Question

我想从字符串中将所有字母都放入数组中。假设我有包含字母和数字的字符串，那么我只想获得字符串的所有字母。

let myString = "so123han"

然后输出应该是这样的数组：

let arrayOfLetters = ["s","o","h","a","n"]

let myString = "so123han"
let alphaChars = myString.unicodeScalars.filter({ CharacterSet.letters.contains($0) }).map({ Character($0) })

let myString = "so123han"
var arr = [String]()

    if CharacterSet.letters.contains(i){
        arr.append("\(i)")
    }
}
