如何在 Mac 上的 Mac Catalyst 应用程序中使用钥匙串？

Question

我无法在 Mac 上的 Mac-Catalyst 应用程序中从钥匙串 write/read，它分别 returns 错误 34018 和 25300。有没有办法让钥匙串在 Catalyst 应用程序的 Mac 上工作？

Xcode: 11.0, MacOS: 10.15

这是一个示例代码，它适用于 iOS 但不适用于 Mac。代码打印 "My secretive bee " 表示我们已成功将此文本写入钥匙串，然后从中读取。

override func viewDidLoad() {
  super.viewDidLoad()

  let itemKey = "My key"
  let itemValue = "My secretive bee "
  deleteFromKeychain(itemKey: itemKey)
  addToKeychain(itemKey: itemKey, itemValue: itemValue)
  readFromKeychain(itemKey: itemKey)
}

func deleteFromKeychain(itemKey: String) {
  let queryDelete: [String: AnyObject] = [
    kSecClass as String: kSecClassGenericPassword,
    kSecAttrAccount as String: itemKey as AnyObject,
  ]

  let resultCodeDelete = SecItemDelete(queryDelete as CFDictionary)

  if resultCodeDelete != noErr {
    print("Error deleting from Keychain: \(resultCodeDelete)")
  }
}

func addToKeychain(itemKey: String, itemValue: String) {
  guard let valueData = itemValue.data(using: String.Encoding.utf8) else {
    print("Error saving text to Keychain")
    return
  }

  let queryAdd: [String: AnyObject] = [
    kSecClass as String: kSecClassGenericPassword,
    kSecAttrAccount as String: itemKey as AnyObject,
    kSecValueData as String: valueData as AnyObject,
    kSecAttrAccessible as String: kSecAttrAccessibleWhenUnlocked,
  ]

  let resultCode = SecItemAdd(queryAdd as CFDictionary, nil)

  if resultCode != noErr {
    print("Error saving to Keychain: \(resultCode)")
  }
}

func readFromKeychain(itemKey: String) {
  let queryLoad: [String: AnyObject] = [
    kSecClass as String: kSecClassGenericPassword,
    kSecAttrAccount as String: itemKey as AnyObject,
    kSecReturnData as String: kCFBooleanTrue,
    kSecMatchLimit as String: kSecMatchLimitOne,
  ]

  var result: AnyObject?

  let resultCodeLoad = withUnsafeMutablePointer(to: &result) {
    SecItemCopyMatching(queryLoad as CFDictionary, UnsafeMutablePointer([=12=]))
  }

  if resultCodeLoad == noErr {
    if let result = result as? Data,
      let keyValue = NSString(data: result,
                             encoding: String.Encoding.utf8.rawValue) as? String {

      // Found successfully
      print(keyValue)
    }
  } else {
    print("Error loading from Keychain: \(resultCodeLoad)")
  }
}

我在 xcode 的签名和功能部分启用了钥匙串共享，现在我可以在钥匙串中存储值。
