[nuclide-swift] Autocomplete doesn't show all properties and methods after the "."(dot) symbol

Issue and Steps to Reproduce

Autocomplete doesn't show instance properties/methods until I start typing letters after the dot

Expected Behavior

Autocomplete should show all possible completions after the dot symbol

For example

struct Foo {
    let baz: String = ""
    let bar: String = ""

    func exmp() {

    }
}

let x = Foo()
x. // Should show baz, bar, exmp - doesn't show anything until I type a letter

Actual Behavior

Nothing is shown until I start typing the first letters of the property/method name
