以编程方式检测我的iPhone设置中设置的所有键盘？

import UIKit

func getAllKeyboards() -> [String] {
    var keyboards: [String] = []
    
    if let keyboardsSettingsURL = URL(string: "App-Prefs:root=General&path=Keyboard/KEYBOARDS") {
        if UIApplication.shared.canOpenURL(keyboardsSettingsURL) {
            UIApplication.shared.open(keyboardsSettingsURL, options: [:], completionHandler: nil)
        }
    }
    
    if let keyboards = UserDefaults.standard.dictionaryRepresentation()["AppleKeyboards"] as? [String] {
        for keyboard in keyboards {
            keyboards.append(keyboard)
        }
    }
    
    return keyboards
}

let allKeyboards = getAllKeyboards()
print(allKeyboards)
