Courses Plus Student 2,977 PointsThis code works in play ground but does not seem to satisfy the challenge. Please help...
At first I nested the fi let statements, but then I simply added to the existing if let and in the playground it worked. However, I have not satisfied the challenge.
func search(#name: String) -> String? {
let names = ["Doc","Grumpy","Happy","Sleepy","Bashful","Sneezy","Dopey"]
for n in names {
if n == name {
_ = n
println("Found")
return n
}
}
return nil
}
search (name: "Doc")

Your code is correct except that it does not answer the code challenge.
They are looking for something very specific.
See below.
func search(name 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") { // use if let
println("Found") // print "Found" if found
}
I hope that helps,
Mike
