# samePosition(in:) Returns the position in the given view of Unicode scalars that corresponds exactly to this index. ``` func samePosition(in unicodeScalars: String.UnicodeScalarView) -> String.UnicodeScalarIndex? ``` ## Parameters `unicodeScalars` The view to use for the index conversion. This index must be a valid index of at least one view of the string shared by `unicodeScalars`. ## Return Value The position in `unicodeScalars` that corresponds exactly to this index. If this index does not have an exact corresponding position in `unicodeScalars`, this method returns `nil`. For example, an attempt to convert the position of a UTF-16 trailing surrogate returns `nil`. ## Discussion This index must be a valid index of `String(unicodeScalars).utf16`. This example first finds the position of a space (UTF-16 code point `32`) in a string’s `utf16` view and then uses this method to find the same position in the string’s `unicodeScalars` view. ``` let cafe = "Café 🍵" let i = cafe.utf16.firstIndex(of: 32)! let j = i.samePosition(in: cafe.unicodeScalars)! print(String(cafe.unicodeScalars[..
