Linking.addEventListener not working: url event never fires

Description

Url event never fires

I followed the indicated setup to handle deep links in react native.

But when I have the app open in background or foreground and I execute command npx uri-scheme open "mychat://bar" --ios, url event doesn’t fire.

I saw there is a similar issue in react-navigation, but the fix indicated for AppDelegate.m doesn’t work for me.

Version

0.76

Output of npx react-native info

Yes, I do follow the document but still fail. I can’t run in simulator, so I use browser with button to call the url scheme. if app is closed, it works fine. But if app is in background, the url scheme called just bring app to foreground, but the url listener is not fired. My RN is 0.68.2, older than yours. Will this be a problem? By the way, can your app receive url event when it is in background?

Hi @edwardhsueh, I was using react native 0.68.0 and facing the same problem One thing that you can try is adding the below code to the location that specified by React Navigation Documentation as I am not familiar with Swift and placing the code in the wrong location

// Add the header at the top of the file:
#import <React/RCTLinkingManager.h>

// Add this inside `@implementation AppDelegate` above `@end`:
- (BOOL)application:(UIApplication *)application
   openURL:(NSURL *)url
   options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
  return [RCTLinkingManager application:application openURL:url options:options];
}

It’s working for me now
