Add macOS_Xcode26 and iOS_Xcode26 jobs on the macos-26 runner with Xcode 26.4 (iPhone 17 simulator for iOS). Remove iOS_Xcode152 which ran on the soon-to-be-retired macos-14 runner. Mirrors BabylonJS/BabylonNative#1642. No source changes needed — JsRuntimeHost has no iOS UI code affected by the iOS 26 deprecations.

Pull request overview
This PR updates the CI workflow to add macOS and iOS coverage for Xcode 26 on the macos-26 GitHub Actions runner, while removing the older iOS Xcode 15.2 job as macos-14 is being retired.
Changes:
- Add a new
macOS_Xcode26job using Xcode26.4onmacos-26. - Replace the
iOS_Xcode152job withiOS_Xcode26using Xcode26.4onmacos-26and aniPhone 17simulator.

Run sanitizers and thread sanitizer on Xcode 26.4 alongside the existing 16.4 sanitizer jobs, so regressions on the newer toolchain are caught without losing coverage on the current stable. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Add CI coverage for Xcode 26 (
macos-26runner) and drop Xcode 15.2.Changes
macOS_Xcode264— builds + tests onmacos-26with Xcode 26.4.macOS_Xcode264_Sanitizers— ASan/UBSan onmacos-26with Xcode 26.4.macOS_Xcode264_ThreadSanitizer— TSan onmacos-26with Xcode 26.4.iOS_Xcode264— builds + tests onmacos-26with Xcode 26.4, iPhone 17 simulator.iOS_Xcode152— themacos-14runner and Xcode 15.2 are on their way to being retired; Xcode 16.4 (macos-latest) is our baseline and Xcode 26 now exercises the latest toolchain.The Xcode 16.4 sanitizer jobs are retained alongside the new 26.4 sanitizer jobs. Major Xcode bumps have historically introduced sanitizer-runtime regressions (instrumentation gaps as the toolchain catches up to new system libraries), and TSan on arm64 is less battle-tested than on x86. Running both lets us catch regressions on the newer toolchain without losing coverage if Xcode 26 has sanitizer issues. Once Xcode 26 sanitizers have been stable for a while, the 16.4 sanitizer jobs can be dropped.
Mirrors the approach taken in BabylonJS/BabylonNative#1642. No source changes were needed — JsRuntimeHost has no iOS/macOS UI code (no
UIScreen.mainScreen,connectedScenes, orstatusBarOrientationusages), so the iOS 26 deprecations addressed in #1642 don't apply here.Dropping Xcode 15.2
Xcode 15.2 coverage came from the
macos-14runner, which is being phased out on GitHub Actions. Withmacos-latestpinned to Xcode 16.4 and the newmacos-26job exercising Xcode 26.4, the 15.2 slot is redundant and unsupported.Co-authored-by: Copilot 223556219+Copilot@users.noreply.github.com
