Array search function not working in Swift

Question

I confess feeling little stupid, but after hours of trying I have to ask:

class AGE {

     static func getAge() -> Int {

        var age: Int

        for i

I tested Vadian's answer and it seems to be the correct one as per your requirements.

Nonetheless, here are other suggestions:

First, create another instance of your array based on your Person Struct:

var filteredPerson = [Person]()

If you want to search your dataArray for the age based on the first name:

func getAge(of name: String){
     filteredPerson = dataArray.filter { $0.name == name }
     print (filteredPerson[0].age) }

To get the age value of "Steven":

getAge(of: "Steven")

You'll get the Result: 23.

Note that you can also just get the Int value via return:

func getAge(of name: String) -> Int {
     filteredPerson = dataArray.filter { $0.name == name }
     return filteredPerson[0].age }

On the other hand, if you have lots of Persons in your list with the same name, and you want to get the age value of a specific Person, just add the lastName parameter:

func getAge(name: String, lastName: String){
     filteredPerson = dataArray.filter { $0.firstName == name && $0.lastName == lastName }
     print (filteredPerson[0].age) }

And then get the age value via calling:

getAge(name: "Steven", lastName: "Miller")

Hope this helped someone in some way :)
