This is the time post-WWDC where I try to get all my projects building to a shippable state again with the new Xcode after working on experimental tangents and rabbit holes for months 😅 I think everything in my dev version of @pastelapp works again now, but I can't remember what I broke.
I'm doing a pass at a bunch of little things, shuffling some bits around, updating iconography etc
An awful lot of bringup for an existing iOS view controller on visionOS involves three things:
• Change your background color
• Round out your shapes/set your button configurations to the system rounded style
• Add roundrect hover styles
Here's a before/after on my wallpaper generator; just a handful of one-line changes
I built this palette-generation feature two years ago for @pastelapp, hoping that Apple would ship LLM APIs I could use instead of GPT-3. Womp womp.
Here's hoping tomorrow brings some change here…
Finally trying Apple's Foundation Models for palette generation, side by side with what I generated with ChatGPT.
The first image is the prompt "Planets of the Solar System" with Apple's on-device LLM, the second image is the same prompt using GPT-3.5 as of 2 years ago.
It can certainly do what I need it to do; whether the results are any good is an open question. I think it's inoffensive, and harmless, at the very least, so maybe I can move forward with it
Enabling streaming, you can see that the Foundation Models API is slow — I would say alarmingly slow — on M1 hardware. I'm not even sure what kind of optimization I might be able to do to speed this up, as it's seemingly purely on the token generation side 🤔
It's going to take more than a little care and attention before you start sprinkling this all over your apps, that's for sure. Good to know
Still a long way to go, but here's a before/after on Pastel on macOS 26 as of the current build.
During development, you spend so much time looking at the new design that you kinda forget how it used to look
With today's work out of the way, I think Pastel's iOS 26 update is done for Mac and for iPhone. The iPad build is blocked by my earlier radar, and I haven't figured out a mitigation strategy yet, but we're nearly there
I've started the TestFlight process for Pastel for iOS and macOS 26. There are some known issues on iOS, including a severe hang, but most things are in place now, and there are still slots available 😄
This *is* a nice API!
The next minor version of @pastelapp will support exporting color palettes to Pixelmator Pro (on the Mac, at least, as they don't support that on iOS)
Update: now available!
Venturing out into the Great Unknown, I have finally made the switch from single-purchase to subscriptions in @pastelapp, for new customers, after talking about it for years.
I should have done it years ago, but the risk of the floor falling out from under me scared me off. Better late than never!
I'm much better prepared to handle the initial financial shock today, and as I've migrated everything to StoreKit 2 I've been really impressed by how easy Apple has made it to implement subscriptions
Why subscriptions? A one-time purchase revenue graph, even for a moderately successful app, looks like this. Yet work required only increases in complexity — Pastel has had 40 multiplatform updates since it launched in 2020, including two system UI redesigns, and a whole new OS (visionOS).
One-time purchases just aren't sustainable, unless the product itself is also one-and-done — and that's just not possible on a moving target like Apple's OSes. Revenue can't be inversely proportional to time
I've tried to make Pastel's subscription pricing as unobtrusive as possible. As it stands:
• Existing paid users are grandfathered in and don't have to subscribe
• New users can subscribe for $2/mo or $10/year, with two-week free trials
• If you are on an OS version that I know won't be supported going forward (though I haven't decided to drop support yet), you won't see subscription options at all, only the legacy one-time purchase (now $20)
TL;DR, if you already own the app, you won't notice
