从技术上讲，当我认识的某个人需要 Swift 中的实现时，他使用以下 Objective-C 实现来获取连接的 NSURLCredential 对象； based on the private key and X509 Certificate pair contained in a PKCS12 keystore.
抱歉，我无法使用 Swift 解决方案访问源代码。我所知道的是 NSURLCredential 已返回给 Swift，并直接用于那里的 http url 连接。不过，它与此类似。
我不是 iOS 开发人员，因此无法在“桥接到 Swift”部分为您提供帮助。

无论如何，要使用上面的内容，你只需要从 Swift 中访问它。
func connection(connection: NSURLConnection, willSendRequestForAuthenticationChallenge challenge: NSURLAuthenticationChallenge) {
if let p12Data = UserManager.currentP12,
let credential = CertificateManager.getCredentialsForP12(p12Data) as? NSURLCredential {
challenge.sender.useCredential(credential, forAuthenticationChallenge: challenge)
} else {
UIApplication.sharedApplication().networkActivityIndicatorVisible = false
}
}
使用这个。

CFDictionaryRef optionsDictionary = CFDictionaryCreate(NULL, keys, values, 1, NULL, NULL);
CFArrayRef p12Items;
OSStatus result = SecPKCS12Import((__bridge CFDataRef) p12data, optionsDictionary, &p12Items);
if (result == noErr) {
CFDictionaryRef identityDict = CFArrayGetValueAtIndex(p12Items, 0);

SecCertificateRef certRef;
SecIdentityCopyCertificate(identityApp, &certRef);

编辑：上面有一个 swift 版本，虽然它很混乱，我们宁愿不使用它。
