Before developing an iOS app, you'll need to register the app ID on the Apple developer website
The App ID consists of:
APP ID Prefix (prefix) + '. ' + App ID Suffix (suffix)
Where the prefix is assigned by Apple to identify different developers, also called Team IDs,
Suffix, also called bundle ID, is a developer's custom identifier, similar to the package name in Andriod development,
General use of domain name reversal style:
Com.test.myapp
It is important to note that in iOS development, app IDs can be shared by multiple apps, which is not the same as Android.
For example, we can set the bundle ID to:
com.test.*
This enables the public of the app ID.
When registering the app ID, you can also select some services (app services),
such as information push (push notifications), in-app payments (In-app Purchase)
This way, you can use Apple's services in the app.
