I went with this approach to the new TabBar which kinda got a bit inspired by Tidal. #iosdev #buildinpublic #swiftui #liquidglass #hatersgonnahate

SwiftUI’s List is only lazy when SwiftUI can determine how many views a ForEach element resolves to without evaluating the closure.

Two common patterns prevent this:

  • Using an if statement inside ForEach
  • Wrapping rows in AnyView

In both cases, SwiftUI evaluates the ForEach closure for every element before any rows are displayed.

You can learn more in the free sample chapter of my book “The SwiftUI Way”: https://books.nilcoalescing.com/the-swiftui-way/building-a-performant-and-stable-interface/maximizing-the-performance-of-dynamic-lists/

Any #iOS or #mac devs have a good resource for #SwiftUI #TDD? I think I'm OK on straight Swift testing. I'm specifically looking for reading up on SwiftUI testing.

Due to @MonaApp@mastodon.social never clearing the “iCloud Position Restored" button at the bottom of the app, I have inadvertently discovered a way to get decent shadows in modern macOS: just stack a dozen identical views on top of each other! #SwiftUI #LiquidGlass

I really wish there was a way to preview notifications during iOS app development without actually running the app and triggering a notification event. Like some Preview macro or debug framework that you can throw notification info to just to get a rendering of what it will look like. I really don't want to hide a button that actually creates a notification behind #IF DEBUG but it looks like that's what I'll have to do. #Swift #SwiftUI #iOS #Xcode

The #1 question my #SwiftUI students ask my TAs (and me) is how to fix "The Local Repository is Out of Date" error when trying to push from #Xcode to GitHub. I've created this YouTube video illustrating a fix. I hope it helps others. https://youtu.be/bEkuh95iajc

Hey #Swift #SwiftUI #iOS devs. How do you manage/increment your build numbers? I'm doing this on a solo project with no CI. Just me and Xcode on my personal machine.

Increasingly disappointed to learn you can't write a standalone #iOS app with updatable Live Activities. It REQUIRES a server for remote push notifications for updating, something I do not want to write or maintain. #Swift #SwiftUI

Someone make sense of what the different Weights, Flexibility, and Impact of SensorFeedback in #SwiftUI mean. Also, what values are supported on which devices?
