如何将依赖项传递给URLProtocol子类？

import Foundation

class CustomURLProtocol: URLProtocol {
    private var dependency: SomeDependency // 依赖项
    
    init(dependency: SomeDependency) {
        self.dependency = dependency
        super.init()
    }
    
    override class func canInit(with request: URLRequest) -> Bool {
        // 判断是否可以处理该请求
        return true
    }
    
    override class func canonicalRequest(for request: URLRequest) -> URLRequest {
        // 对请求进行修改或添加自定义头部信息等
        return request
    }
    
    override func startLoading() {
        // 进行实际的网络请求，并将结果返回给客户端
        let response = URLResponse(url: self.request.url!, mimeType: nil, expectedContentLength: 0, textEncodingName: nil)
        self.client?.urlProtocol(self, didReceive: response, cacheStoragePolicy: .notAllowed)
        self.client?.urlProtocolDidFinishLoading(self)
    }
    
    override func stopLoading() {
        // 停止加载请求
    }
}

// 在使用URLSession进行网络请求时，将自定义的URLProtocol子类添加到请求中
let configuration = URLSessionConfiguration.default
configuration.protocolClasses = [CustomURLProtocol.self] + (configuration.protocolClasses ?? [])
let session = URLSession(configuration: configuration)
let task = session.dataTask(with: URL(string: "https://example.com")!)
task.resume()
