@_functionBuilder App Store Review

Hi Guys,

I am using Xcode 11+ and my app supports iOS 12+. I wonder if it is safe to use @_functionBuilder in my code without my app getting rejected in app store reviews.

That would be better asked at the Apple Developer Forums.

My hunch is that @_functionBuilder probably only has a source‐level effect and that it is already dealt with and gone by the time compilation is complete. They probably cannot tell whether you used it or not. But it’s only a guess; I haven’t looked at the implementation.
