8,155 PointsHow does optional binding work with the first example of force unwrapping?
The only way they teach you how to use optional binding is from a dictionary. how does this work with the first example bellow:
struct Person { let firstName: String let middleName: String? let lastName: String
func getFullName() -> String {
if middleName == nil {
return firstName + " " + lastName
} else {
return firstName + " " + middleName! + " " + lastName
}
}
}
let me = Person(firstName: "Chris", middleName: nil, lastName: "Lopez")

struct Person {
let firstName: String
let middleName: String?
let lastName: String
func getFullName() -> String {
if let MiddleName = middleName {
return firstName + " " + MiddleName + " " + lastName
} else {
return firstName + " " + lastName
}
}
}
let me = Person(firstName: "Chris", middleName: nil, lastName: "Lopez")
