Dynamic configuration is a convenient way to adjust the properties of your executable without recompiling your code. Rather than relying on hardcoded information, your application implements slightly different behaviors based on external settings. There are several ways to record these settings, ranging from user preferences to property lists stored with your bundle.

Bundles use property lists extensively to store information about the bundle and its contents. macOS and iOS use the information in these property lists to determine an application properties such as its icon and whether to show the status bar (for iPhone applications).

You should read this document to learn about the properties you can use to configure application behavior and specify how macOS or iOS handle your application.
