Hi sourabhgupta, I’m deploying the new GM Seed 2 image today. We are currently limited by network speeds. We have to deploy the 70gb image to 100s of machines in the data-center each time that we release a new image. Marc ---

I’m seeing this as well. Found this post for xctool that worked around it by adding `--standalone` to that simctl call. > But that looks like a change that would be needed to be made to fastlane if i understand it correctly. ---

ok. I have managed to fix the issue by using custom ruby version suggested by you. But I still think xcode11 tools should be installed. ---

OK, I’ve gotten to the bottom of the issue with devices. I think it’s a documentation issue. We install a bunch of SDKs. The devices themselves are part of Xcode. For the Xcode 11.0 image here is what’s installed: ```auto $ xcrun simctl list devicetypes == Device Types == iPhone 4s (com.apple.CoreSimulator.SimDeviceType.iPhone-4s) iPhone 5 (com.apple.CoreSimulator.SimDeviceType.iPhone-5) iPhone 5s (com.apple.CoreSimulator.SimDeviceType.iPhone-5s) iPhone 6 Plus (com.apple.CoreSimulator.SimDeviceType.iPhone-6-Plus) iPhone 6 (com.apple.CoreSimulator.SimDeviceType.iPhone-6) iPhone 6s (com.apple.CoreSimulator.SimDeviceType.iPhone-6s) iPhone 6s Plus (com.apple.CoreSimulator.SimDeviceType.iPhone-6s-Plus) iPhone SE (com.apple.CoreSimulator.SimDeviceType.iPhone-SE) iPhone 7 (com.apple.CoreSimulator.SimDeviceType.iPhone-7) iPhone 7 Plus (com.apple.CoreSimulator.SimDeviceType.iPhone-7-Plus) iPhone 8 (com.apple.CoreSimulator.SimDeviceType.iPhone-8) iPhone 8 Plus (com.apple.CoreSimulator.SimDeviceType.iPhone-8-Plus) iPhone X (com.apple.CoreSimulator.SimDeviceType.iPhone-X) iPhone Xs (com.apple.CoreSimulator.SimDeviceType.iPhone-XS) iPhone Xs Max (com.apple.CoreSimulator.SimDeviceType.iPhone-XS-Max) iPhone Xʀ (com.apple.CoreSimulator.SimDeviceType.iPhone-XR) iPhone 11 (com.apple.CoreSimulator.SimDeviceType.iPhone-11) iPhone 11 Pro (com.apple.CoreSimulator.SimDeviceType.iPhone-11-Pro) iPhone 11 Pro Max (com.apple.CoreSimulator.SimDeviceType.iPhone-11-Pro-Max) iPad 2 (com.apple.CoreSimulator.SimDeviceType.iPad-2) iPad Retina (com.apple.CoreSimulator.SimDeviceType.iPad-Retina) iPad Air (com.apple.CoreSimulator.SimDeviceType.iPad-Air) iPad mini 2 (com.apple.CoreSimulator.SimDeviceType.iPad-mini-2) iPad mini 3 (com.apple.CoreSimulator.SimDeviceType.iPad-mini-3) iPad mini 4 (com.apple.CoreSimulator.SimDeviceType.iPad-mini-4) iPad Air 2 (com.apple.CoreSimulator.SimDeviceType.iPad-Air-2) iPad Pro (9.7-inch) (com.apple.CoreSimulator.SimDeviceType.iPad-Pro--9-7-inch-) iPad Pro (12.9-inch) (com.apple.CoreSimulator.SimDeviceType.iPad-Pro) iPad (5th generation) (com.apple.CoreSimulator.SimDeviceType.iPad--5th-generation-) iPad Pro (12.9-inch) (2nd generation) (com.apple.CoreSimulator.SimDeviceType.iPad-Pro--12-9-inch---2nd-generation-) iPad Pro (10.5-inch) (com.apple.CoreSimulator.SimDeviceType.iPad-Pro--10-5-inch-) iPad (6th generation) (com.apple.CoreSimulator.SimDeviceType.iPad--6th-generation-) iPad Pro (11-inch) (com.apple.CoreSimulator.SimDeviceType.iPad-Pro--11-inch-) iPad Pro (12.9-inch) (3rd generation) (com.apple.CoreSimulator.SimDeviceType.iPad-Pro--12-9-inch---3rd-generation-) iPad mini (5th generation) (com.apple.CoreSimulator.SimDeviceType.iPad-mini--5th-generation-) iPad Air (3rd generation) (com.apple.CoreSimulator.SimDeviceType.iPad-Air--3rd-generation-) Apple TV (com.apple.CoreSimulator.SimDeviceType.Apple-TV-1080p) Apple TV 4K (com.apple.CoreSimulator.SimDeviceType.Apple-TV-4K-4K) Apple TV 4K (at 1080p) (com.apple.CoreSimulator.SimDeviceType.Apple-TV-4K-1080p) Apple Watch - 38mm (com.apple.CoreSimulator.SimDeviceType.Apple-Watch-38mm) Apple Watch - 42mm (com.apple.CoreSimulator.SimDeviceType.Apple-Watch-42mm) Apple Watch Series 2 - 38mm (com.apple.CoreSimulator.SimDeviceType.Apple-Watch-Series-2-38mm) Apple Watch Series 2 - 42mm (com.apple.CoreSimulator.SimDeviceType.Apple-Watch-Series-2-42mm) Apple Watch Series 3 - 38mm (com.apple.CoreSimulator.SimDeviceType.Apple-Watch-Series-3-38mm) Apple Watch Series 3 - 42mm (com.apple.CoreSimulator.SimDeviceType.Apple-Watch-Series-3-42mm) Apple Watch Series 4 - 40mm (com.apple.CoreSimulator.SimDeviceType.Apple-Watch-Series-4-40mm) Apple Watch Series 4 - 44mm (com.apple.CoreSimulator.SimDeviceType.Apple-Watch-Series-4-44mm) Apple Watch Series 5 - 40mm (com.apple.CoreSimulator.SimDeviceType.Apple-Watch-Series-5-40mm) Apple Watch Series 5 - 44mm (com.apple.CoreSimulator.SimDeviceType.Apple-Watch-Series-5-44mm) ``` ```auto $ xcrun simctl list runtimes == Runtimes == iOS 11.4 (11.4 - 15F79) - com.apple.CoreSimulator.SimRuntime.iOS-11-4 iOS 12.2 (12.2 - 16E226) - com.apple.CoreSimulator.SimRuntime.iOS-12-2 iOS 13.0 (13.0 - 17A577a) - com.apple.CoreSimulator.SimRuntime.iOS-13-0 tvOS 12.2 (12.2 - 16L225) - com.apple.CoreSimulator.SimRuntime.tvOS-12-2 tvOS 13.0 (13.0 - 17J577) - com.apple.CoreSimulator.SimRuntime.tvOS-13-0 watchOS 5.2 (5.2 - 16T224) - com.apple.CoreSimulator.SimRuntime.watchOS-5-2 watchOS 6.0 (6.0 - 17R575) - com.apple.CoreSimulator.SimRuntime.watchOS-6-0 ``` And then you can create any combination of these: ```auto bash-3.2$ xcrun simctl create iphone-x-13-0 "iPhone X" com.apple.CoreSimulator.SimRuntime.iOS-13-0 134D2D6E-2D83-40E3-A784-6EA53B4916BA ``` ---

I’ve re-built our docs with a new format for listing the devices and SDKs: [https://circle-macos-docs.s3.amazonaws.com/image-manifest/v1226/index.html](https://circle-macos-docs.s3.amazonaws.com/image-manifest/v1226/index.html) This now shows 2 sections: devices and runtimes, split out separately. ---

Hi Marc, Thanks for improving this! I’m new to CircleCi and so have what is probably a basic question: is the build image is re-created raw for every build so we have to create the simulator device+os combination we want for every build? Thanks. ---

Yes, we tear down the VM after every job is complete, all jobs start in a fresh VM. to be honest, I’m not sure if Xcode requires that you create the simulator, or if it will create the simulator for you when you try to run tests on it. I guess you would have steps like this: ```auto steps: - checkout ... - run: name: Create Devices command: xcrun simctl create iphone-x-13-0 "iPhone X" com.apple.CoreSimulator.SimRuntime.iOS-13-0 - run: name: Run Tests command: fastlane scan --workspace "Example.xcworkspace" --scheme "AppName" --device iphone-x-13-0 ``` Or more declaritively: ```auto environment: SCAN_DEVICE: iphone-x-13-0 steps: - checkout ... - run: name: Create Devices command: xcrun simctl create "$SCAN_DEVICE" "iPhone X" com.apple.CoreSimulator.SimRuntime.iOS-13-0 - run: name: Run Tests command: fastlane scan --workspace "Example.xcworkspace" --scheme "AppName" ``` This is all untested, btw ^ ---
