Apple has released Pass Designer, a new tool for building passes that live in Apple Wallet, such as boarding passes, event tickets, loyalty cards, and gym memberships. Instead of hand-writing JSON pass files and guessing how they will render, developers now get a visual editor with a live, accurate preview. This matters because Wallet passes are a common integration point for airlines, retailers, event venues, and transit systems, and getting the design and data structure right has historically required trial and error.

What Pass Designer actually does

Pass Designer is built around templates, either ones provided by Apple or custom templates created by a business. Developers bring in their own visual assets — logos, background images, strip images — made in whatever design tool they already use, and then assemble them into a complete pass inside Pass Designer. As changes are made, the tool shows a live preview of how the pass will look on iPhone and Apple Watch.

The key detail is that this preview is not an approximation: it uses the same rendering engine as iOS and watchOS. That means the pass shown inside the design tool is exactly what a customer will see on their device, removing a layer of guesswork that previously required testing on real hardware to confirm.

Basic styling controls are included as well, such as adjusting a pass’s background, foreground, and label colors, along with editing the standard fields each pass type supports directly within the interface.

Built-in validation catches errors early

One of the more practical additions is real-time validation. As a developer edits a pass, Pass Designer checks the structure and flags problems such as missing required key values or unexpected field definitions. For anyone who has previously debugged a malformed .pkpass file by trial and error, this kind of immediate feedback is a meaningful quality-of-life improvement, since pass errors often only surface after a file fails to load on a device.

Semantic tags and structured data

For boarding passes and event tickets specifically, Pass Designer supports semantic tags, which attach structured data to a pass — things like event dates, venue locations, or flight details. This structured data is what powers system-level features such as Siri Suggestions, Calendar integration, and Maps directions tied to a pass. In other words, semantic tags are the mechanism that lets an iPhone proactively suggest leaving for the airport or surface a ticket’s venue on a map, rather than the pass being purely a static image.

Pass Designer lets developers edit these semantic tags directly in the UI and compare a semantic version of a pass side by side with a non-semantic one. It can also automatically generate a backward-compatible pass structure from semantic data, so a single design can still function correctly on systems or Wallet versions that don’t support semantic tags.

How this differs from the previous workflow

Historically, building a Wallet pass meant manually assembling a pass package — JSON metadata, images at the correct resolutions, and signing certificates — largely without a visual feedback loop. Developers would need to install the resulting file on a physical device or simulator to check how it actually looked, and errors in the JSON structure often weren’t caught until that point. Pass Designer consolidates design, data editing, validation, and preview into one workflow, with the preview and validation steps happening continuously rather than after the fact.

The tool also supports both the latest Apple Wallet capabilities and backward-compatible pass designs within the same project, which is notable because it means businesses don’t have to choose between adopting new features and supporting customers on older OS versions.

What this means for developers in practice

For teams that already issue Apple Wallet passes — airlines, transit agencies, event ticketing platforms, retail loyalty programs, coffee chains — Pass Designer should shorten the iteration cycle between designing a pass and confirming it renders and functions correctly. Smaller businesses, like a local gym or a single music venue, get a lower barrier to entry since they can start from an Apple-provided template rather than building a pass structure from scratch.

The tool is currently in beta and requires macOS 27 or later, so it is not yet usable on earlier macOS releases. Access requires signing in with an Apple Account, and if the user has not already done so, completing free registration and accepting the Apple Developer Agreement. There is no indication in Apple’s description of a cost beyond that standard developer registration step.

As with other Apple developer betas, early adopters should expect the tool and its feature set to evolve before a final release, and should treat workflows built around it now as subject to change.

Frequently asked questions

Does Pass Designer replace writing pass code entirely? It centers the process around a visual editor and field-level editing rather than raw file authoring, but it still produces the underlying pass structure, including semantic tags, that integrates with existing Wallet systems.

Can a pass designed with semantic tags still work on devices or Wallet versions that don’t support them? Yes. Pass Designer can automatically generate a backward-compatible version of the pass structure from the semantic data, so the pass still functions where semantic tags aren’t supported.

What do I need to try it? macOS 27 or later, an Apple Account, and completion of free Apple Developer registration if not already done.
