I am wanting to create a 3D video game in Xcode for macOS, iOS, iPadOS, tvOS, and visionOS. I have heard that there are a few different ways to go about this such as MetalKit or SceneKit. These libraries seem to have little examples and documentation so I am wondering:
Are they still be developed/supported?
Which platform should I make a game in?
Where are some resources to learn how to use these platforms?
Are there other better platforms that I am just not aware of?
Thanks!

Hello. I've been looking all over this forum and stack and done some internet searches but unfortunately have found nothing to assist in fixing an error I'm receiving on my project in Xcode.
Every view shows an error identical to the one shown above, only with that specific file name displayed instead. When I go to fix the error, this is the error detail displayed:
== PREVIEW UPDATE ERROR:
LinkDylibError: Failed to build TabBar.swift
Linking failed: linker command failed with exit code 1 (use -v to see invocation)
ld: warning: search path '/Applications/Xcode.app/Contents/SharedFrameworks-iphonesimulator' not found
ld: unsupported mach-o filetype (only MH_OBJECT and MH_DYLIB can be linked) in '/Users/brycemchose/Library/Developer/Xcode/DerivedData/Service_Square_App-dnblqgabcrxprhaizjtkcvouyzln/Build/Intermediates.noindex/Previews/iphonesimulator/Service Square App/Products/Debug-iphonesimulator/Service Square.app/Service Square'
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Note that I can run the app successfully to a simulator or to my iPhone, but cannot see the preview within the Xcode canvas. I've been blindly developing the last two app updates, pushing the changes to the simulator and then tweaking the code based on the simulated version. I can keep doing this for a little while but it is significantly slower and more difficult, especially to fix small bugs and make tiny changes, so I'd really like to see if anyone has an idea for how I can get the preview back to being properly displayed. I'm brand new to this whole thing and have no idea how to fix this issue, so I'd be really grateful if someone with more experience could offer some suggestions! Thanks in advance! :)

Hi everyone
I'm new to swiftui and I'm trying to understand the reason that allows swiftui to call a VStack or any other container view without parentheses as in:
struct ContentView: View {
var body: some View {
VStack {
Text("sth");
}
}
}
After looking into the swift docs, it was clear as in any other programming language that instantiating a class/structure is made by calling the entity with its parentheses, an even passing some parameters if possible.
Isn't should be the case for placing view components in the body computer property?
So far my mind keeps telling me that the syntax should follow this convention
struct ContentView: View {
var body: some View {
VStack() {
Text("sth");
}
}
}
At which concept should I look into for further clarifications
All the best.

Privacy and Security Settings on Apple Watch requires a screen time passcode, but when I enter the correct passcode, it says its wrong. I need to get into these settings to access developer mode on my watch. If you know how to fix this, please help.

I'm writing a SpriteKit game in Swift that does this familiar dance in my GameScene touchesEnded(...)...
let touch = touches.first!.location(in: self)
let nodes = self.nodes(at: touch)
...but sometimes when the game is running, the nodes collection is empty, even though there are clearly, visibly nodes under the touch. All of the nodes I care about are children of a single SKNode, MapNode, that is one of two children of the GameScene.
After a bunch of debugging, I've noticed that when this problem happens, something is causing calculateAccumulatedFrame() to return a frame that is way, way smaller than the real bounds of MapNode.
When the scene begins, calculateAccumulatedFrame() is perfect, but something that happens later on breaks it. I've tried adding a node to MapNode that is the correct size to 'force' calculateAccumulatedFrame to do the right thing, but this doesn't work.
Is there something obvious I am doing wrong, or some common pitfalls? Is there some way to force calculateAccumulatedFrame to return this correct size?

I added debug break point to the first line of MyDeviceActivityMonitor.swift, it never got trigger.
I am able to launch the app, select discouraged and encouraged app.
discouraged apps are getting restricted which is expected. but device activity extension is never called.
I have all the permission and certificate. I created an app group.

I already filed feedback FB13777941 for this, but wanted to ask if anyone has the same problem, since I can't find anything on google or SO.
I created a new package in Xcode (15.3) and added this to it:
import SwiftUI
struct Test: View {
var body: some View {
Text("Hello world")
}
}
#Preview {
Test()
}
The package builds, tests can run. Previews don't work.
This is more or less the error I get from the diagnostics button (formatted for readability):

I don't remember ever having this problem. The arm64 vs arm64e makes no sense to me - why would Xcode get that wrong... and only for previews?
I've tried restarting, deleting derived data, the usual rain dances.
Any ideas?

Dear all,
I have the following two classes:
Stagioni:
import SwiftData
@Model
class Stagione {
@Attribute(.unique) var idStagione: String
var categoriaStagione: String
var miaSquadra: String
@Relationship(deleteRule: .cascade) var rosa: [Rosa]?
@Relationship(deleteRule: .cascade) var squadra: [Squadre]?
@Relationship(deleteRule: .cascade) var partita: [CalendarioPartite]?
init(idStagione: String, categoriaStagione: String, miaSquadra: String) {
self.idStagione = idStagione
self.categoriaStagione = categoriaStagione
self.miaSquadra = miaSquadra
}
}
CalendarioPartite:
import SwiftData
@Model
class CalendarioPartite {
var idGiornata: Int
var dataPartita: Date
var squadraCasa: String
var squadraTrasferta: String
var golCasa: Int
var golTrasferta: Int
var stagione: Stagione?
init(idGiornata: Int, dataPartita: Date, squadraCasa: String, squadraTrasferta: String, golCasa: Int, golTrasferta: Int) {
self.idGiornata = idGiornata
self.dataPartita = dataPartita
self.squadraCasa = squadraCasa
self.squadraTrasferta = squadraTrasferta
self.golCasa = golCasa
self.golTrasferta = golTrasferta
}
}
Now, I'd like to have a query which is showing in a view the list of partite depending on a selection of a specific Stagione.
I've tried with the following query, but I'm getting the following error: "Instance member 'selectedStagione' cannot be used on type 'CalendarioCampionatoView'; did you mean to use a value of this type instead?"
@Query(filter: #Predicate<CalendarioPartite> { $0.stagione == selectedStagione}) private var partite: [CalendarioPartite] = []
What I'm doing wrong?
Thanks,
A.

I am guessing this is a NavigationSplitView and the menu is in the sidebar closure. But I'm not quite sure how to reproduce this style of menu. Along with the collapsing breadcrumb for back button. I would have thought this would be out of the box?

There seems to be a long running issue with WidgetKit where some users don't see the widget when trying to add to their Home Screen. (even after opening the app for the first time).
I have been able to reproduce myself intermittently, and typically restarting the phone or re-installing the app fixes the problem. However, some of my users have encountered this and end up requesting refunds because they think the app is broken.
Has anybody else experienced this issue?
Would be great to get this bug resolved as it's frustrating for users.

We need additional time to evaluate your submission and Apple Developer Program account. Your submission status will appear as "Rejected" in App Store Connect while we investigate. However, we do not require a revised binary or additional information from you at this time.

Xcode version: 15.2, iOS deployment target 15.0
When experimenting with the new Xcode 15/new linker feature "Mergable Libraries" I came across an issue with subproject framework products.
I have a workspace with two projects.
I want to create a group framework named GroupFramework that consists of three other frameworks. FrameworkA, FrameworkB and FrameworkC.
FrameworkA and FrameworkB are in the same project as the group framework I want to create. FrameworkC is a product of another project in my workspace.
GroupFramework has all three frameworks linked in the "link binary with libraries" build phase.
GroupFramework has "Create merged binary" set to manual because I want to control which frameworks are linked. FrameworkA, FrameworkB and FrameworkC all have "Build mergeabe library" set to YES.
The application builds in both RELEASE and DEBUG.
Running in DEBUG and RELEASE
When running the application on a device in DEBUG or RELEASE it crashes with a linker error because FrameworkC can't be found on disk.
When inspecting the app binary in RELEASE I can see that FrameworkA and FrameworkB are both in the ReexportedBinary folder, but FrameworkC is nowhere to be seen.
I have tried embedding FrameworkC explicitly in the settings of the GroupFramework essentially creating an umbrella framework, and that also does not fix the issue.
I have also tried embedding FrameworkC directly into the AppTarget that will consume GroupFramework. This solves the linking issue but a new issue regarding unresolved symbols then crops up.
It appears as though the Reexporting and Merging of subproject frameworks is not working compared to a product that exists in the same project or at least may require a lot more manual configuration which is not currently documented anywhere. If this is the case, it could be very problematic when trying to adopt mergeable libraries in multi-project workspaces.

I have spent hours trying to get @Query macros to compile. Mostly they throw up meaningless errors for example the following produces 3 compiler errors:
@Query var stylesheets: [StyleSheet]
Here's the expansion.
The compiler complains that 'private' can't be used here, and it can't find _stylesheets. I searched everywhere to find a resolution then I came across the Query struct. I used it as follows to replace the @Query:
let query = Query(FetchDescriptor<StyleSheet>(), animation: .smooth)
let styleSheets = query.wrappedValue
This also solves another issue that was bugging me - how to get the context when the environment variable is often rejected. All I need to do now is write:
let context = query.modelContext
None of the WWDC23 SwiftData videos mentions the use of the struct, which is a shame. It feels much like the CoreData approach to fetching data.
I hope this helps some of you.

Can someone update about the current state of the Automator app in macOS. Automator seems like a valuable tool for automating tasks on macOS but in the recent years I have noticed a growing emphasis on the Shortcuts app for automation.
It would be great if you could clarify the following:
• Current Status of Automator: Is there any official statement regarding the continued support of the Automator app in future macOS versions?
• Future of Automator: Does Apple plan to introduce new features or updates for Automator in upcoming releases?
• Indifference to Shortcuts App: From what I understand both the ‘Automator’ and the ‘Shortcuts’ app are used for creating workflows/shortcuts to automate tasks. What is it that Automator app has to offer which cannot be done using the Shortcuts app? assuming the continued support for the Automator app. Can all the automator workflows not be automated using the shortcuts app?
I understand that Apple is constantly innovating and introducing new tools. However, clarity regarding the future of Automator would be helpful for users like myself.
In addition, as a developer I wanted to offer some actions for my application in the Automator app, so that the user can make use of it to create some workflows. But from what I found in the apple documentation here, these action are created using the ‘Automator action’ Project type template in the xcode. However, in the current version of xcode 15, this project type seems to be missing. Does it indicate that apple no longer provides support for applications to create new automator action? If not, how can I provide automator actions for my xcode application?

How are Strongbox able to do this with their afproxy executable?

Hi People :)
I'm experimenting with Swift/C++ interoperability these days.
I'd like to understand how could I conform a Swift class to Cxx header:
Like this:
import Application
class App: Application {
public func run() {
let app = NSApplication.shared
let delegate = AppDelegate()
app.delegate = delegate
app.run()
}
}
But I got this error:
/Users/tonygo/oss/native-research/App.swift:27:7: error: inheritance from non-protocol, non-class type 'Application'
class App: Application {
^
ninja: build stopped: subcommand failed.
That seems normal indeed.
Reproductible example: https://github.com/tony-go/native-research/tree/conform-swift-to-cxx-header (Just run make)
I also have another branch on that repo where I use an intermediate Cxx bridge file that conforms to the :Application class and use the Swift API, like this: https://github.com/tony-go/native-research/tree/main/app
Bit I think that its a lot of boilerplate.
So I wonder which approach could I take for this?
Cheers :)
