ToolbarItem not compiling

I have a .toolbar modifier that contains ToolbarItems. The compiler is failing with 'ToolbarItem' is only available in iOS 14.0 or newer'. I have Xcode 12 beta 2 installed, the deployment target set to iOS 14 and a simulator running ios14. This looks like a beta version error. Has anyone else encountered it?
Any movement on this. Literally happening to me now.
