Swift 6

Hi, Are there rules around using Foundation Models: In a background task/session? Concurrently, i.e. a bunch simultaneously using Swift Concurrency? I couldn't find this in the docs (sorry if I missed it) so wondering what's supported and what the best practice is here. In case it matters, my primary platform is Vision Pro (so, M2).

Hi everyone, I’ve run into a strange issue while building my app with Xcode 26 beta 6 (targeting iOS 26). When I include an app icon created using Icon Composer, the build time jumps to over 5 minutes. During this time, I noticed that a utility called AssetCatalogSimulatorAgent is consuming a significant amount of CPU. If I remove the Icon Composer-generated icon from my target, the build completes in about 40 seconds. This behavior is consistent across multiple builds. Has anyone else experienced this? Is there a known workaround or optimization for icons created with Icon Composer? I’d love to keep using the new icon format, but the build time is becoming a real bottleneck. Thanks in advance!

Hello, While watching WWDC25: Code-along: Elevate an app with Swift concurrency at timestamp 25:48, I noticed something in the slide/diagram that might be incorrect. The diagram shows ExtractSticker twice, but based on the code context and spoken explanation, I think it was meant to be ExtractSticker and ExtractColor. Reasoning: The surrounding code and narration describe the use of async let and a Sendable Data object. From the flow, one task extracts a sticker while the other extracts a color, so it seems like the diagram is inconsistent. I do understand that with @concurrent, having two ExtractSticker operations on the same Data is technically possible (with two concurrent process executing their respective ExtractSticker) — but that would be a different meaning than what the talk was describing. Since concurrency is already a subtle and error-prone topic, I thought it was worth pointing this out. If I’m mistaken, I’d love clarification. Otherwise, this could be a small correction to keep things a

I’m new to iOS development. Previously, I’ve worked with Python and Django, mainly using JetBrains PyCharm PRO. In PyCharm, I really benefit from plugins like Rainbow Brackets , which help a lot with readability and code navigation. As someone who wears glasses, I find such visual aids very helpful for reducing eye strain. While exploring Xcode, I noticed that similar built-in features or up-to-date plugin support seem limited. Considering Apple’s strong focus on accessibility and user experience, I was a bit surprised by this. With Xcode 26 coming soon, I’m also wondering if there will be improvements in plugin support or built-in tools like Swift Linter and Swift Format. Are there any current tools or plugins you’d recommend to fill these gaps?

It's related to the passByValue nature of structs. In the sample code below, I'm displaying a list of structs (and I can add instances to my list using Int.random(1..<3) to pick one of two possible predefined versions of the struct). I also have a detail view that can modify the details of a single struct. However when I run this code, it will instead modify all the instances (ie either Sunday or Monday) in my list. To see this behaviour, run the following code and: tap New Trigger enough times that there are multiple of at least one of the sunday/monday triggers tap one of the matching trigger rows modify either the day, or the int expected: only one of the rows will reflect the edit actual: all the matching instances will be updated. This suggests to me that my Sunday and Monday static instances are being passed by reference when they get added to the array. But I had thought structs were strictly pass by value. What am I missing? thanks in advance for any wisdom, Mike struct ContentView: View { @State v
