Apple's Pass Designer Needs macOS 27 and Saves Templates, Not Passes; Pass Builder Still Does the Signing

Apple's Pass Designer, a Mac app for building Wallet passes, requires macOS 27 and saves templates rather than finished passes, so a second tool, Pass Builder, still has to sign every one that customers receive.

The app was announced at WWDC in June, per the WalletWallet and heise accounts below, and Apple's Pass Designer page reached 313 points on Hacker News on October 3. Apple lists no release date for the app itself, only the macOS 27 requirement.

What the app does

Apple describes a WYSIWYG editor that renders a pass with the same code as iOS and watchOS, with previews for iPhone and Apple Watch. It starts from Apple's templates or your own, imports logos, backgrounds and strip images from design tools, and validates the pass as you work, flagging missing required keys and unexpected definitions.

Boarding passes and event tickets get semantic tags: structured data such as event dates, venue locations or flight details, which the system uses for Siri Suggestions, Calendar and Maps directions. Apple says the app can also generate a backward-compatible pass structure from that semantic data.

Heise's report, published June 22, lists boarding passes, coupons, event tickets, loyalty cards, generic passes and poster passes among the templates, and puts the download at about 20 MB. It also advises testing the beta on separate hardware, because of known bugs.

Templates, then Pass Builder

The output is a .pkpasstemplate file with placeholders for per-customer values. Turning one into a distributable .pkpass is the job of Pass Builder, which Apple's Wallet documentation calls "a Swift on server package that lets you programmatically create and distribute passes for Apple Wallet", with "a type-safe API for building and signing Wallet passes".

The developer-tools vendor WalletWallet, which sells a competing pass API, wrote up the pair. Its account adds a buildpass command-line executable, Java bindings and protobuf definitions for other languages, and four new barcode formats: EAN-13, Code 39, Codabar and ITF. It also lists a new Poster Generic style for full-bleed artwork. Those details come from a competitor's reading; the Apple pages fetched for this story do not repeat them.

Piece	Does	Does not
Pass Designer	Edits and previews templates on macOS 27	Sign or distribute passes
Pass Builder	Fills templates and signs .pkpass files	Host servers or send updates

What neither tool covers

WalletWallet's list of gaps is the part that matters for anyone running a loyalty scheme: neither tool manages Apple Developer accounts or certificate lifecycles, hosts anything, handles pass updates or APNs push notifications, or integrates with Google Wallet. That is the author's reading, not an Apple statement, so check it against Apple's documentation before relying on it.

For a small business the sticking point is the signing step. A design can now be previewed exactly as iOS will draw it, but a certificate, an identifier and a server that fills in names and balances remain yours to arrange. Heise says the app helps with creating certificates and identifiers, which sits awkwardly with WalletWallet's statement that certificate lifecycle is out of scope, so the two accounts differ on how much of that Apple covers.

Who can download it, and when

The sources disagree on access. Heise says registered developers can download the beta. WalletWallet says it is free with an Apple Account. Apple's page says only that the app is in beta and needs macOS 27.

The macOS 27 requirement is the real limit: heise expects the general release in autumn 2026 alongside macOS 27, which it calls "Golden Gate". Until then, design work means running a developer beta of the operating system. For context on how Apple is tightening what Mac apps can do after that release, see our report that macOS Full Disk Access will require "very explicit user action". Teams that build no-code tools should also read how Mozilla's Solo shutdown handled export.

Apple has not said when Pass Designer leaves beta; the date to watch is the public macOS 27 release.
