My app has been rejected from Apple quite a long time now.
They say that I get crash on dashboard but although it works fine on simulator and device
I implemented 2 approaches to get the crash report
Firebase Analytics
Symbolised the crash reported shared by Apple.
.init(coder:)
It says error generated by compiler
8 SSBS 0x10521c174 DashboardViewController.init(coder:) + 5308788 (<compiler-generated>:0)
9 SSBS 0x10521c238 #objc DashboardViewController.init(coder:) + 5308984 (<compiler-generated>:0)
In this case, what do I need to implement in my ViewController Class file
So the crash report generated fr
om that is :

//navigationHeaderItem()
// Do any additional setup after loading the view.
if(self.isNewDashboard == nil || self.isNewDashboard == true){

I initiate a view controller like:
let vcObj = self.storyboard?.instantiateViewController(withIdentifier: "DashboardController") as! DashboardViewController
vcObj.isNewDashboard = true
self.navigationController?.pushViewController(vcObj, animated: true)
Am I am missing anything here?

Not very much accustom to Objective C, hence trying to observe NSWorkspaceDidActivateApplicationNotification event in C++ code with CFNotificationCenterAddObserver() method.
#include<CoreFoundation/CFNotificationCenter.h>
#include<iostream>
#include<QGuiApplication>
void Callback (CFNotificationCenterRef center, void* observer, CFNotificationName name,
const void* object,
CFDictionaryRef userInfo)
{
std::cout << "Hello World\n";
//NSLog(#"New application: %#", [[name userInfo] objectForKey:NSWorkspaceApplicationKey]);
}
int main (int argc, char** argv)
{
QGuiApplication application(argc, argv);
std::cout << "Add observer\n";
CFNotificationCenterAddObserver(CFNotificationCenterGetDistributedCenter(), nullptr, Callback,
CFStringRef("NSWorkspaceDidActivateApplicationNotification"), nullptr,
CFNotificationSuspensionBehaviorDeliverImmediately);
std::cout << "Added ...\n";
return application.exec();
}
However it results in below crash. If I try to run in debug mode, then it sometimes shows the below crash or sometimes get stuck in that function itself.

libc++abi.dylib: terminating with uncaught exception of type NSException
How to fix this?
Use CFSTR macro to create a CFStringRef from a constant C string like so:
CFSTR("NSWorkspaceDidActivateApplicationNotification")
NSWorkspaceDidActivateApplicationNotification docs says that you have to use NSWorkspace.notificationCenter to receive it, CFNotificationCenterGetDistributedCenter won't work.
I have view that uses .sheet() to present modally some another ChildView
I want to dismiss ParentView when this sheet is dismissed. So there is onDismiss callback.
However when I add
#Environment(\.presentationMode) var presentationMode
then presenting sheet it crashes with such bug
libc++abi: terminating with uncaught exception of type NSException
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Application tried to present

Without using this environment property everything works ok.
It seems that sheet tries to present itself multiple times then this property is available.
But on other screens (views) everything works ok.

Sample code looks like this
struct ParentView: View {
#Environment(\.presentationMode) var presentationMode
var body: some View {
mainButton
.sheet(
item: $viewModel.item,
onDismiss: {
},
content: { summary in
ChildView()
}
)
}
}
Ok I found solution. What was causing the problem was that when there is Environment(.presentationMode) there is some refreshing done on this view
.sheet(item:) relies on Identifiable type that requires id.
It has this id but if it used optional identifier with like
var id: String { myId ?? UUID().uuidString }
When there wasn't this Environment this underlying model id doesn't change but with Environment property underlying item model has recalculated id and it was causing problem by trying to present this view double times.
the audio unit subType is kAudioUnitSubType_VoiceProcessingIO,
and use kAudioOutputUnitProperty_CurrentDevice to set Device ID for the audio unit
OSStatus result = AudioOutputUnitStop(audio_unit);
result = AudioUnitUninitialize(audio_unit);
result = AudioComponentInstanceDispose(audio_unit);

You are disposing of an Audio Instance before it is stopped.
Note that AudioOutputUnitStop may not stop an audio unit immediately, since the audio thread runs asynchronously. If you delay for a half second after stopping the audio unit, that other thread is likely stopped by then and then you can more safely dispose of its resources.
I have Cocos2d app that fail randomly for some user when i try to display a CCLabelBMFont with animation. I'm not able to reproduce the issue on any of my test device. Since it seem to fail on line 845 I'm wondering if I'm runing out of mmemory. I'm using cocos2d v2.0.0.
for (TileBlockModel* tile in [matchInfo tiles]) {
if (tile.matchScore > 0 && tile.spriteObject != nil) {
NSString* str = [NSString stringWithFormat:#"%d",tile.matchScore];
CCLabelBMFont* label = [CCLabelBMFont labelWithString:str fntFile:#"8-WHITE NUMBERS.fnt"];
label.position = ((CCNode*)tile.spriteObject).position;
label.scale = label.scale * fontMultiplier;
label.zOrder = TILE_BLOCK_SCORE_Z_LEVEL;
[gameGrid addChild:label];
CCActionInterval* action = [CCSequence actions:
[CCMoveBy actionWithDuration:.4 position:ccp(0, ((CCNode*)tile.spriteObject).boundingBox.size.height)],

Hi everybody i am trying to make a boolean method that will return value depending upon the user input for the field when submit button is clicked.
- (BOOL)checkuser:(NSString*)input
{
bool result = NO;
if ([input isEqualToString:#"test"])
{
result = YES;
}
else
{
result = NO;
}
return result;
}
And i am refrencing this method from my program as
else if ([Username checkuser] == YES)
{ // do something
}
with following warning
'NSString' may not respond to '-checkuser'
and i am not getting why my program crashing at this point with following error.

You're over-complicating a very simple problem:
- (BOOL) checkuser:(NSString*)input {
return [input isEqualToString:#"test"];
}
and then to call it:
if ([Username checkUser:#"DONT FORGET YOUR PARAM HERE"]) {
// Do something...
}
In your example, you're not passing any parameter to your method... That's a misstake hence your error.
Also, if you create a method returning a 'BOOL', make sure you're returning a 'BOOL' and not a 'bool'. You have to always keep in mind that the underlying types can be different, even if a bool can be evaluated to a BOOL.
else if ([Username checkuser] == YES)
checkuser is supposed to receive a NSString*, which you are not sending though and is the reason for error messages. So, it should be -
Assuming someNSString is initialized and is of type NSString*.
else if( ([Username checkuser:someNSString] ) == YES )
// ^^^^^^^^^^^^ Needs to be passed as the method prototype mentions so.
{
// ....
}
NSString* someNSString = #"Forgot to pass this" ;
else if( ([Username checkuser:someNSString] ) == YES )
// ^^^^^^^^^^^^ Needs to be passed as the method prototype mentions so.
{
// ....
}
