags setting is:
Please give me some suggestions! Any help will be appreciated!

; CRITICAL SECTION METHOD 3 FUNCTIONS
;
; Description: Disable/Enable interrupts by preserving the state of interrupts. Generally speaking you
; would store the state of the interrupt disable flag in the local variable 'cpu_sr' and then
; disable interrupts. 'cpu_sr' is allocated in all of uC/OS-II's functions that need to
; disable interrupts. You would restore the interrupt disable state by copying back 'cpu_sr'
; into the CPU's status register.
;
; Prototypes : OS_CPU_SR OS_CPU_SR_Save(void);
; void OS_CPU_SR_Restore(OS_CPU_SR cpu_sr);
;
;
; Note(s) : 1) These functions are used in general like this:
;
; void Task (void *p_arg)
; {
; #if OS_CRITICAL_METHOD == 3 /* Allocate storage for CPU status register */
; OS_CPU_SR cpu_sr;
; #endif
;
; :
; :
; OS_ENTER_CRITICAL(); /* cpu_sr = OS_CPU_SaveSR(); */
; :
; :
; OS_EXIT_CRITICAL(); /* OS_CPU_RestoreSR(cpu_sr); */
; :
; :
; }

By the way, it seems that any chinese character in edition will be treated as spam as a spam prevention method?So i have to delete all chinese comment in my code.
My app make a telephone call from my collection view controller. After the call app shows home page. Call is not returned to called controller.
I put break points and checked execution flow. Then I could realise that call returned to called controller. But after that some internal codes are running and automatically segue to home page view controller (initial view controller). I don't know anything about internal execution like
UIKit-[UIControl sendAction:to:forEvent:]:
0x1891f93b4 <+0>: stp x22, x21, [sp, #-48]!
0x1891f93b8 <+4>: stp x20, x19, [sp, #16]
0x1891f93bc <+8>: stp x29, x30, [sp, #32]
0x1891f93c0 <+12>: add x29, sp, #32
0x1891f93c4 <+16>: mov x19, x4
0x1891f93c8 <+20>: mov x20, x2
0x1891f93cc <+24>: mov x21, x0
0x1891f93d0 <+28>: mov x0, x3
0x1891f93d4 <+32>: bl
Finally I could track my problem..For some other reason I put a line of code inside the following App delegate method like:-
func applicationWillResignActive(application: UIApplication) {
window?.rootViewController?.dismissViewControllerAnimated(false, completion: nil)
}
I commented the line of code and everything work fine...Thank God!!!!!
