var defaultNum = 1
class MyClass {
var num: Int {
get { _num ?? defaultNum }
set { _num = newValue }
}
private var _num: Int?
}
let c = MyClass()
print("initial \(c.num)") // ✅ == 1
// changing the default changes the value returned
defaultNum = 2
print("dynamic \(c.num)") // ✅ == 2
// once the property is set, uses that value
c.num = 5
print("set \(c.num)") // ✅ == 5
