I'm trying to download an iOS Simulator runtime in Xcode 26.2 or 26.1 on macOS 26.1, but the download keeps failing with the following error: Download failed.
Domain: DVTDownloadableErrorDomain
Code: 41
Failed fetching catalog for assetType (com.apple.MobileAsset.iOSSimulatorRuntime), serverParameters ({ RequestedBuild = 23C54;}) Domain: DVTDownloadsUtilitiesErrorDomain.
Code: -1.
Download failed due to a bad URL. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) Domain: com.apple.MobileAssetError.Download Code: 49 User Info: {checkConfiguration = 1;}
macOS & Xcode Info:
macOS Version: 26.1 (Build 25B78)
Xcode Version: 26.2 (24553) (Build 17C52)
What I've tried so far:
-
Formatted my Mac and reinstalled Xcode multiple times.
-
Completely deleted Xcode and its related files several times (/Applications/Xcode.app, caches, preferences).
-
Tried different internet connections from multiple locations.
-
Checked Apple servers and verified network.
-
Attempted downloading other simulator runtimes (fail).
but download fails immediately with DVTDownloadableErrorDomain Code 41 and bad URL error.
Question:
How can I fix the simulator download issue in Xcode 26.2 on macOS 26.1? Is there a known workaround for the bad URL / catalog download error?
