Answer 1

Вы можете детерминированным, если какой-либо вид применения устанавливается с помощью этого кода (просто заменить customURL очевидно в течение других приложений):

 NSString *customURL = @"googlegmail://"; 

     if ([[UIApplication sharedApplication] 
     canOpenURL:[NSURL URLWithString:customURL]]) 
     { 
      [[UIApplication sharedApplication] openURL:[NSURL URLWithString:customURL]]; 
     } 
     else 
     { 
      //not installed, show popup for a user or an error 
     } 

Answer 2

Your library was compiled without bitcode, but the bitcode option is enabled in your project settings. Say NO to Enable Bitcode in your target Build Settings and the Library Build Settings to remove the warnings.

For those wondering if enabling bitcode is required:

Примечание: Для IOS приложений, является битовым кодом по умолчанию, но необязательно. Если вы предоставляете биткод, все приложения и фреймворки в комплекте приложений должны включать бит-код. Для приложений watchOS требуется биткод.
