Answer 1

Why are you not satisfied with the function-

func filter(_ isIncluded: (Self.Element) throws -> Bool) rethrows -> [Self.Element]

Here is an example of usage. words.filter { word in return word.count >= 3 }
Or do you have a question about how to find a character in a string? - then use this string object function -func contains(_ element: Character) -> Bool
