This exists to use along with `OBSBFTask` and `OBSBFTaskCompletionSource`.
|
|
Instead of returning a `OBSBFTask` with no generic type, or a generic type of 'NSNull'
|
when there is no usable result from a task, we use the type 'OBSBFVoid', which will always have a value of `nil`.
|
|
This allows you to provide a more enforced API contract to the caller,
|
as sending any message to `OBSBFVoid` will result in a compile time error.
