no option for "Extended Runtime Session"
How can I enable "Extended Runtime Sessions" for a companion watch app? Here https://developer.apple.com/documentation/watchkit/using-extended-runtime-sessions in targets under 'Signing & Capabilities' I checked "Audio" and Session Type 'Mindfulness', I created an ExtendedRuntimeManager.swift file. When running a simulation the error message says "Extended Runtime Session ungültig: Reason=-1, Error=This application does not have appropriate permissions to schedule a session." How does the app get the 'appropriate permissions'?

Unabled compiler
Hello the community, how are you? Since few days, this messages displays as an error into my code: "The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions" Since all these days, I'm not able to solve this problem. My app is almost done and the code is good. But I don't find where the problem is from. Here's the block where the message appears: var body: some View { //The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions VStack { TextField("Search invoices...", text: $searchText) .padding(10) .background(Color.gray.opacity(0.1)) .cornerRadius(10) .padding(.horizontal) HStack { ForEach(BillFilter.allCases) { filter in Button(action: { selectedFilter = filter }) { Text(filter.rawValue) .padding() .background(selectedFilter == filter ? Color.accentColor : Color.gray.opacity(0.2)) .foregroundColor(selectedFilter == filter ? .white : .black) .cornerRadius(8) } } All the best,

Submitting a Swift Playgrounds app
Certain documentation seems to suggest I can submit a swift playground to the App Store. I am a paid $99 a year developer. In the submission process they ask for my team ID. I am not part of a team. I am an individual. However, my individual account has a team ID associated with it, but they don’t allow me to enter that number in the space provided. There is an * note saying some teams are not permitted to upload to the Apple store connect. How do I, a paid up developer, submit a swift playgrounds app to the App Store?.

Does Swift Playground Support Custom Code Snippets Like Xcode?
While demonstrating Swift Playground to my students, I noticed that, unlike Xcode, it doesn’t seem possible to predefine or insert custom code snippets. In Xcode, we can easily create and reuse our own code snippets to improve teaching and development efficiency, but I couldn’t find a similar feature in Swift Playground. Is there currently a way to predefine or insert custom code snippets in Swift Playground? Are there any recommended workarounds, or plans to support this feature in the future? Any suggestions or insights would be greatly appreciated.

Suppress “Access Data from Other Apps” Popup in Swift Playgrounds Template on macOS 26
I’m using Swift Playgrounds on macOS 26 to learn app development, starting with the “Get Started with Apps” template. Every time I run the template, macOS shows a popup asking: “Get Started with Apps” wants to access data from other apps. Allow / Don’t Allow I’ve already tried: Granting Playgrounds Full Disk Access in System Settings → Privacy & Security Checking Automation / App Permissions Restarting Playgrounds and macOS …but the popup still appears every run. I’m aware this is related to App Sandbox and privacy restrictions, but I’m looking for a way to: Suppress this popup entirely while running playgrounds code, or Run the template in a way that avoids triggering this permission request. macOS version: 26.1 Playgrounds app version: 4.6.4

Foundation Models support in Swift Playgrounds | SSC26
Hello. I'm building my Swift Student Challenge Project. But I noticed that the FoundationModels Framework isn't supported in Swift Playgrounds. My app uses ARKit, so it definitely should be tested on real device. So, is it possible to somehow implement a foundation models to my Swift Playgrounds app? Or is it possible to ask judges to test the app on real device launching it from xcode. Your answer is really important for because the functionality of my app directly depends on Foundation Models availability. Thank you!

#Playgrounds conflict duplicate libraries
Experimenting with #Playground macro with Xcode 26 beta 3, out of the box I see a conflict between duplicates in the XcodeDefault Toolchain. Essentially a clean install of macOS Tahoe 26 25A5306g FB18930059 Was trying to follow the first Foundation Model WWDC video example but distilling it down to the most basic use of the Playground macro produces the same error. import Playgrounds #Playground { } Any solutions / workarounds? Wasn't sure whether to attempt to delete one of these–but they are internal libraries. objc[3241]: Class PGLConcurrentMapNode is implemented in both /Applications/Xcode-beta 3.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/Developer/Platforms/MacOSX.platform/Developer/Library/PrivateFrameworks/PlaygroundLogger.framework/Versions/A/PlaygroundLogger (0x10db98c10) and /Applications/Xcode-beta 3.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/macosx/libLiveExecutionResultsLogger.dylib (0x10db18050). This may cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed. error: Couldn't look up symbols: protocol descriptor for Playgrounds.__PlaygroundsContentRecordContainer```

Cannot Upload Images on Swift Playground on XCode
Hello! I'm trying to upload images to Swift Playground on XCode, and it's not working. When I created my playground, there is no Resources folder or an assets file. If I simply drag an image file to the sidebar, the image is not showing up when used in the app. This may be a simple fix, but as a beginner, I am struggling to find the solution. Any help would be much appreciated! Thank you!

In "Learning Programming 2", I can't use "world.place"
I'm trying the "Connect and Solve" course of Swift Playground. I can't use "world.place" to place bricks at positions (2, 2), (6, 2) (automatically disappear), but I can place bricks at positions (4, 2) in the same way. Two bricks must be placed overlapping in positions (2, 2) and (6, 2) to achieve the goal. Only when a brick is placed in position (4, 2) can the goal be achieved. The problem is that the bricks placed on (6, 2) and (2, 2) will disappear and cannot be placed successfully. The following is my code writing... let Block1 = Block() for i in 1 ... 2 { world.place(Block1, atColumn: 2, row: 2) } for i in 1 ... 2 { world.place(Block1, atColumn: 6, row: 2) } world.place(Block1, atColumn: 4, row: 2) func turnaround() { turnRight() turnRight() } func walk4() { for i in 1 ... 3 { moveForward() } } func collet() { for i in 1 ... 2 { moveForward() } toggleSwitch() turnRight() walk4() collectGem() turnaround() walk4() turnRight() } for i in 1 ... 3 { collet() } ‌I would appreciate it if someone could offer some recommendations.‌ ‌Thanks a lot‌
