However, this is not true for all bundle types. For example, applications and plug-ins are typically presented as a single file by the Finder. All you have to do is create an Xcode project of the appropriate type. For the most part, Xcode takes care of this for you by providing templates that apply the correct extension. The preferred way to specify a package is to give the package directory a known filename extension. The directory has an extension that some other application claims represents a package type see Document Packages. The directory has a known filename extension. The Finder considers a directory to be a package if any of the following conditions are true: ![]() How the System Identifies Bundles and Packages However, not all bundles are packages and vice versa. For example, applications and loadable bundles are packages because they are usually treated as opaque directories by the system. ![]() The reason bundles and packages are sometimes considered to be interchangeable is that many types of bundles are also packages. It also depends on other factors such as the target platform and the type of plug-in. The exact structure of a bundle depends on whether you are creating an application, framework, or plug-in. The presence of this structure also helps facilitate important features such as localization. Bundle files into archive and execute on extract code#Bundles define the basic structure for organizing the code and resources associated with your software. Whereas packages are there to improve the user experience, bundles are geared more toward helping developers package their code and to helping the operating system access that code. The user can use this window to navigate the package's directory structure and make changes as if it were a regular directory hierarchy. Selecting this command displays a new Finder window set to the top level of the package directory. On the contextual menu for package directories is a Show Package Contents command. Note: Even though packages are treated as opaque files by default, it is still possible for users to view and modify their contents. For example, it prevents users from rearranging or deleting resources or code modules that might prevent an application from running correctly. This behavior prevents casual users from making changes that might adversely affect the contents of the package. When you interact with the package directory, however, the Finder treats it like a single file. Inside the package directory are the code and resource files needed to make the application or plug-in run. If you look at an application or plug-in on your computer, what you are actually looking at is a directory. Packages provide one of the fundamental abstractions that makes macOS easy to use. Bundles and PackagesĪlthough bundles and packages are sometimes referred to interchangeably, they actually represent very distinct concepts:Ī package is any directory that the Finder presents to the user as if it were a single file.Ī bundle is a directory with a standardized hierarchical structure that holds executable code and the resources used by that code. This chapter provides an introduction to bundles and discusses the role they play in macOS and iOS. Bundles provide a simplified interface for end users and at the same time provide support for development. Bundle files into archive and execute on extract software#But, how do you split up your file so it can fit on to those two discs? With 7-Zip, that’s how.Bundles are a convenient way to deliver software in macOS and iOS. A CD can hold 700MB of data, so you would need two discs. Say you have a 1GB file, and want to put it on two CDs. Other than that little caveat, self-extracting archives are great. If you’re using 7-Zip to archive some files and send them to a person you don’t know very well, they might be weary of opening the file, and their anti-virus may even issue a warning. exe, click extract, and you’re done unzipping the files.ĭisadvantages – People won’t be too anxious to open up an executable email attachment.
