We’re back with our Wizard struct, and there’s one last thing I’d like to show you, that you can do with instance variables. Let’s say we want to add another stored property, like magicalCreature, and just for a moment, assign it an empty String

63 var magicalCreature = ""
63 lazy var magicalCreature = ""
63   lazy var magicalCreature = summonMagicalCreature(summoner: fullName)
var wizard = Wizard(firstName: "Gandalf", lastName: "Greyjoy")
😺Wizard(firstName: <#T##String#>, lastName: <#T##String#>, magicalCreature: <#T##String?#>)🛑
var wizard = Wizard(firstName: "Gandalf", lastName: "Greyjoy")
❌Wizard(firstName: <#T##String#>, lastName: <#T##String#>, magicalCreature: <#T##String?#>)❌
65 init(firstName: String, lastName: String) {
    
  }
66 self.firstName = firstName
self.lastName = lastName
print(wizard.magicalCreature)
wizard.fullName = "Qui-Gon Crayskull"
print(wizard.magicalCreature)
