Plugin Version

"react-native-appsflyer": "^6.5.21", "react-native": "0.68.1",

On what Platform are you having the issue?

ℹ ios

What did you do?

ℹ Was following "Measure App Uninstalls" guide here: https://github.com/AppsFlyerSDK/appsflyer-react-native-plugin/blob/master/Docs/AdvancedAPI.md#-measure-app-uninstalls

What did you expect to happen?

ℹ code snippet not to throw errors on every line

What happened instead?

line @import AppsFlyerLib; throws: Use of '@import' when C++ modules are disabled, consider using -fmodules and -fcxx-modules rest of snippet:

- (void)application:(UIApplication ​*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *​)deviceToken {
// notify AppsFlyerLib
 [[AppsFlyerLib shared] registerUninstall:deviceToken];
}

this snippet throws multiple errors: 1: Expected ')' 2: Interface type 'UIApplication' cannot be passed by value; did you forget * in 'UIApplication'? Insert '*'

second error is auto-fixable, after pressing "fix" button, it resolves. But the rest of errors persist.

also throws warn: 1: Identifier contains Unicode character <U+200B> that is invisible in some environments

Please provide any other relevant information.

try to remove @import AppsFlyerLib; and use the code suggested by XCode for didRegisterForRemoteNotificationsWithDeviceToken.
