As the title says, my app immediately crashes when run if there is no internet connection/airplane mode is on. The thing is, when I set breakpoints it doesn't even make it to any of my code. Not a single viewDidLoad or even AppDelegate function gets called, and the error message doesn't seem like something that would be related to not having a network connection:

I really have no clue what it could be. Tried setting a symbolic breakpoint at [UIViewController _loadViewFromNibNamed:bundle:] but that didn't really give any useful insight. Hope someone can help. I should also mention the only thing I'm doing in AppDelegate is instantiating firebase.
Helpful guy over at reddit figured it out for me. Didn't realize but there was an init() function on my initial view controller that the last guy made which checked the internet connection and redirected to a different page if there wasn't one.

Other information:
this crash mostly appear at the launching of the App.
read the code stack, the crash probably takes place when user's keyboard is using.
I can't solve this crash because I don't have enough clues and the code stack doesn't have any my App code, only system code.
Any clue about this crash is appreciate. Thank you.
What's interesting thing is, this crash takes place on time everyday, just 5pm to 8pm(Beijing time). We can not see any one crash takes place at other time in a day. A weird crash!
I'm very new to the App Store Validation process, and I'm getting a crashes in their testing that do not happen in Simulators or real device testing. This seems to be common story.
Here's the relevant part of the latest crash log from Apple:

This a fairly simple question, but I want to be sure... the last line corresponds to the start() method in my initialization process, and I presume the the + 4 is the fourth line of code in that code block? And I also presume that that includes commented lines in my original code?
If so, and that line sets a property of an optional instantiated class, then I assume a crash at this line would indicate that there was a problem with that object, but that the object would not appear in the crash log, since it wasn't one of its methods that was called. Correct?
I'm trying to connect an existing AppSync API to my iOS app.
To perform this, I followed the instructions on this page: https://docs.amplify.aws/cli/graphql-transformer/codegen#ios-usage, but instead of performing:
amplify add api
amplify push
I added my existing AppSync API:
amplify add codegen --apiId XXXXXXXXXXXXXXX
amplify codegen
After running those commands, I added awsconfiguration.json and API.swift to my project.
After performing the setup, I initialized the AppSync client in the AppDelegate file:
import AWSAppSync
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var appSyncClient: AWSAppSyncClient?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
do {
// You can choose your database location if you wish, or use the default
let cacheConfiguration = try AWSAppSyncCacheConfiguration()
// AppSync configuration & client initialization
let appSyncConfig = try AWSAppSyncClientConfiguration(appSyncServiceConfig: AWSAppSyncServiceConfig(), cacheConfiguration: cacheConfiguration)
appSyncClient = try AWSAppSyncClient(appSyncConfig: appSyncConfig)
} catch {
print("Error initializing appsync client. \(error)")
}
}
}
It's worth mentioning that I'm using AWS SDK (for DynamoDB using Object Mapper) in my app (the previous SDK, not Amplify yet)
The problem is that when I'm running the app, it immediately crashes.
This is the log message that comes along with the crash:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'The service configuration is `nil`. You need to configure `Info.plist` or set `defaultServiceConfiguration` before using this method.'

Apparently, because I'm using the old version of AWS SDK for iOS, I couldn't use both awsconfiguration.json file and the AWS section in Info.plist file.
In order to solve it, I removed the awsconfiguration.json file from Build Phases -> Copy Bundle Resources, and added the AppSync API details from that file to the Info.plist file:
<key>AWS</key>
<dict>
<key>AppSync</key>
<dict>
<key>Default</key>
<dict>
<key>ApiUrl</key>
<string>https://XXXXXXXXXXXXX.appsync-api.xx-xxxx-x.amazonaws.com/graphql</string>
<key>Region</key>
<string>xx-xxxx-x</string>
<key>AuthMode</key>
<string>API_KEY</string>
<key>ApiKey</key>
<string>XXXXXXXXXXXXX</string>
<key>ClientDatabasePrefix</key>
<string>XXXXXXXX_API_KEY
</dict>
</dict>

I am using fetchRequestTemplate with NSPredicate to get data. I get "Thread 1: signal SIGABRT" on the following bit of code:
fetchRequest.predicate = NSPredicate(format: "userID == %#", userID)
Here is the full description of the problem:

If you are having this error when using Xamarin Forms you should probably check if your initial page is properly constructed. This happens when XF fails to create your initial page and just continues running.
