I was also really excited back in 2023 when Sima pitched the pack iteration feature as I was trying to build the AnimatablePack feature in ShapeUp and it was exactly what I needed to get it done.

Swift Forums · [Pitch] Enable pack iterationHello everyone! Parameter packs are an exciting new feature in Swift, but they quickly become very unintuitive when it comes to trying to express list operations on them. Currently, repetition patterns with packs are limited to expressions. This does not allow for short-circuiting with break or continue statements, so the pattern expression will always be evaluated once for every element in the pack. The only way to stop evaluation would be to mark the function/closure containing the pattern e...

Made a lot more progress today decoding invoices and setting up everything on the backend. Tomorrow, let's add the final pieces for trials, then integrate with the frontend, and start testing. See you then!

@bwebster I would think that explicitly specifying a timeZone on the FormatStyle should override the environment (as it apparently did), so I'm pretty sure this is an actual #SwiftUI bug.
However, I wouldn't manually do that, but rather adjust the locale or timezone environment anyways. mastodon.social/@helge/1139135

```swift struct ContentView: View { var body: some View { VStack { let now = Date() Group { Text("\(now, format: Date.FormatStyle(date: .abbreviated))") Text("\(now.formatted(date: .abbreviated, time: .omitted))") } .environment(\.locale, Locale(identifier: "de_DE")) Divider() Group { Text("\(now, format: Date.FormatStyle(date: .abbreviated))") Text("\(now.formatted(date: .abbreviated, time: .omitted))") } .environment(\.locale, Locale(identifier: "en_US")) } } } ```
MastodonHelge Heß (@helge@mastodon.social)Attached: 2 images In #SwiftUI people sometimes format values, say dates or numbers, by directly calling `.formatted()` on them, which results in a `String`. It is actually better to use `Text`’s interpolations to do that, because that takes the locale of the environment into account (vs. .formatted, which uses the "global" default locale). Notice how the second `Text` in each group sticks to the German date style I have set in the system.

So apparently trying to use SwiftUI's Text element with a Date.FormatStyle that uses a time zone is broken on macOS 15 and iOS 18. 🤦‍♂️

Here's the same code running on iOS 18 and iOS 17. Am I missing something here or is this just plain broken? #SwiftUI

SwiftUI code showing three Text elements showing the same date with no time zone, the current time zone, and GMT.
Side by side iOS simulators. iOS 18 shows all three dates the same, iOS 17 shows a different time for the GMT time zone.

Hopefully it’s a case of me just being paranoid. The non-deprecated tab declaration does appear to use more memory but it just seems to hit a ceiling sooner. The memory graph items just decided not to show up any more so I'm hoping it's not a real issue.

Doing a more serious analysis with excessive data seems to shows it performs in a good range. I'll sit on this build and focus on getting my custom link preview code pulled out for a public repo too.

Moving my TabView tab's to the non-deprecated declaration seems to result in memory that never goes back down. It doesn't grow by loads but so far it appears to only trend upwards and I've ended up with new leaked items in the memory graph.

This is an annoying part of #SwiftUI. Maybe something I've done has caused this but then again maybe not.The leaked items are for keyboard state by the looks of it

I'd like to avoid deprecated code but maybe I'll wait.

Cleaned up the model, updated deletion to take care of stripe data, added more logging, and even started processing checkout sessions! Tomorrow let’s create transactions for invoices and prep to test the whole flow. See you then!
