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?

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?

[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))

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)?
