Ionic 4, Cordova & iOS - the app crashes

[ciccilleju]

Hello!

I'm doing an app with Ionic 4 and cordova-plugin-braintree version 0.5.1

With Android everything works fine.

With iOs i'm having trouble making it work:

I can access ythe paypal account, choose the card and the payment method but when i choose to pay the app crashes and i get this error:

this is my AppDelegate file

@implementation AppDelegate

  {
  self.viewController = [[MainViewController alloc] init];
  [BTAppSwitch setReturnURLScheme:@"com.nastydevops.singlefin.payments"];
  return [super application:application didFinishLaunchingWithOptions:launchOptions];

}

  if ([url.scheme localizedCaseInsensitiveCompare:@"com.nastydevops.singlefin.payments"] == NSOrderedSame) {

  }
  return NO;
  }
