name: Build and Test SDKHostApp scheme using any available iPhone simulator

# macos-26 is required: only this image's installed Xcodes include

# 26.4.1+, where the stricter protocol-witness availability check

# this PR exists to fix (issue #310) lives. macos-15 tops out at

# Xcode 26.3, which does not exercise the check and would let

# regressions of the @available annotations slip through.
