Simulators are installed as part of the iOS SDK.

Hi @d-philipson We began our weekly deployment of macOS 14 and macOS 14-arm64 images on Monday. The current Xcode version, 16.2 Release Candidate along with iOS 18.2 SDK, is expected to be available within 1–2 days. We will provide an update here once the VM rollout is complete. Thank you for your patience.

@sureshe456 Well Xcode 16.2 was available when I tried to build, but the 18.2 SDK wasn't, so I guess the SDK had been initially missed from the deployment?

Yes, same here. My job ran on Xcode 16.2 which was confirmed by the job output from the Xcode@5 step. I pasted the exact worker VM identifier into my issue so you can confirm this by looking up the deployment image for that VM.
