GitHub - twostraws/Inferno: Metal shaders for SwiftUI. Metal shaders for SwiftUI. Contribute to twostraws/Inferno development by creating an account on GitHub.

One of the most fun parts for me building DJ Mood was using Metal shaders thanks to Inferno by @twostraws .

I am also making this post my public accountability statement to send Paul a PR to contribute my custom shader for others to reuse!

For us coders: I had never gone through the process of writing an app for the trio of iOS, macOS and tvOS before! Very illuminating as to how the user experience still needs to be customized for each platform. Even though SwiftUI gives us high reusability, it doesn't go nearly far enough to be a […]

Anyone in my socials enjoy visiting Disney theme parks? I'm working on an iPhone app that may appeal to Disney park fans and I'd love to find some folks to share an early beta with. If you would be interested, please message me back.

With Liquid Glass, I like what some developers chose to implement: completely distinct UI layouts for iPhone (closer to what Apple has done) from iPad, Mac, and tvOS, such as a NavigationSplitView for iPad and/or Mac versus TabView for iPhone and tvOS. This feels far more platform appropriate […]

Ok then…Iate to the party, but I decided to try to try some Liquid Glass tab bars with an accessory view and stuff, naively optimistic that it wouldn’t be as broken and weird as so many of y’all have said it is.

I stand corrected. I feel your frustration, folks. This is a day of coding I wish I […]

@vrhermit have you ever seen a way in RealityKit to add a highlight around an Entity, like when an Entity is selected in Reality Composer Pro? Put a little glow outline around it?

Ok, I'm truly torn. One the one hand, I'd love to try macOS Tahoe beta with Xcode 26 and try coding with some AI support to see how that goes. Should I:

* go all in, upgrade my laptop to Tahoe
* partition a volume and reboot into it to try this stuff out or
* fogetaboutit, it's not worth it […]

#til #wwdc the helpful answer I got from the Apple team about SwiftUI window management was to look at the new .defaultLaunchBehavior and .restorationBehavior view modifiers in visionOS 26. To help make window management more…manageable.

If you are concerned about the proposed 50% cut to #NASA's science budget, then write your representative in congress. The #PlanetarySociety provides on online form that will only take 2 minutes of your time:

Finally had the courage to try Swift 6 mode in a new app project I'm working on. Only 3 errors, now fixed, all app functionality maintained. Making my SwiftData models Codable required adding Sendable structs of my model classes.

@Drmarkpowell It's been having some perfomance issues due to some Bluesky stuff changing but https://skybridge.fly.dev lets you use Ivory with Bluesky. It's missing a few things but the tradeoff has been worth it to me.

I just tried hooking up #reederapp to my Bluesky and Mastodon accounts, and it is functional but hardly optimal. The scroll is not ideal for reading posts…it’s no #Ivory. But, they did get the idea that it sure is nice to have all the reading in one place.

Is there an app like #Ivory for BlueSky? I love Mastodon so much but I want to read what people are posting on BlueSky now as well, ideally with one app like Ivory. I set up the Bridgy Fed thing but I don't think it helps me do this…or I don't understand how to use it to help me do this.
