iOS

In iOS, for opening an external app from your app, you need to provide URLscheme of the target app.

To know more about URLScheme refer to this Link

If your deployment target is greater than or equal to 9, then you also need to update APP-A information in Info.plist.

    <key>LSApplicationQueriesSchemes</key>
    <array>
      <string>APP-B-Scheme</string>
    </array>
