   buildscript { 
       repositories {

       } 
       dependencies { 
           classpath 'com.android.tools.build:gradle:3.5.3'

   } 
    
   allprojects {

   - (BOOL)Application:(UIApplication *)Application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions { 
   // Override the code for customization after app launch.
