I've recently updated to Xcode 26.3 and I can't download any iOS Simulator Runtime from 26.2 to 18.0, every download gives me:

Download failed.
Domain: DVTDownloadableErrorDomain
Code: 41
User Info: {
    DVTErrorCreationDateKey = "2026-03-03 16:14:50 +0000";

System Information

macOS Version 26.4 (Build 25E5218f)
Xcode 26.3 (24587) (Build 17C529)
Timestamp: 2026-03-03T17:14:50+01:00

I tried cleaning every cache, and logging in and out of my account.

I saw some reddit posts where they suggested to check out VPNs, host files and other stuff but everything was okay, also I can reach apple cdns etc.

I also tried using Xcode beta 26.4 and going back to 26.2 but still the same problem.

Anyone has a solution?

After completely losing my mind on this I solved it! I moved /System/Library/AssetV2/com_apple_MobileAsset_iOSSimulatorRuntime to an external drive to free some space and that broken the download. I simply removed the symlink without restoring the original folder and everything went back to normal.

Hope this helps somebody else!

I have the same persistent issue on Xcode 26.6 (17F113).

Xcode Settings → Components repeatedly fails downloading iOS 26.5.1 + iOS 26.5 Simulator with DVTDownloadableErrorDomain Code 41.

xcodebuild -downloadPlatform iOS reaches “Preparing to download” but does not install or export a runtime. Earlier diagnostics reported com.apple.MobileAssetError Code 53: the download was not scheduled or could not complete in time.

I have no VPN, no proxy, no Apple entries in /etc/hosts, and over 300 GB free disk space. Xcode’s first-launch component check reports no updates.
