Handle URL scheme react-native and Swift

Question

I would like to handle custom URL scheme in my react-native application. Thus I first added an eventListener in my JS code inside my root component like that :

componentDidMount() {
    Linking.addEventListener('url', this.handleOpenURL);
}

componentWillUnmount() {
    Linking.removeEventListener('url', this.handleOpenURL);
}

handleOpenURL = event => {
    console.log('event', event);
};

In my Xcode application, I added a custom URL scheme "com.myScheme".

My problem has appeared when I tried to add the function in my AppDelegate.swift to handle deep linking.

Here's my function :

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool {
    print(url)
    return true
}

It seems that return true is not enough to trigger my listener inside my application ...

I know there's an Objective-C method in the react-native documentation :

#import <React/RCTLinkingManager.h>

- (BOOL)application:(UIApplication *)application
   openURL:(NSURL *)url
   options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
  return [RCTLinkingManager application:application openURL:url options:options];
}

But I would like to deal only with Swift for my project in order to improve my skills in this language. The problem is I can't find any example of this function implemented using Swift.

That's why I'm asking some help to implement this method and then trigger my event inside my RN application.

Thank you for your understanding :)

Regarding your AppDelegate method, the swift version should be :

public func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    return RCTLinkingManager.application(app, open: url, options: options)
}
