Xcode 16 build warning

I encountered an issue when implementing the WKUIDelegate protocol and NSItemProviderWriting protocol. Below is a minimal example of the code that reproduces the issue:

import UIKit
import WebKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }
}

class ItemProvider: NSObject, NSItemProviderWriting {
    static var writableTypeIdentifiersForItemProvider: [String] {
        fatalError()
    }

    func loadData(
        withTypeIdentifier typeIdentifier: String,
        forItemProviderCompletionHandler completionHandler: @escaping @Sendable (Data?, (any Error)?) -> Void
    ) -> Progress? {
        fatalError()
    }
}

extension ViewController: WKUIDelegate {
    func webView(
        _ webView: WKWebView,
        runJavaScriptAlertPanelWithMessage message: String,
        initiatedByFrame frame: WKFrameInfo,
        completionHandler: @escaping @MainActor @Sendable () -> Void
    ) {
        fatalError()
    }
}

When implementing the WKUIDelegate protocol after NSItemProviderWriting protocol, the following warning appears:

Instance method 'webView(_:runJavaScriptAlertPanelWithMessage:initiatedByFrame:completionHandler:)' nearly matches optional requirement 'webView(_:runJavaScriptAlertPanelWithMessage:initiatedByFrame:completionHandler:)' of protocol 'WKUIDelegate'

The target's SWIFT_VERSION is 6.0.
