The trio are together once more! This week, Steve and Kotaro discuss Steve's most recent HTTP API Client design, some of which was inspired by Rob Napier's "Generic Swift" talk from several years ago. Then, Steve almost loses his voice trying to poorly explain The Composable Architecture (TCA), but does go into some depth on the pieces and ideas he has applied to real world projects. It's mostly Steve talking this week, but it's pretty interesting stuff. Be sure to check the show notes for links so you can dive deep into these topics yourself!

Kotaro hosts solo one more time this week to briefly talk about "secret sauces." No, not the kind you use on nuggets! It's that ineffable quality of an app that makes you love it vs those annoying anti-patterns often prevalent in apps created just to catch the wave of a hype cycle. Kotaro wants to make apps he loves and that you might love, too! This is a short, but practical and personal essay celebrating some apps that found their "secret sauce."

## Topics Discussed:

- Introductions

- iOS 17 is out

- Xcode 15 is out!

- To continue work on visionOS keep Xcode 15 Beta 8 around.

- New iPhones out. Dynamic Island is available across the board.

- What is the secret sauce in an app that makes you love it?

- Hype cycle

- Generative AI

- AR/VR

- Crypto

- How can I make a cool app with these? Lots of bad ideas

- Personal favorites:

- Modo

- SoundStudio

- Sketch

- Procreate (also Procreate Pocket)

Kotaro is solo this episode due to scheduling issues around the end of summer holiday festivities. But, fear not, this episode is short, but jam packed with advice about opportunities for your next big app as we move into the iOS 17/visionOS world. Widgets, AI, visionOS, Macros, and more! There are so many cool new features in this next generation of updates that can lead to brand new opportunities for success in your developer journey...if you read the tea leaves.

## Topics Discussed:

- Introductions

- Episode 50

- visionOS status and personal

- Xcode Beta 8!?

- Reading Apple’s tea leaves and looking for opportunities for your next big app.

- Obvious leaves:

- Widgets Everywhere

- AI in plain site

- CoreML/CreateML make it easier to consume and create custom models.

- visionOS

- ARKit/RealityKit

- SharePlay

- Freeform as a example has an app that came out of nowhere but is now the key app to demonstrate what Apple intends for SharePlay to be utilized.

- Not-so obvious ones:

- DocC

- Better documentation and deeper long term integrations

- SwiftData

- Easier to implement and work with CloudKit sync

- Macros

- Easier to wrap complex templates inside a macro

- Interactive Widgets

- Standby mode becomes more interesting

- CarPlay might be more useful

- Implementation of visionOS version

The trio gather to hear about Steve's Baltimore e-scooter adventure and the app experience. Then, a brief discussion of Xcode Beta 7 before diving into inspiring visionOS demos found on social media. Multiple bad app ideas are entertained this week, including one based on a classic Kids in the Hall sketch. Kotaro goes into some detail on how hand gesture recognition works today and how it might work in the future while Aaron describes our dystopian nightmare future of inescapable avalanches of ads in immersive environments. Ending on a positive note, the Trio wonder if "spatial computing" could usher in a new era of developer experiences. One More Thing...GetClipDish.com!

The trio continue exploring visionOS despite ongoing beta challenges. Steve updates his experiment with a little more functionality while Kotaro scans a "mutant peach" into a 3D object, and Aaron is stymied in his physics experiments due to inadequate Simulator support. Kotaro provides some insights into what game developers may find familiar and frustrating if they decide to venture into visionOS development before discussing some "hot shader action" coming to SwiftUI in iOS 17. Finally, Bad App Ideas returns, revisiting "Portal Pigeons," and we give a shout-out in our "Not a Sponsor" segment to Happy Scale!

The trio continue to suffer the Beta Blues, but Steve did do his pod homework this round and made a very janky visionOS prototype that lets you apply a pixelation filter to a photo! This leads into some good discussion of photo app features that would be appropriate on visionOS interspersed with some "bad app ideas," a digression about Share Play, and Kotaro & Aaron decide they want to build Cerebro! It's an easy-breezy episode, perfect for these hot summer days.

The trio are trying to run the visionOS sample apps, but broken Xcode betas are getting in the way! Undeterred, Kotaro leads a discussion on what you can learn via the four visionOS demo apps (if you get them running). Then, the trio speculates about the forthcoming dev kits, Steve brings up the movie Hackers (because it's awesome!), and we end the show with some truly "bad app ideas." We are taking baby steps into our spacial computing developer journeys!

The trio have had some initial hands-on time with the visionOS SDK and are ready to dive into a new development adventure. That's right, it's time to pivot! We think visionOS is a rare opportunity that should not be missed by Apple developers. Maybe it's a big nothing burger, maybe it'll be a new App Store gold rush, maybe somewhere in between, but the time to start exploring this new platform is now! In this episode, we talk about what we have already learned from the visionOS SDK before discussing some very rough prototyping ideas we want to use to start exploring this brave new Spatial Computing world.

Twas the pod before WWDC and the trio decided to enjoy themselves with a little speculation about what gifts Apple will bestow on June 5, 2023. Most of the discussion centers on speculation about the "mythical goggles" rumored to be released along with a brief tangent on widgets, some thoughts on whether Apple will even utter the acronym, "AI," during the conference, and we end with a nerdy grab bag wishlist of features we hope to see added to Apple's platforms this year. Don't miss the Not a Sponsor segment this week as Steve demonstrates that the Clip Dish devs' prompt engineering is second to none!
