What is a PASS file?
A PASS file is a directory that contains all the source files for an Apple Wallet pass. Developers create PASS directories and add files to them in Apple Xcode. They then use the PASS directory to build a distributable Apple Wallet pass (.PKPASS file).
Apple Xcode is an IDE developers use primarily to create and update iOS and macOS apps. Developers can also use Xcode to create distributable Apple Wallet passes. The first step in creating a pass is to create a directory that holds all the pass's source files. This directory always uses the .pass extension.
PASS directories contain the following files:
- A pass.json file that contains the text shown on the pass and the pass's metadata
- Images (typically .PNG files) used as icons, logos, and other pass visual elements
- Localization information
After they've finished developing their pass, developers build the pass and package it into a signed bundle. This bundle is what is distributed to Apple Wallet users, in the form of a PKPASS file.
How to open a PASS file
PASS directories are meant to be opened in Apple Xcode (Mac). Opening the directory in Apple Xcode will allow you to view the pass creation project it contains, and all its constituent files, in an organized manner.
