Xcode 9.1, VST 3 examples - build failed

Hi I am new, I download vst3 sdk and cannot compile examples on high sierra 10.13.1, xcode 9.1. I get errors in every example, delay plugin get just 1 error “C++17 is required for this header” all others as gain example 7 errors, is there workaround to compile all examples and learn developing ?

The minimun requirement is Xcode 10, you could use the shellscript which checks the needed components for VST3SDK:
VST_SDK/vst3sdk/tools/setup_macos_packages_for_vst3sdk.sh
