Bundles, which represent executables of different kinds, contain an information property list file. This collection of key-value pairs specifies how the system should interpret the associated bundle. Some key-value pairs characterize the bundle itself, while others configure the app, framework, or other entity that the bundle represents. Some keys are required, while others are specific to particular features of the executable.
The information property list file always has the name
Info. The file name is case-sensitive and must begin with a capital letter
I. Its location within the bundle depends on both the bundle type and the platform. For example, iOS app bundles store the file in the bundle’s root directory, whereas macOS app bundles place the
Info file in the
To access an information property list, you use an instance of the
NSBundle class, which represents a bundle on disk. You can get the value for a few common keys by accessing properties of the bundle instance. For example, the
bundle property contains the value associated with the
CFBundle key. You can obtain the value for an arbitrary key using the
To create an information property list for a bundle, you typically rely on Xcode to prepare the file for your apps and other executable targets, as described in Managing Your App’s Information Property List.
