swift 从阿拉伯语中删除变音符号

Question

我正在尝试删除阿拉伯语文本变音符号。例如，我需要将此 َ 转换为此 ب ，这是我的代码:

if (text != "") {
    for char in text! {
        print(char)
        print(char.unicodeScalars.first?.value)
        if allowed.contains("\(char)"){
            newText.append(char)
        }
    }
    self.textView.text = text!
} else {
//            TODO :
//            show an alert
    print("uhhh no way")
}

我已经尝试过这些解决方案但没有成功:

你可以使用正则表达式，试试这段代码

 let myString = "الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ"
        let regex = try! NSRegularExpression(pattern: "[\\u064b-\\u064f\\u0650-\\u0652]", options: NSRegularExpression.Options.caseInsensitive)
        let range = NSMakeRange(0, myString.unicodeScalars.count)
        let modString = regex.stringByReplacingMatches(in: myString, options: [], range: range, withTemplate: "")
        print(modString)

Output : الحمد لله رب العالمين
