What are the main types of goals (targets) in iOS app development?

In iOS development, 'targets' refer to separate build configurations within a single Xcode project that allow creating different versions of the app or related products. Main types of targets:

• App Target — the main application that will be installed on the device.
• App Extension Target — app extensions, such as widgets, keyboards, notifications, which operate in the context of the main app but have a separate lifecycle.
• Framework Target — creating libraries and frameworks that can be used across multiple applications.
• Unit Test Target — targets for modular code testing.
• UI Test Target — targets for user interface testing.

Using different targets allows managing the build, resources, and settings for various versions of the app (e.g., free and paid versions).
