i can’t see anything wrong with the code but it keeps telling me in the error that i messed up when calling the function.
func search(name: String) -> String? {
let names = ["Doc","Grumpy","Happy","Sleepy","Bashful","Sneezy","Dopey"]
for aName in names {
if aName == name {
return name
}
}
return nil
}
if let person = search("Doc") {
println("I found \(person)")
}

7,670 PointsHopefully this below may help you out as a general outline:
1) The function returns "n" in the array "names" because that is really the value we want. You probably want to return "aName" in your example instead of "name" because you are wanting to return the value in the array you searched for.
2) When I went to look at the instructions, it asked to label store the function in a constant called "result."
3) When I went to look at the instructions, it asked to println("Found").
func search(#name: String) -> String? {
let names = ["Doc","Grumpy","Happy","Sleepy","Bashful","Sneezy","Dopey"]
for n in names {
if n == name {
return n
}
}
return nil
}
if let result = search(name: "Doc") {
println("Found")
}
I'm still learning too so I'm sure I have room for improvements in my code as well but the course said this was okay!
