unable to check app is installed or not

[ignivanishant]

i use this package my code is
import { AppInstalledChecker, CheckPackageInstallation } from 'react-native-check-app-install';

and inside render() i just put

AppInstalledChecker
.isAppInstalledIOS('facebook') // omit the :// suffix
.then((isInstalled) => {
console.log("isInstalled ", isInstalled);
// isInstalled is true if the app is installed or false if not
})

it always return false weather app is installed or not as you can see in code i am checking for facebook

I think on iOS, since version 9, you have to whitelist URL schemes before you can use them. This plugin uses URL schemes to check if apps are installed. Can you add fb to the array LSApplicationQueriesSchemes in Info.plist in your iOS project. Similar to this:

Please let me know if that fixes it so I can update the installation instructions.

same here i added the urlScheme for googlemaps to info.plist but return false allways

@DanGDroid in think you must restart the app in the xcode.

@DanGDroid did treemore's fix work for you? Can I close this issue?

@redpandatronicsuk 's solution fixes the issue. @DanGDroid just re-run the app and it'll work!

i added the urlScheme for Instagram, Facebook and restart the app in the Xcode....But it still return false weather app is installed or not.

i ended up using Linking.canOpenURL(appUrl.urlScheme)
