How to iterate through array of objects in Swift?

Question

i have objects

var person1 = Person()
person1.name = \"Joe\"
person1.lastName = \"Doe\"
person1.age = 21

var person2 = Person()
person2.name = \"Julia\"
person2         


        

Answer 1

An interesting way of solving this would be to leverage the flatMap function of Swift.

var array = [[person1, person2, person3], [person9, person10, person11]]

let flatArray = array.flatMap { $0 }

flatArray now is [person1, person2, person3, person9, person10, person11] of type Array.

Then you can iterate on flatArray to find what you want :

for person in flatArray {
    if person.name == "Masha" {
        // Do something
    }
}

You could even go further by using Swift 2.0 because it allows you to put a where clause in the for :

for person in flatArray where person.name == "Masha" {
    // Do something
}
