I don't use Test Cloud, would anyone be able to explain in detail what is happening?

IOS 11 Application Crashes When PushKit Receive Push While App is Terminated

Our application started to act weird when ios 11 update is released. We are using pushkit to receive push notifications related with incoming call and messages.
While the app is not in the background(in terminated state), when a push notification arrives IOS raises our app and execute didFinishLaunching method than notification arrives to didReceiveIncomingPushWithPayload method
However after updating to IOS 11 we found out that while the app is terminated sometimes we cannot receive notifications and when we checked the crashlogs we saw that app is crashing and as the reason IOS says cpu usage but it succesfully executes didFinishLaunching method(we put logs to the end of the method and they are printed)
We dont know what may cause this problem, does anyone have any idea about the changes in IOS 11 to trigger that problem
Below you can find our crashlog

We found out that, in ios11 apple reduces the time that is needed to start the application while the app is in background(In our case it was 2.9 seconds), so when you go beyond it, app is automaticaly killed by IOS.
So we find the solution as minimizing the loading times (such as minimizing the splash screens etc..) and also removing the codes which is not neccesarily need to work on background. And we made our app to launch at 1.8 seconds than crash problem is resolved

iPad Native crashes when app resumes back

The iPad app crashes when we idle the app for sometime and then resume it from the lock state, the crash log is shown below the app freezes and to restrat the app we need to do the soft reset to the app

This is an EXC_BAD_ACCESS type of code which relates to accessing deallocated memory. In order to find this you need to enable NSZombie objects. Press Option/alt + Command + R and select the "Diagnostics" tab. Finally, click "Enable Zombie Objects". This should make the compiler stop on the line of code that is causing this crash.

Deciphering a Crash Report - iOS - xCode

I am trying to replicate a bug in my app which is happening for users occasionally. I have the below crash report. Am I right in thinking the app is crashing due to an NSDictionary not having a value for a specific key ? And is there anything else I can deduce from the report ?

Code which is crashing :
- (void)_sendData:(NSDictionary *)data responseCallback:(WVJBResponseCallback)responseCallback handlerName:(NSString*)handlerName {
NSMutableDictionary* message = [NSMutableDictionary dictionaryWithObject:data forKey:#"data"];
if (responseCallback) {
NSString* callbackId = [NSString stringWithFormat:#"objc_cb_%ld", ++_uniqueId];
_responseCallbacks[callbackId] = [responseCallback copy];
message[#"callbackId"] = callbackId;
}
if (handlerName) {
message[#"handlerName"] = handlerName;
}
[self _queueMessage:message];
}

The crash happens in the file WebViewJavascriptBridge.m in line 95 in the method [WebViewJavascriptBridge _sendData:responseCallback:handlerName:].
That line causes an exception in [__NSPlaceholderDictionary initWithObjects:forKeys:count:]. Since the exception message isn't shown in the crash report, and you don't provide any source code of that place we can only assume what is happening.
One assumption would be, your are creating a dictionary with nil values or keys. But without code or you actually debugging this, this is only an assumption.

iPhone app using Facebook SDK crashes with "has active assertions beyond permitted time" error

I have an iPhone (iOS native) app that uses the current Facebook iOS SDK. When attempting to connect my app via the Single-Sign-On process, I frequently get a crash stating my app "has active assertions beyond permitted time". After reviewing other similar reports here on Stack Overflow (such as iPhone app "has active assertions beyond permitted time") I don't find anything that seems to fit my situation. I am following Facebook's recommended practices for integrating SSO (from https://developers.facebook.com/docs/mobile/ios/build/#implementsso). That means I am calling the Facebook SDK on my main thread. Facebook doesn't seem to think this will be a problem.
Can anyone explain what this particular error means? I assume that some iOS supervisor mechanism is killing my app because it's taking too long doing something, but what particular something? Is it because the foreground task is locked for too long? Or what?
Here's an iOS app crash report showing the error.

Unknown thread crashed with unknown flavor: 5, state_count: 1

I finally tracked this down. Just as in other similar incidents reported on Stack Overflow, this turned out to be a problem with a scheduled operation attempting to run in the background. My problem is resolved.
