LNNotificationCenter invalid cast the notification settings from userdefaults as NSDictionary instead of NSMutableDictionary

[ItamarM]

In LNNotificationCenter.m

// While _notificationSettings type is NSMutableDictionary the following method will return NSDictionary
_notificationSettings = [[NSUserDefaults standardUserDefaults] valueForKey:_LNSettingsKey];
if(_notificationSettings == nil)
{
_notificationSettings = [NSMutableDictionary new];
}
