ios - 快速错误: Classes implemented in two places but files I don't touch?

Question

我正在测试 swifts UIWebView，我在 Storyboard上放置了一个简单的 UIWebview，这是我的 viewController 代码

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var webView: UIWebView!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        let url = URL(string: "https://mywebsitehere.com")
        webView.loadRequest(URLRequest(url: url!))

    } }

不幸的是，我在下面收到此错误，我已将应用程序传输安全设置添加到我的应用程序中，就像类似问题的其他答案所说的那样，但它仍然无法正常工作...

有人可以帮忙吗？

objc[946]: Class PLBuildVersion is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices (0x124feecc0) and /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices (0x124e056f0). One of the two will be used. Which one is undefined.

这是 xCode 在模拟真实 iOS 设备时出现的错误，有时会出现此类错误。请检查您的网址是否有效。

let url = URL(string: "https://google.com")
webView.loadRequest(URLRequest(url: url!)) 

我对 google URL 使用了相同的代码，它正在工作。
