I’m trying to download an iOS Simulator runtime in Xcode 26.2 on macOS 26.1, but the download keeps failing with the following error:
Download failed.
Domain: DVTDownloadableErrorDomain
Code: 41
User Info: {
DVTErrorCreationDateKey = "1447-07-08 21:35:46 +0000";
}
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:
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).
Expected behavior:
Simulator runtime should download and install successfully.
Actual behavior:
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?
