Thanks for your reply, Rien. I just tried this again, and now it seems that
either is acceptable. Seems a little weird, but I guess I’d rather have more
flexibility than less.
protocol Powerable {
var isOn:Bool { get set } // Must have get and set
var usesDC:Bool { get } // Must have get, may have set
func turnOn()
func turnOff()
}
class GPS : Powerable, CustomStringConvertible {
// Either of these work
// var description: String {
// return "I am a GPS"
// }
var description:String = "I am a GPS"
var isOn: Bool = false
var usesDC: Bool = false
// does the obvious
func turnOn(){
isOn = true
}
// does the obvious
func turnOff() {
isOn = false
}
}
print(GPS()) // output: I am a GPS (both cases)
