My macOS app compiles and runs fine, but since switching to Xcode 11, I can no longer debug from breakpoints. The debugger always crashes with a bunch of messages like this:warning: Swift error in scratch context: /foobar/Foo-Bridging-Header.h:14:9: note: in file included from /foobar/Foo-Bridging-Header.h:14: #import "TPPreciseTimer.h" ^ error: /foobar/Timer/TPPreciseTimer.h:9:9: error: 'Foundation/Foundation.h' file not found #import <Foundation/Foundation.h> ^ /foobar/Timer/TPPreciseTimer.h:9:9: note: did not find header 'Foundation.h' in framework 'Foundation' (loaded from '/System/Library/Frameworks') #import <Foundation/Foundation.h> ^ error: failed to import bridging header '/foobar/Foo-Bridging-Header.h' . Shared Swift state for Foo has developed fatal errors and is being discarded. REPL definitions and persistent names/types will be lost. Message from debugger: The LLDB RPC server has crashed. The crash log is located in ~/Library/Logs/DiagnosticReports and has a prefix 'lldb-rpc-server'. Please file a bug and attach the most recent crash log.Anyone know a workaround for something like this?My coworkers still on Xcode 10.3 are not having this issue with the same codebase.

Xcode 11 Interface Builder groups layout constraints into Horizontal and Vertical. While this is sometimes useful, I personally find it more helpful to organize constraints hierarchically. Is there any option to get the old Sibling & Ancestor and Descendents groupings in Xcode 11?
