When running an Xcode Cloud workflow pinned to Xcode 26.1, macOS 26.1 and using a Test Destination for iPhone 15 Pro and iOS 26.1, the following error appears in the xcodebuild-build-for-testing.log: 2025-11-13T19:08:31.855137440Z xcodebuild: error: Unable to find a destination matching the provided destination specifier: 2025-11-13T19:08:31.855318998Z { platform:iOS Simulator, id:704F84C8-025F-4F70-B2D9-FF19B7DC098F } 2025-11-13T19:08:31.855362640Z 2025-11-13T19:08:31.855370957Z Ineligible destinations for the "Inbound" scheme: 2025-11-13T19:08:31.855381964Z { platform:iOS, id:dvtdevice-DVTiPhonePlaceholder-iphoneos:placeholder, name:Any iOS Device, error:iOS 26.1 is not installed. Please download and install the platform from Xcode > Settings > Components. } This can be fixed if ci_pre_xcodebuild.sh is updated with the following: # Get Xcode major version # `xcodebuild -version` returns something like: # Xcode 26.0.1 # Build version 17A400 XCODE_VERSION=$(xcodebuild -version | head -n 1 | awk '{print $2}' | cut -d. -f1) if [ "$XCODE_VERSION" -ge 26 ]; then if xcodebuild -downloadPlatform iOS >/dev/null 2>&1; then echo "iOS platform is installed" else echo "iOS platform is not installed. Failing the build." exit 1 fi fi Changing the workflow to use "Latest Release" of Xcode (26.1), macOS (26.1) and the Latest Test Destination iOS (26.1) version provided also does not work.
