I have been working with visionOS 27's website environment features, and I have found when entering a website environment, leaving the website environment, waiting 10 seconds, and then trying to re-enter the website environment, the attempt fails. The thrown error reports: AbortError: Immersive request was superseded by another request Strangely, if I try to immediately re-enter the website environment, I succeed. I have to wait several seconds before trying to re-enter the environment to experience the failure. The workaround is to reload the page. Anyone know why this is occurring or how to avoid it? Anyone know a more graceful workaround than asking the user to reload the page? I have filed a feedback on this: FB23208345

In visionOS 26 (with Website Environments enabled), there was a two step action to enable the environment: click button on the left of the address bar (1 in image), then click "Open Website Environment" (2 in image). This example was shown again this year in Build next-generation experiences with visionOS 27. But I do no see this working in visionOS 27. Instead, I've needed to add a button for the user to open (and optionally close) the website environment. Is adding a button/control to the web page the new way to activate website environments?

Is the website environment feature available on this first visionOS 27 beta? I am having troubles converting a web page that used the visionOS 26 website environment approach to the new visionOS 27 approach. Before I keep working on it, I would like confirmation that the feature is working. Also, does Apple have any web pages featuring a website environment that I can inspect?

I am testing auto renewing subscriptions for a macOS program in Xcode with a local Storekit file. I have renewals set to occur every minute for testing. I quit the app, and watch renewals appear in the Debug transaction manager window. Each is marked unfinished. When I start the app, I call a function that is supposed to get unfinished transactions and finish them. In one of those "I swore it worked the other day", I am now finding it isn't working. The unfinished transaction remain marked as unfinished. func getUnfinished() async { for await verificationResult in Transaction.unfinished { guard case .verified(let transaction) = verificationResult else { continue } await transaction.finish() } } If I add an AppStore.sync() right before looping on Transaction.unfinished, it works (i.e., cleans up unfinished transactions), but I get an alert I have to click through. do { try await AppStore.sync() } catch { print("DEBUG UNFINISHED: AppStore.sync() failed: \(error)") } Any idea why Transaction.unfinished isn't fetching unfinished transactions for me (without the AppStore.sync)?

[EDIT: Please ignore. Will delete in a second] Transaction.currentEntitlements is returning the complete history of transactions on a subscription product. I have a program with an In-App Purchase for a monthly subscription. I am testing with a local StoreKit file in Xcode. I configured the StoreKit test file to update every minute. When the program starts, I retrieve the current transactions from StoreKit to see if there is an active subscription. for await verificationResult in Transaction.currentEntitlements { guard case .verified(let transaction) = verificationResult else { continue } // update status for subscriptions This morning's testing is showing transactions for all transactions, both current and past. The current subscription renewal is sent plus all the past renewals that have expired. I thought in my previous testing that only one transaction (i.e., the latest/current) was sent per Product ID. Is this (all subscription transactions) the expected behavior, or should I file a bug report? Example debug output from Transaction.currentEntitlements loop (top transaction is the current one, but past expired ones are provided too; "DEBUG CURRENT ----" separates individual transactions): DEBUG CURRENT: getCurrentEntitlements BEGIN DEBUG CURRENT ---- DEBUG CURRENT: for product pro.monthly DEBUG CURRENT: Verified Reason: Renewal DEBUG CURRENT: Ownership: Purchased DEBUG CURRENT: Purchases: is good DEBUG CURRENT: signed date: 2026-03-26 17:37:12 +0000 DEBUG CURRENT: purchase date: 2026-03-26 17:36:24 +0000 DEBUG CURRENT: environment: Environment(rawValue: "Xcode") DEBUG CURRENT: store front: Storefront(countryCode: "USA", id: "143441", localeStorage: en_US (fixed en_US)) DEBUG CURRENT ---- DEBUG CURRENT: for product pro.monthly DEBUG CURRENT: Verified Reason: Renewal DEBUG CURRENT: Ownership: Purchased DEBUG CURRENT: Expired 2026-03-26 17:36:24 +0000 DEBUG CURRENT: signed date: 2026-03-26 17:35:25 +0000 DEBUG CURRENT: purchase date: 2026-03-26 17:35:24 +0000 DEBUG CURRENT: environment: Environment(rawValue: "Xcode") DEBUG CURRENT: store front: Storefront(countryCode: "USA", id: "143441", localeStorage: en_US (fixed en_US)) DEBUG CURRENT ---- DEBUG CURRENT: for product pro.monthly DEBUG CURRENT: Verified Reason: Renewal DEBUG CURRENT: Ownership: Purchased DEBUG CURRENT: Expired 2026-03-26 17:35:24 +0000 DEBUG CURRENT: signed date: 2026-03-26 17:34:25 +0000 DEBUG CURRENT: purchase date: 2026-03-26 17:34:24 +0000 DEBUG CURRENT: environment: Environment(rawValue: "Xcode") DEBUG CURRENT: store front: Storefront(countryCode: "USA", id: "143441", localeStorage: en_US (fixed en_US))

After I updated to visionOS 26.4, I noticed my website environment would suddenly turn off occasionally while I was watching YouTube in Safari. My M2 AVP was still warm after the update. Is turning off a website environment expected behavior when the headset gets warm (e.g., perhaps to reduce load)? If not, anyone have an idea this might happen?

After updating to visionOS 26.4, I went to Safari's Feature Flags page to reenable Website environment, and I found the Website environment switch had been moved from the top and into the list of switches below. In its place is "Immersive API". I could not find any documentation on this. Anyone know what it is for or can point me to documentation?

Apple provides sample code for compressing a single file here, but the "aa" command and Finder cannot decompress these files. I needed to write a custom decompresser using Apple's sample code here. Apple provides sample code for creating an "aar" file for directories here and a single string here, and the aa command and Finder can deal with these. However, I have struggled creating an ".aar" file for a single file. The file could be quite large, so reading it into memory and writing it as a blob is not an option. Does anyone have suggestions or can point me to Apple documentation that can create a ".aar" file for a single file?

Apple's new Spatial Personas use Gaussian Splatting, but I have not found any APIs for visionOS to display a Gaussian Splat like a PLY file. Am I just missing the Apple documentation? If not, are there common practices developers are using for displaying Gaussian Splats in visionOS?

This is just an FYI in case someone else runs into this problem. This afternoon (12 Dec 2025), I updated to macOS 26.2 and lost my network. The System Settings' Wi-Fi light was green and said it was connected, but traceroute showed "No route to host". I turned Wi-Fi on & off. I rebooted the Mac. I rebooted the eero network. I switched to tethering to my iPhone. I switched to physical ethernet cable. Nothing worked. Then I remembered I had a beta of an app with a network system extension that was distributed through TestFlight. I deleted the app, and networking came right back. I had this same problem ~2 years ago. Same story: app with network system extension + TestFlight + macOS update = lost network. (My TestFlight build might have expired, but I'm not certain) I don't know if anyone else has had this problem, but I thought I'd share this in case it helps.

I am using WebView and WebPage to display web pages. Some web pages have content fixed to the top of the screen (like apple.com). When this happens, content is under the status bar (like menu buttons), and I cannot tap them. My work around is to put the WebView in a VStack with the top being Color.clear.frame(height: 44). It isn't very elegant, especially since it is applied to all pages and not just pages with fixed content at the top. Is there a more Apple-y way to solve this? For example, Safari seems to detect these situations and puts something like Color.clear.frame(height: 44) in those cases but not other cases. Here is sample code: import SwiftUI import WebKit struct ContentView: View { @State private var page: WebPage init() { let configuration = WebPage.Configuration() page = WebPage(configuration: configuration) let url = URL(string: "https://www.apple.com")! let request = URLRequest(url: url) page.load(request) } var body: some View { WebView(page) } } Here is a screenshot of Apple's page in WebView with the menu Here is a screenshot of Apple's page in Safari. It appears to have inserted a spacer frame at the top for Apple's page (but not, for example, my own web site which doesn't have this problem).

I have an iOS app that can display a USDZ model downloaded from the Internet (and cached locally) via an ARView. I would like to light that model with an image based light (IBL) also downloaded from the Internet. However, as far as I can tell, ARView can only create an IBL from a resource that has been compiled into the Xcode project and loaded with EnvironmentResource(named:in:) or EnvironmentResource.load(named:in:). Is there a way to create an EnvironmentResource from an HDRI via a file URL to use in ARView in iOS?

Apple's WWDC video What’s new for the spatial web says the spatial-backdrop markup may change as it goes through the standards process (at 27:26 mark). I have started adding spatial-backdrops to web pages, so I want to keep an eye out for status updates by Apple and follow the standards progress. Is there any place I can keep an eye on this standards process? Has Apple announced any feature updates or news on spatial-backdrops?

I have a visionOS app using Apple's WebView and WebPage to display web content. When viewing a live YouTube stream last night, YouTube put up the warning in the area that would have the chat window: Oh no! It looks like you're using an older version of your browser. Please update it to use live chat. Anyone know if YouTube is generating this from the server based on the WebPage's user agent string, from Javascript running in the browser engine, or something else? Anyone know if and how it is possible to resolve this? (See right side of YouTube web page from a screen grab):

In Reality Composer Pro, why is the Sky Sphere so much larger than the Sky Dome? By my estimate, the Sky Sphere has a radius of 100m, while the Sky only has a radius of only 12m.
