A special directory with an internal structure organized according to standard rules.
IOS applications are encapsulated by bundle, and the corresponding bundle type is Application. Normally, the Target (the Application we developed) compiled by XCode is used ), it is actually a bundle of the Application type, that is, a folder! However, the Finder will display the bundle as a file because the bundle itself is also a package, and the Mac system will treat all the packages as a file and display them to users, this prevents program files from being damaged or lost due to misoperations. The difference between bundle and package is not described here. The bundle mentioned later in this article will be regarded as package by the Mac system.
