     Type:  defect   |     Status:  new
 Priority:  Normal   |  Milestone:
Component:  ports    |    Version:  2.3.4
 Keywords:  rmtrash  |       Port:  rmtrash
---------------------+--------------------------------
 Several compile errors related to unknown property attribute 'class' in
 Foundation.framework/Headers.
 The following is the first of many:

 {{{
   :info:build /usr/bin/clang -Os -arch x86_64 -framework Foundation -arch
 x86_64 rmtrash.m -o rmtrash
   :info:build In file included from rmtrash.m:1:
   :info:build In file included from
 /System/Library/Frameworks/Foundation.framework/Headers/Foundation.h:10:
   :info:build In file included from
 /System/Library/Frameworks/Foundation.framework/Headers/NSArray.h:5:
   :info:build
 /System/Library/Frameworks/Foundation.framework/Headers/NSObject.h:44:12:
 error: unknown property attribute 'class'
   :info:build @property (class, readonly) BOOL supportsSecureCoding;
   :info:build            ^
 }}}

 Note that I'm running MacPorts compiled from source on the macOS Sierra
 Public Beta 1
