如何排序 AVSpeechSynthesisVoice.speechVoices()

Question

我是初学者，在处理此问题时，我注意到选择器视图未排序

很明显汉语没有排在土耳其语之后，那我该如何排序呢？几个小时以来，我一直在查看我的代码，但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，因此这些似乎已按区域代码排序。如果您想按其他方式排序（我假设它们在语言环境中的显示名称），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: [=10=].language)! < Locale.current.localizedString(forLanguageCode: .language)!
})
