Optionals being clumsy means you start to eliminate them as you write more Swift. It becomes a carefully considered decision to use an optional in your interface. And the compiler keeps you in line.

I love the compile-time optional support now and severely miss it when using languages that don't have the feature. They are brilliant when you are working with all-Swift code or Objective-C code that has been decorated with nullability keywords.

However optionals become a burden when you are working with old Objective-C code that has not been annotated.
