Xcode 26.1.1
Xcode 26.1.1 includes Swift 6.2.1 and SDKs for iOS 26.1, iPadOS 26.1, tvOS 26.1, macOS 26.1, and visionOS 26.1. Xcode 26.1.1 supports on-device debugging in iOS 15 and later, tvOS 15 and later, watchOS 8 and later, and visionOS. Xcode 26.1.1 requires a Mac running macOS Sequoia 15.6 or later.
It’s hard to see what’s new in this version because Apple is showing a combined list of release notes for 26.1 and 26.1.1. The old page for 26.1 is gone and doesn’t seem to be in the Internet Archive, either. Luckily, I had saved a copy in EagleFiler. The only new item seems to be:
Fixed: Users interacting with ChatGPT in Xcode might experience performance issues when the assistant is applying code changes. (163507099)
So I guess the simulator and visionOS issues aren’t fixed.

Xcode 26.1.1 was a mistake

And.... 26.1.1 wants to download iPadOS 26.1 and returns the following error:
"Download from live asset server could not get an asset matching the requested one. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime)"
(1) I do not need the simulator - it's never worked if you are using Coreimage.
(2) This was not present in Xcode 26.1, which ws released exactly...one...week...ago.
This is crazy. Way to go Apple.
Follow up. I was about 6 hours ago that Xcode 26.1 worked fine for iOS 26.1. Now? I'm getting the same error for iOS! I get that Apple considers the need to install what they call a "simulator" but actually is the SDK. It wants 26.1, which WAS installed 6 hours ago.
DO NOT DOWNLOAD.
Newest update. Again, If Xcode 26.1.0 is working with iOS/iPadOS 26.1, please, do Xcode 26.1.1.
Here's a thread on the developer forum:

As of now, this thread has 457 view and, 15 replies. Some suggestions.... everything from reinstall 26.0.1 (yes, not 26.1.0) to command line installs. Here's the one that worked for me:
> This worked for me. Download and install the "Command_Line_Tools_for_Xcode_26.1.dmg" Run Xcode and iOS 26.1 Runtime should now download properly.
Thanks to @mibarret. You know, long before there was AI slop, there was app release slop. Apple must be competing for being the leader anymore.
Any news on the neverending macOS app icon story, i.e. having proper icons for both, Tahoe and older OSs?

This also annoyed me (especially between beta versions), so I started maintaining a Git repository to keep track of all of Apple's developer release notes:

Here's what changed from Xcode 26.1 to 26.1.1:

Does anyone know if I can download the IOS 26.1 Platform manually. Downloading it from the XCode interface takes very long time.
