Overview I have a navigation split view. The detail view contains a model now this model depends on id from the parent view. Questions How can I pass data from the parent view and yet create the view in the detail view? Or should I be pass the model from the parent view, but the problem is the parent view needs to persist model. Or is there a better approach?

Overview When calling onChange(of:initial:_:) with initial as true, closure called even when the value assigned is the same as previous value (not just the first time, subsequently too). However when initial value is false it is called only when value changes. Questions Is this a bug? Am I missing something?

Hi, For the questions the original posts they need to be notified by default. Presently unless the user taps on Opt in they wouldn't be notified. Having good default behavior is a big part of good design / usability. If user posts something then there is reason to believe that that the person would like to be informed when there is response to that thread. If the user wants to opt out that could be made as a button, usually a person would want to opt out only much later when the original poster has got response and doesn't want any more. Confusion There is an opt in banner on top of the thread and there is a bell icon below the post, not sure what the difference is. The banner is barely visible on dark mode as that is also black The whole experience causes confusion and lacks confidence whether the user will be notified or not. Forum participation Generally user participation in the forum is low. So by making opt in for the posts the user has posted that makes the participation even lesser even when the original poster wants to participate. Proposal By default any post the user posts, the bell icon would be pressed (turned on) for that post, meaning the poster will get notified If the user wants to opt out of the thread the user can press the bell icon to turn off notification for that thread. For all the posts that the user hasn't posted by default the user is turned off Please provide an option for users to turn on / off notifications on specific topics / tags, this can be helpful when some developer / Apple engineer wants to actively participate / follow a specific topic. Remove the banner on top seems and stick only to the bell icon.

Overview On Xcode 27, when trying to run on a specific destination, the option to “Clear Recent” is missing. This was available in Xcode 26. Manage Devices option exists, but this is to permanently add / remove destinations, this is different from “Clear Recent”. Please bring back “Clear Recent” (from Xcode 26 to Xcode 27) option to Xcode as it is very useful Environment: macOS 26.5.1 (25F80) Xcode 27.0 beta (27A5194q) Feedback FB23055381

Overview I have a view B contains @Query for cars, now this @Query predicate depends on an input which is passed from view A. Current approach I am creating @Query in the init of view B by using _cars. Questions Now how can I compose @Query based on input from view A? Is my approach correct? In my approach Query will be created every time init gets called Or is there a better approach?

Hi, The fonts / font sizes used in the developer forum seem so odd. Especially with markdown they don't fit well, it might seem Headings need to be more bold, they are thin now Please have a look at https://forums.swift.org, the formatting there is really nice Heading 1 (too thin needs to be more bold) I know these are little things but they all add up.

Overview When a project contains SwiftData and the Preview uses a in memory database, SwiftUI preview doesn't show the data Have a look at the ContentView preview Environment Xcode 27.0 beta (27A5194q) 26.5.1 (25F80) Feedback FB23041713 Please can you have a look at the feedback, it also has a sample project and screenshot

Hi, Platforms state of the union shows the following code: defer { await? log.close } Note: I understand await but await? seems new. Questions Is await? (question mark seems new) a new concept? What does it mean? Or is the question mark a typo?

Hi, Xcode 27 markdown rendering look fantastic, a big thanks to everyone who contributed to it. Truly such a delight seeing rendered beautifully!! I didn't see it explained in any of the Xcode sessions, if there are WWDC sessions or documentation on this please let me know. Questions Tables get rendered really well, how can I add or remove columns in a table? For links I noticed that I needed to add the link first and then title for the link later, or are there alternate ways?

Hi, On Xcode 27, whenever I create a new Project and select App, an untitled project is created. What is good: When I go on to save the project, the project name uses it to update target name which is nice. Problem: Every time it uses a placeholder team ID, I have to go and manually update the bundle ID and team. This could also lead to unnecessary provisioning profiles created with placeholder IDs. Proposal FB23033844 Xcode to use the last used Bundle ID and Team. This will be similar to how things were in Xcode 26

Hi, On Xcode 27, Device Hub, how to view the simulator with Point Accurate and Pixel Accurate window sizes? These are existing options on Xcode 26 Simulator, so would be nice to have them in Xcode 27 Device Hub. This would be needed sometimes to quickly measure things using a on screen ruler. Feedback FB23033231 If there is no option currently can you please provide options to provide to view Point Accurate and Pixel Accurate window sizes

Hi, I am planning to show the StoreKitError as alerts, I have corresponding custom Error so that I can show meaningful error messages. Reason I wanted to display error alert messages that describe the underlying error so that when in production and user faces this error I would be able to reason about the error and try to resolve the error in a app update or Appstore Connect change. If I display a generic error I wouldn't know the cause of the error, but is there is a security risk in display the following kind of messages? Proposed UI error messages: | Error | UI alert message | | ------------------------------------ | ----------------------------------------------- | | StoreKitError.notEntitled | App is not entitled to make this request. | | PurchaseError.invalidOfferSignature | Invalid offer signature. | Questions From a security / user perspective is it risky / wrong to show an error message like the ones pasted above? Or are there some errors I shouldn't explicitly state? Or is there a better / preferred approach?

Hi, Overview I would like to add a Swift Package to my Xcode project. Problem In Xcode when I select Project > Package Dependencies and Press + button to add a dependency it keeps spinning and doesn't end Points to note: Xcode 26.5 (17F42) macOS 26.5 (25F71) This is a private GitHub repository I am able to clone the Swift Package URL on the command line. Xcode has the GitHub account I am able to push and pull code on that GitHub account using Xcode My failed attempt rm -rf ~/Library/Developer/Xcode/DerivedData rm -rf ~/Library/Caches/org.swift.swiftpm plutil -remove IDESwiftPackageAdditionAssistantRecentlyUsedPackages ~/Library/Preferences/com.apple.dt.Xcode.plist I have removed GitHub account in Xcode and added it again I am confused if I am missing something very obvious, any help on this is much appreciated. Questions Is there any workaround or way to fix this issue? Why does this take such a long time when I have a specific URL, either it needs to add it or return that the package is not found. Why is it searching?

Hi, Overview I have a SwiftData project which automatically syncs with CloudKit. When I run the app, I see the following error in Xcode logs. Error updating background task request: Error Domain=BGSystemTaskSchedulerErrorDomain Code=3 "(null)" My attempt I can enable Background processing (under Signing & Capabilities > Background modes), but I don't know the BGTaskSchedulerPermittedIdentifiers to add in the Info.plist Questions How can I resolve this?

Hi, Overview: I get the following error when trying to save / read from SwiftData It happens when I try to save color to SwiftData (code below) Error 'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release Questions How can I resolve the error? I am not directly using data, I am using just Float values, swift types. Why am I getting this error? Is there a way to add a breakpoint to stop at the exact type causing the error? (Symbolic breakpoint doesn't seem to help) Or is the below code ok and not responsible for the error? Code import SwiftUI nonisolated struct ColorRepresentation: Codable { let red: Float let green: Float let blue: Float let opacity: Float init(colorResolved: Color.Resolved) { red = colorResolved.red green = colorResolved.green blue = colorResolved.blue opacity = colorResolved.opacity } func color() throws -> Color { Color( red: Double(red), green: Double(green), blue: Double(blue), opacity: Double(opacity) ) } } extension ColorRepresentation: Equatable {}
