认证提供程序请求失败，错误为：在路径“Provider/attributes/developerTeamId”处出现意外的空属性。

这个错误通常与证书签名身份验证有关。可能的解决方法是确保你的账户和访问令牌在您的计算机上是正确的，并且您的证书和私钥都是有效的。

您还可以尝试使用下面的代码示例，将证书和私钥导入到你的密钥链中，以便在代码中访问它们：

import Foundation
import Security

func importCertificate(from file: String, password: String) -> (certificate: SecCertificate?, key: SecKey?) {
    guard let certificateData = NSData(contentsOfFile: file) else {
        print("Certificate file not found")
        return (nil, nil)
    }

    let options: NSDictionary = [kSecImportExportPassphrase: password]

    var rawItems: CFArray?
    let status = SecPKCS12Import(certificateData, options, &rawItems)

    guard status == errSecSuccess else {
        print("Unable to import certificate. Error \(status).")
        return (nil, nil)
    }

    let items: Array = rawItems as Array

    guard let identityDict = items.first as? NSDictionary,
          let identityRef = identityDict[kSecImportItemIdentity as String],
          let identity = identityRef as? SecIdentity,
          let certificate = SecCertificateCopyCertificateChain(identity),
          let key = SecIdentityCopyPrivateKey(identity)
    else {
        print("Unable to extract identity and certificate.")
        return (nil, nil)
    }

    return (certificate, key)
}

可以将这个函数与以下代码结合使用，从而创建一个NSURLSessionConfiguration实例，并在认证提供者请求中使用它：

let (certificate, key) = importCertificate(from: path, password: password)

guard let identity = key else {
    print("Unable to authenticate. Private key not found.")
    return
}

let credential = URLCredential(identity: identity, certificates: [certificate], persistence: .forSession)

let configuration = URLSessionConfiguration.default
configuration.urlCredentialStorage.set(credential,
