It is also a common behavior for native apps to communicate between one another via linking, and are usually prompted to the user with the phrase Open in..., along with the name of an app that can better handle an action. This is done by using a protocol that is specific to your app. Just like any website link has a protocol of either http:// or https://, we can also create a custom protocol that will allow any other app to open and send data to our app.
In this recipe, we will be creating a custom protocol called invoked://. By using the invoked:// protocol, any other app can use it to run our app and pass data to it.
