Why am I getting Type 'String' does not conform to protocol 'SequenceType'?

import UIKit

func searchNames (name names: String) -> Bool { _ = ["Amit", "Andrew", "Ben", "Craig", "Dave", "Guil", "Hampton", "Jason", "Joy", "Kenneth", "Nick", "Pasan", "Zac"]

var found = false

for n in names { if n == name { found = true }

}

return found }

searchNames(name: "John")

Hey Javid,

in your for in loop you should search within the array that you created, not within the passed parameter, "names". In your if statement, this is where you should be checking if "n" is equal to the passed parameter, "names". Also I would assign the array to a variable/constant so that you can refer to it. This is what I did:

func searchNames (name names: String) -> Bool { let instructors = ["Amit", "Andrew", "Ben", "Craig", "Dave", "Guil", "Hampton", "Jason", "Joy", "Kenneth", "Nick", "Pasan", "Zac"]

    var found = false

    for n in instructors { if n == names { found = true }

    }

    return found }

searchNames(name: "Craig")

Hope that helps!
