bms-push cordova plugin on iOS gives: fatal error: unexpectedly found nil while unwrapping an Optional value

I've implemented an Ionic test application using the new bms-push cordova plugin.

It works fine on Android.

However, when launching the app on iOS, it immediately fails with:

fatal error: unexpectedly found nil while unwrapping an Optional value

The error occurs in the didReceiveRemoteNotificationOnLaunch function of the CDVBMSPush class.

If I comment out the following line in the AppDelegate.m

[[CDVBMSPush sharedInstance] didReceiveRemoteNotificationOnLaunchWithLaunchOptions:launchOptions];

then the app starts properly.

Any suggestion to fix the problem please? Thx

Just got an answer from the support team:

[[CDVBMSPush sharedInstance] didReceiveRemoteNotificationOnLaunchWithLaunchOptions:launchOptions];

This is only used when app is opened by clicking push notifications.

At the first time launchOptions will be nil. That why its failing.

Solutions:

1. you can add a check there whether the launchOptions is of type remoteNotificationKey, If yes then add the [[CDVBMSPush sharedInstance] didReceiveRemoteNotificationOnLaunchWithLaunchOptions:launchOptions];

Example:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    if (launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]) {
      [[CDVBMSPush sharedInstance] didReceiveRemoteNotificationOnLaunchWithLaunchOptions:launchOptions];
    }
}

2. Completely remove that line of code.
