What is a .PASS file?
A .PASS file is a special folder used by developers who are making passes for the Apple Wallet. The Apple Wallet is an app on iPhones and other Apple devices where you can keep things like boarding passes, movie tickets, and coupons. The .PASS file contains all the different pieces needed to make one of these passes, like images, text, and information on how the pass should work.
Developers put together these .PASS files using a program called Apple Xcode. Xcode is a tool for creating apps and other software for Apple devices. Once the developers have all the parts they need in the .PASS file, they use Xcode to turn it into a .PKPASS file. The .PKPASS file is the final version that can actually be added to the Apple Wallet and used by people.
So, if you come across a .PASS file, it's likely part of the process of making a digital pass for the Apple Wallet. To open or work with a .PASS file, you would need to use Apple Xcode, which is available for Mac computers.
