Discussion

For example, this code sample finds the indices of all the vowel characters in the string, and then removes those characters.

var str = "The rain in Spain stays mainly in the plain."
let vowels: Set<Character> = ["a", "e", "i", "o", "u"]
let vowelIndices = str.indices(where: { vowels.contains($0) })

str.removeSubranges(vowelIndices)
// str == "Th rn n Spn stys mnly n th pln."
