How do I pass Challenge Task 2 on optionals?

Question

I've asked for help on this before but the code recommended didn't work.  I tried: if let result = search(name:"Doc").  When I placed this code in I got this error... 
swift_lint.swift:15:39: error: expected '{' after 'if' condition
    if let result = search(name:"Doc") 
What am I doing wrong and what is the right code?
```search.swift
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") 
}
```

There are two issues here, first the last line of the method (if let statement) is incomplete, you must add a pair of curly braces {} to complete the block. Second even when you fixed that, there is still a logic error, because you try to use the function within the function. The solution is to get rid of the if let statement and put it outside the function.
```
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(result)
}
```
