Hello! You can. The way you do it is you put the Metal Shaders in txt files. One of my friends who got distinguished last year did things this way. I'll ask him how he did it specifically and will let you know. Good Luck!

@Claude31 answered everything well. I’d add that it’s valuable to mention features you plan to build, even if they’re only partially implemented. The project’s idea makes up roughly two-thirds of the criteria, while technical accomplishment is just one-third. So even if it isn’t perfect, include it and explain where you see the app going next. Make sure to mention your future plans in your essay as well. Good luck!

Hello! This sounds like an awesome idea. One of my previous submissions was a study app that tracked screen time while someone was studying. I looked into the Screen Time API, but it’s pretty limited in Swift Playgrounds, so I simulated the behaviour in the app to show judges what it was intended to do. You don’t need everything working 100%. Clearly explaining the idea is a great first step. On the video/animation side, that’s a great addition. I included some in my submission that won last year. Just make sure you’re not using any copyrighted material you don’t have rights to in your video or infographic. They’re not just looking at the app and code, they care about your creative process. In my case, I mentioned that I hand‑drew the artwork in Procreate and animated it in Procreate Dreams. You want to emphasize the care and consideration you put into the submission. Regarding tracking: the rules are about not tracking judges on their devices without their knowledge or sending that data to a server. Using native Apple APIs to inform users about their habits should be fine.

Hello! I’m not a Distinguished Winner, but I did win last year. In my experience, it takes time. For examples of strong projects, see https://wwdcscholars.com/ (not endorsed by Apple). It showcases many past winners and helps you understand what judges look for. Don’t expect to win on your first try. It’s competitive, and I needed two failed attempts before a winning submission. I focus on the intersection of my interests, problems I’ve identified, and native Apple technologies. That keeps me motivated by the problem I’m solving. Remember that the app is only part of the challenge. Don’t underestimate the essay. Make sure your app and essay reflect who you are as a developer. In my experience, judges care more about your motivations and the problem you’re tackling than a perfectly polished solution. The idea is the most important part, and it often takes the longest. This year, I went through three different ideas before landing on one I’m happy with. Hope this helps, and good luck!

Framework compatibility: My app uses Foundation Models and Apple Pencil. The app runs great through Xcode; however, due to Apple Pencil support, it has to be run on a physical device. However, Swift Playgrounds on iPad doesn't support iOS 26. I was just wondering if this is something that can be mentioned in submission notes. eg. The app needs to be compiled in Xcode but run on a physical device.” Or should we expect iPadOS 26 support for Swift Playgrounds by the time of submission? Thank you!

same issue here just only in Xcode 13
