Taken from Swift documentation
If a protocol requires a property to be gettable and settable, that property requirement canβt 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 itβs valid for the property to be also settable if this is useful for your own code.
