Summary:
When using a function that takes a closure as one argument, autocomplete always uses the most verbose declaration of the closure although shorter versions are more readable and valid

Steps to Reproduce:
1. Create a Swift function like the following:
func executeClosure(closure: ()->Void) {
	closure()
}

2. Use this function by typing executeClo and autocompleting it to executeClosure(<#closure: () -> ()##() -> ()#>)
3. Autocomplete the closure bubble

Expected Results:
This should result in code like this:
executeClosure {
	<#code#>
}

Actual Results:
Xcode expands to a fully specified version of the closure that is less legible
executeClosure { () -> Void in
	<#code#>
}

Version:
Xcode 6.0 (6A280e)
