Answer 1

这是 errSecParam,表明您的一个或多个参数是错误的.

Answer 2

如果要向钥匙串添加密码，请确保将其作为数据而不是字符串传递，否则将收到OSStatus错误-50。

static func savePassword(password: Data, account: String) throws -> OSStatus {
    let query = [
        kSecClass as String: kSecClassGenericPassword as String,
        kSecAttrAccount as String: account,
        kSecValueData as String: password
        ] as [String: Any]

    SecItemDelete(query as CFDictionary)

    return SecItemAdd(query as CFDictionary, nil)
}
