Gettable and Settable

Wondering what a gettable and settable variable was

1 Answer

If a protocol requires a property to be gettable and settable, that property requirement can’t be fulfilled by a constant stored property or a read-only computed property. If the protocol only requires a property to be gettable, the requirement can be satisfied by any kind of property, and it’s valid for the property to be also settable if this is useful for your own code.
