Hi, I'm unable to download the iOS 18.5 (22F76) and iOS 18.6 (22G86) Simulator runtimes on macOS 15.6 (24G84). The issue persists across multiple versions of Xcode, including 16.4 (16F6) and Xcode 26 beta 3 (17A5276g). Symptoms: In Xcode > Settings > Platforms (Components tab), clicking “Get” for iOS 18.5 / 18.6 either does nothing or results in a download failure. CLI command sudo xcodebuild -downloadPlatform iOS fails with: Domain: DVTDownloadableErrorDomain, Code: 41 HTTP 403 Forbidden from Amazon S3/CloudFront Switching to admin user, different networks, and clean reinstall of Xcode had no effect. I also attempted manual installation using the .dmg files from the developer portal. After mounting (e.g. Xcode_15_Simulator_Runtime_iOS_18.2.dmg), I extracted iOS 18.2.simruntime, but Xcode does not recognize it. File structure inside the extracted .simruntime: Contents/ ├── Info.plist (missing runtime identifier) ├── MacOS/ ├── Resources/ └── _CodeSignature/ E
