I am using SwiftData for my model. Until Xcode 15 beta 4 I did not have issues. Since beta 5 I am receiving the following red warning multiple times: 'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release This seems to be a CoreData warning. However, I am not using CoreData directly. I have no way to change the config of CoreData as used by SwiftData. My model just uses UUID, Int, String, Double, some of them as optionals or Arrays. I only use one attribute (.unique).

I've recently installed 26.1 Beta 3 alongside stable 26.0.1 When building my app with 26.0.1 the final .ipa size is ~17mb, however after building my app with 26.1 Beta 3 the size has increased up to ~22mb The main difference is Assets.car blowing from 1.1mb to 5.6mb (or 8.6mb if I include all icons settings). Upon examining I've found new liquid glass .icon file duplicating itself multiple times as png variants (any, dark, tinted, etc). Is anyone else experiencing this issue?

This example application crashes when entering any text to the token field with FAULT: NSGenericException: The window has been marked as needing another Update Constraints in Window pass, but it has already had more Update Constraints in Window passes than there are views in the window. The app uses controlTextDidChange to update a live preview where it accesses the objectValue of the token field. If one character is entered, it also looks like the NSTokenFieldDelegate methods tokenField(_:styleForRepresentedObject:) tokenField(_:editingStringForRepresentedObject:) tokenField(_:representedObjectForEditing:) are called more than 10000 times until the example app crashes on macOS Tahoe 26 beta 6. I've reported this issue with beta 1 as FB18088608, but haven't heard back so far. I have multiple occurrences of this issue in my app, which is working fine on previous versions of macOS. I haven't found a workaround yet, and I’m getting anxious of this issue persisting into the official release.

It seems that beta 3 broke StoreKit Testing when running against an iOS 26 simulator device. Specifically, when validating product IDs, the debug console displays messages like the following: [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) [492a4cfa_SK1] Could not parse product: missingValue(for: [StoreKit.ProductResponse.Key.price], expected: StoreKit.BackingValue) In addition, the SKProductsResponse (I am using the original StoreKit API), lists all requested product IDs in invalidProductIdentifiers. The products array is empty. StoreKit Testing behaves as expected when Xcode 26 beta 3 is run against an iOS 18.4 simulator device.

I've been running into lots of issues since I upgraded to 26.5 beta, spotlight doesn't work, mail index was broken and after deleting it I can't reindex my mail., after a while I get an error that reindexing failed and that I should relaunch that app and it will start over. It never succeeds Looking into the console, it seems that at least the mail issue, but also others system logging errors (trustd, coreduetd) are linked to corrupted sqlite databases. So I guess the sqlite version is a dud ?

I’m looking for a small number of iPhone users to test an app I’ve been building and give honest feedback on the UX. The app is called Triovel. It’s for a problem I kept running into after trips: photos end up in camera roll, plans are buried in chat, and later it’s surprisingly hard to reconstruct what actually happened on each day. The core idea is simple: rebuild or record a trip into a timeline of activities, then attach photos/notes to the right parts of the trip so everything stays together. At this stage, I’m not looking for generic “nice app” feedback. What I need most is feedback on: first-time onboarding clarity whether rebuilding a past trip feels intuitive where the flow feels slow, confusing, or unnecessary whether the timeline structure makes sense right away Good fit if you: recently came back from a trip have an upcoming trip or have old travel photos you never properly organized iPhone only for now. Early beta, so I expect rough edges. If anyone is open to trying it through TestFlight and giving blunt feedback, I’d really appreciate it. TestFlight: https://testflight.apple.com/join/6FJp6AMG

I have an issue where I’m pushing out my builds to TestFlight, it goes through. sometimes there’s an error saying that it can’t download but if I try a couple times it goes through. but when I go through and look at my app (That TestFlight says is running the updated version) all I see is the old version

I managed to install watchOS 2 without having registered my Watch's UDID, but as it's part of the instructions for installing watchOS betas I thought I'd better do it now in case beta 2 bricks my Watch or something.However, the Watch isn't appearing in Xcode. I've tried both the latest public release and Xcode 7 beta, but there's "no paired devices" section under my iPhone when I connect it to Xcode and look in the Devices window.

hi so i own a iphone 14 pro max and my battery life on it has been horrible since ios 26.4 and i want to install the public beta to see if it will fix it, however with my previous experiences from apple phones (iphone 4s) sometimes something can go horribly wrong and the baseband chip fries itself to the point where you cant get past recovery mode and get a restore error, im scared that this can happen to my iphone 14 pro max when installing ios beta. can that happen or am i just overthinking?

I just installed Xcode 26.4 RC (17E192) yesterday and found that the documentation window now omits Foundation for me. Searching for "Date" finds the date property from GameKit, Core Data, ... but no Date type. I was previously using 26.4 beta and this was not the case. Is anyone else seeing the same thing?

Hi all my apologies for being a little inexperienced. how do I install Tahoe 26.5 on an external SSD? I have downloaded the .IPSW but it won't instal. Dev

When using a ScrollView inside some sort of navigation (stack or split view), large navigation titles seem to get clipped to the width of the scroll content for some reason? Minimal example: struct ContentView: View { var body: some View { NavigationStack { ScrollView { Text("Scroll Content") } .navigationTitle("Navigation Title") } } } Results in: Is this a bug in the beta, or has something changed and now I’m doing things wrong?

We submitted our test flight build Thursday night, it's been over 60 hours. Does anyone have any suggestions on how to expedite this? I contacted support by going through Distribution -> TestFlight although it might be seen as a generic testflight question. The expedited app review route seems like it's only for AppStore.

We’ve encountered what appears to be a CoreML regression between macOS 26.0.1 and macOS 26.1 Beta. In macOS 26.0.1, CoreML models run and produce correct results. However, in macOS 26.1 Beta, the same models produce scrambled or corrupted outputs, suggesting that tensor memory is being read or written incorrectly. The behavior is consistent with a low-level stride or pointer arithmetic issue — for example, using 16-bit strides on 32-bit data or other mismatches in tensor layout handling. Reproduction Install ON1 Photo RAW 2026 or ON1 Resize 2026 on macOS 26.0.1. Use the newest Highest Quality resize model, which is Stable Diffusion–based and runs through CoreML. Observe correct, high-quality results. Upgrade to macOS 26.1 Beta and run the same operation again. The output becomes visually scrambled or corrupted. We are also seeing similar issues with another Stable Diffusion UNet model that previously worked correctly on macOS 26.0.1. This suggests the regression may affect multiple diffusion-style architectures, likely due to a change in CoreML’s tensor stride, layout computation, or memory alignment between these versions. Notes The affected models are exported using standard CoreML conversion pipelines. No custom operators or third-party CoreML runtime layers are used. The issue reproduces consistently across multiple machines. It would be helpful to know if there were changes to CoreML’s tensor layout, precision handling, or MLCompute backend between macOS 26.0.1 and 26.1 Beta, or if this is a known regression in the current beta.

Hardware: • Mac Studio (M1 Ultra) • Apple Silicon • Sufficient free disk space (~35GB+ available) • SIP enabled • 4 local Time Machine snapshots present Current System: • Already running macOS Tahoe beta • Attempting upgrade to macOS Tahoe 26.4 Beta (Build 25E5207k) Primary Issue: Software Update downloads successfully, then moves to “Preparing…”. It stalls at “About 5 minutes remaining” for ~10–15 minutes and fails with: “Failed to prepare the software update. Please try again. An error occurred while downloading the selected updates.” The error appears network-related, but download always completes. Observed Behaviour: • “Checking for Updates” completes in <3 minutes. • softwareupdated and mobileassetd CPU usage <1%. • softwareupdate --history shows no record of the failed beta install. • No excessive system load or obvious disk pressure. Steps Already Attempted: 1. Standard Software Update retries • Multiple download/retry cycles from System Settings. • Same Preparing failure every time. 2. Permissions / Disk Access • Granted Terminal Full Disk Access. • SIP remains enabled. • Some system-protected locations still return “Operation not permitted”. 3. Cache / State Cleanup Attempts • Removed /Library/Updates/*. • Cleared temporary softwareupdate folders under /private/var/tmp. • Attempted MobileAsset cache cleanup where permitted. • Killed softwareupdated and mobileassetd processes (auto-restarted by launchd). 4. Beta Channel Reset • Turned Beta Updates OFF in System Settings. • Rebooted. • Re-enabled Beta Updates. • Forced catalog refresh via softwareupdate -l. 5. Snapshot Check • tmutil listlocalsnapshots / shows only 4 snapshots (normal range). 6. Full Installer Workaround softwareupdate --list-full-installers shows: • macOS Tahoe Beta 26.4 (25E5207k) • Tahoe 26.3 / 26.2 / 26.1 • Sequoia / Sonoma / Ventura / Monterey installers Downloaded installer via: softwareupdate –fetch-full-installer –full-installer-version 26.4 Installer downloaded correctly: /Applications/Install macOS Tahoe Beta.app 7. startosinstall Method (Apple Silicon optimized) Attempted install with: sudo “/Applications/Install macOS Tahoe Beta.app/Contents/Resources/startosinstall” –user –agreetolicense –nointeraction –forcequitapps –rebootdelay 30 –passprompt Authorization succeeds, installer begins preparing, but installation still ultimately fails. Additional Notes: • CPU usage remains low during failure. • No excessive snapshot count. • Error messaging consistently references download/network even though download completes. • Issue appears to occur during cryptex/asset preparation phase rather than initial download. Question for Apple / other developers: Has anyone else seen Tahoe 26.4 beta fail specifically during the Preparing phase on Apple Silicon (especially Ultra-class chips)? Looking for confirmation whether this is a known MobileAsset or cryptex staging issue, or if logs indicate a deeper APFS / volume-owner authorization problem.

I work on an SDK, and one of the ways we distribute it is as a pre-compiled static XCFramework. As far as I know, it’s the nature of a static framework to not contain symbols since the framework will be embedded in the final app binary, and the symbols should then be generated. However, when testing the "Validate" function of the Xcode 16 deployment process, our users are receiving a warning that says the framework does not contain symbols. Is my assumption about static frameworks and symbols incorrect? Could this be a bug in Xcode 16? Should we modify something in our framework to inform Xcode that symbols are not needed?

Hi everyone, I’m testing an iPhone app called Steady through TestFlight and would love honest feedback. Steady is built for the moment right before someone acts on an urge they may regret. The core idea is to create a short pause before action, then let the user log what happened so they can spot patterns over time. Use cases could be things like sending a text you shouldn’t, reacting too fast, opening something you wanted to avoid, or other impulsive moments. I’m mainly looking for feedback on three things: Does the concept feel useful in real life? Is the flow clear or confusing? What feels unnecessary or missing? TestFlight link: https://testflight.apple.com/join/YsnDsGR5 Appreciate any honest feedback.

On one of my machines (new MacMini M4Pro) I can’t add any new VPN configuration, doesn’t matter what I use. Trying to set up Tailscale, I get to the point where Tailscale brings up the "Allow VPN configuration" panel. If I hit the "Allow VPN Configuration" button, then macOS pops up its own panel: "Tailscale" Would Like to Add VPN Configurations All network activity on this Mac may be filtered or monitored when using VPN. [Allow] [Don’t Allow] I hit the allow button, and after a short wait the Tailscale panel shows in red "You must allow this to use Tailscale". I can repeat this as often as I want, but Tailscale isn’t added to the VPN configurations. If I use any other third party VPN app, I get similar results: nothing gets added to the VPN configurations. If I use macOS’s System Settings and hit the "Add VPN Configuration" pop-up menu in the VPN section, and e.g. add an IKEv2 setup, it ask me to authenticate, and then provides me with the panel into which to put the relevant settings. I enter some test settings, and then hit the [Create] button... …and nothing! The new VPN configuration doesn’t show up in the list, where it should show up. It’s as if I had done nothing. No matter what I do, the VPN configurations are immutable. I suspect that some folder somewhere is either missing or for some reason has the wrong permissions. Where are these VPN configurations stored? Any other hints on how to fix this? Reinstalling the OS does’t fix this, since this issue persisted across various betas of macOS26

Title says it all, so I get to 5 minutes left, and then the error message 'failed to prepare update' appears. I've done this for about a week now and the same thing happens. Does anyone have any insight to this problem?

In my tabview i set a safeAreaBar topPanel, under i have contentview. That ignore safeArea.top so feed go under. What is the best Way to have a the first post in content appear under (under the bottom) if the safeareabar. I use list with foreach. Do we measure the height or is it some smart tips?
