如何排序 AVSpeechSynthesisVoice.speechVoices()

Question

我是一个初学者，我正在做这个，我注意到选择器视图没有排序

土耳其语之后显然没有中文，那我该如何整理呢？我一直在查看我的代码几个小时，似乎无法弄清楚如何对其进行排序。这是我的完整代码。

谢谢

import AVFoundation
import UIKit

class SettingsView: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource {
    @IBOutlet var pickerView: UIPickerView!

    var voicesArray: [String] = []
    let speechVoices = AVSpeechSynthesisVoice.speechVoices()

    override func viewDidLoad() {
        super.viewDidLoad()

        pickerView.delegate = self
        pickerView.dataSource = self
    }

    func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 1
    }

    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        return speechVoices.count
    }

    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        let language = Locale.current.localizedString(forLanguageCode: speechVoices[row].language)!
        let languageCode = speechVoices[row].language

        var regionCode:String = ""
        for region in Locale.isoRegionCodes {
            // Test if provided region codes has voices or not
            if languageCode.contains(region) {
                regionCode = region
            }
        }

        let country = Locale.current.localizedString(forRegionCode: String(regionCode))

        return "\(language) (\(country ?? ""))"
    }

    @IBAction func done(_ sender: UIButton) {
        dismiss(animated: true, completion: nil)
    }
}

中文 (zh) 肯定排在土耳其 (tr) 之后，所以这些似乎已经按地区代码排序。如果您想按其他内容进行排序（我假设它们的显示名称以区域设置语言显示），那么您可以在为选择器设置元素列表时对它们进行排序。例如：

let speechVoices = AVSpeechSynthesisVoice.speechVoices().sorted(by: {
    Locale.current.localizedString(forLanguageCode: $0.language)! < Locale.current.localizedString(forLanguageCode: $1.language)!
})
