Error on Xcode when typing function

I am typing the function on to Xcode the way Amit has it but I keep getting two error pop ups that will not let me complete the function. Note I am using Xcode 7.0. I type it like this:

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

var found = false

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

}

searchNames(name: "John")

and get the following errors: Binary Operator == cannot be applied to operands type "String" and [String] and when I remove one of the = I get the following error Cannot assign to value: 'n' is a 'let' constant
