macOS-14 images missing iOS 18 Simulator

[chadseippel]

Description

While running Xcode builds against the macOS-14 pipelines, xcodebuild fails because it cannot find a scheme for iphoneos18.0. It looks like even though Xcode16.0 is installed, it's missing the iOS 18 Simulator.

If I run this command before running xcodebuild, it succeeds - "sudo xcodebuild -downloadPlatform iOS". But it adds around ~10 minutes to the build time. Can the macOS14 images have the iOS 18 simulator pre-installed?

Is it regression?

No

Expected behavior

iOS 18 Simulator does not need to be manually installed

Actual behavior

iOS 18 Simulator is missing and xcodebuild fails in Xcode16.0

Repro steps

Use macOS14 image with Xcode16 installed, run xcodebuild against iphoneos scheme

Hey @chadseippel!

That's true. We didn't installed Xcode 16.0 Beta 1 runtimes for macOS-14 images, only for macOS-14-arm64. We are working on it right now. Will provide the additional information later. Sorry for inconsistency. 😞
