After updated to Tahoe 26.2 and Xcode 26.2 it seems to have forgotten the Model Provider I had configured. I create a new Model Provider and it works fine, until I exit Xcode. When I open Xcode again my Model Provider is gone. It all worked fine before I did the updates of MacOS and Xcode.

Thank you for your post, which is indeed quite interesting. It appears that the update to macOS Tahoe 26.2 and Xcode 26.2 may have reset some of your configurations or introduced a bug affecting the saving of Model Providers. Have you installed Xcode 26.2 from the App Store or have you downloaded it from the developer’s website? What’s the build number? This issue has only occurred once after installation, and since then, it has been functioning correctly. However, it is important to determine whether this is a recurrence issue or if it has resolved itself after selecting the model. Ensure that your project settings are correctly pointing to your Model Provider. Sometimes updates can revert or misplace these configurations. Double-check that there is no additional update for Xcode 26.2.1 or later that might address this specific issue. Has anyone else experienced this issue? Albert Pascual

Thank you for the post and the image. Those have proven to be extremely helpful. I have two thoughts in mind regarding your situation. First, have you installed the latest version of Xcode available on the App Store? Second, are you targeting the release versions of iOS and watchOS? If both of these conditions are met, the next and most crucial step is to ensure that you have filed a bug report using the sysdiagnose tool from your machine. Additionally, it is essential to have the logs from the Xcode build that indicate the errors. My apologies that you are using Xcode Cloud quota. I will be honest that I do not know how that part works, but I will get familiar with it soon. If you have any questions about filing a bug report, take a look at Bug Reporting: How and Why?

I am trying to upgrade my app to use Xcode 26 and I cannot get my tests to launch. I am trying to launch tests to the simulator, and I always get this error after 300 second timeout: encountered an error (The test runner hung before establishing connection.) There are no other errors getting logged. I can run to the same simulator just fine, and in Xcode 16 the tests launch with no issues. The tests also run fine on an actual iPhone. Thanks in advance.
Same issue encountered on XCode 26.2 with Simulator iPhone 17 Pro in iOS 26.2. The tests won't run in simulators because of issue The test runner hung before establishing connection., but they run fine on physical devices and iPhone 17 Pro Simulator in iOS 26.1. The FB report id is FB21363735, which is still collecting diagnostics and will be sent in a moment.

Hi all, Has anyone else run into this issue in Xcode 26? I’m logged into my paid ChatGPT Plus account, but the Xcode integration doesn’t seem to recognize the subscription. After a short period of use, I get the following error: “Over daily limit. ChatGPT in Xcode will be unavailable for up to 24 hours. For higher limits, sign in with a paid ChatGPT account.” Since I’m already signed in with a paid account, this looks like either a bug or a limitation specific to Xcode. Is this expected behavior, or has anyone found a workaround to make Xcode properly recognize Plus accounts? Thanks in advance for any guidance.

I want to make a app that indicates that the app is recording in the background using a indicator on the dynamic island or on the top of the phone screen but i can't figure it out on Xcode. Saw a guy do it by making live activities true but can't seem to find that option in background mode in capabilities. any ideas?

Out of nowhere I got some red banner on top of my iPhone 13 mini / iOS 17.5. I cannot pin point the root cause of this. What I can say is that it only happens to Simulators of a certain type, e.g. iPhone 12 and 13 mini, but not iPhone 14 for example. I have installed Xcode 26.1.0 and 26.1.1, out of which 26.1.0 is selected: $ xcode-select -p /Applications/Xcode-26.1.0.app/Contents/Developer And following runtimes: $ xcrun simctl runtime list == Disk Images == -- iOS -- iOS 17.5 (21F79) - CF933623-A258-44F8-B248-C0F25C0C343B (Ready) iOS 26.1 (23B80) - D11C3CDC-EE3D-44CC-8B92-9B7D00B54B0B (Ready) Total Disk Images: 2 (14.6G) Installing the newer 26.1 23B86 runtime doesn't help either.
I'm using Xcode cloud to create testflight builds, and I noticed that a few weeks ago these builds no longer contain any What to Test info. We include a TestFlight/WhatToTest.de-DE.txt file in our repo, and that file seems to be picked up correctly, at least the logs say Saving “What to test” notes Found notes for de-DE Any ideas of what I should be looking into or change?
@DTS Engineer thanks for the information. you must build your app against the iOS 26.2 and iPadOS 26.2 SDKs and later, with Xcode 26.2 (17C52) and later But a clarification needed: is using Xcode 26 required only to access all API ? Can you confirm that to keep the app updatable on AppStore, it is enough to update meta data on age ratings and submit the app, even if compiled with Xcode 16 ?

Hi @DTS Engineer , Thanks a lot for your clarifications again!! I’m working with the NETransparentProxyProvider class for a network extension app in my macOS. However, I’ve encountered an issue where the Transparent Proxy extension does not activate when the system is offline (network disabled). Here are the details: Content Filter extension is active and functioning properly(offline as well) Both the Transparent Proxy and Content Filter extensions are under the same Xcode target. I can see the Transparent Proxy extension listed in Settings → Network → Filters & Proxies, but it shows as Disabled.(offline) My question: Is an active network connection required for the NETransparentProxyProvider extension to be enabled/activated, even temporarily, during installation? Background: The environment where I’m installing the system extension doesn’t have network access (e.g., in sandboxed VMs). Once installed, the extensions are always running, but the main app process (Xcode target 1) is starte

Hi all, I have a working macOS (Intel) system extension app that currently uses only a Content Filter (NEFilterDataProvider). I need to capture/log HTTP and HTTPS traffic in plain text, and I understand NETransparentProxyProvider is the right extension type for that. For HTTPS I will need TLS inspection / a MITM proxy — I’m new to that and unsure how complex it will be. For DNS data (in plain text), can I use the same extension, or do I need a separate extension type such as NEPacketTunnelProvider, NEFilterPacketProvider, or NEDNSProxyProvider? Current architecture: Two Xcode targets: MainApp and a SystemExtension target. The SystemExtension target contains multiple network extension types. MainApp ↔ SystemExtension communicate via a bidirectional NSXPC connection. I can already enable two extensions (Content Filter and TransparentProxy). With the NETransparentProxy, I still need to implement HTTPS capture. Questions I’d appreciate help with: Can NETransparentProxy capture the DNS fields I need (dns_

Here’s what’s going on and how I fixed it locally. Once you install and run a newer Xcode (for example 26.2), it performs a CoreSimulator migration and writes system-wide frameworks into /Library/Developer/PrivateFrameworks. This migration is global and there’s no rollback mechanism. Even if you delete Xcode 26.2 and keep using Xcode 26.1.1, the older Simulator binary still loads CoreSimulator frameworks from the system location, not from inside the Xcode bundle. So you end up in a situation where Simulator.app is launched from /Applications/Xcode-26.1.1.app/Contents/Developer/Applications/Simulator.app/Contents/MacOS/Simulator but it’s actually using newer system frameworks like: /Library/Developer/PrivateFrameworks/CoreSimulator.framework/Versions/A/CoreSimulator /CoreSimDeviceIO.framework /SimPasteboardPlus.framework /CoreSimulatorUtilities.framework In my case the CoreSimulator version there was already 1051.17.7, which clearly came from Xcode 26.2.

The developer downloads page now lists an Xcode 26.1 which was released on 11th Dec (the original Xcode 26.1 was posted on 3rd Nov). Strangely, this new Xcode 26.1 has a CFBundleShortVersionString of 26.1.1, and a DTXcodeBuild of 17B55 % ls -ln total 4413136 -rw-r--r--@ 1 503 20 2259523057 16 Dec 19:01 Xcode_26.1_Apple_silicon.xip % xip --expand Xcode_26.1_Apple_silicon.xip xip: signing certificate was Software Update (validation not attempted) xip: expanded items from /Users/me/Downloads/temp/Xcode_26.1_Apple_silicon.xip % plutil -p Xcode.app/Contents/Info.plist | grep CFBundleShort CFBundleShortVersionString => 26.1.1 % plutil -p Xcode.app/Contents/Info.plist | grep DTXcodeBuild DTXcodeBuild => 17B55 17B55 does correspond to the original Xcode 26.1 final release. The Xcode 26.1.1 release that was previously posted had a DTXcodeBuild of 17B100, though. The pairing of 26.1.1 and 17B55 looks new and probably a packaging error?
