检查iOS swift中的Javascript库版本

import WebKit

// 创建一个WKWebView实例
let webView = WKWebView(frame: CGRect(x: 0, y: 0, width: 320, height: 480))

// 加载JavaScript库
if let url = Bundle.main.url(forResource: "your_javascript_library", withExtension: "js") {
    do {
        let javascript = try String(contentsOf: url)
        let userScript = WKUserScript(source: javascript, injectionTime: .atDocumentStart, forMainFrameOnly: true)
        let userContentController = WKUserContentController()
        userContentController.addUserScript(userScript)
        let configuration = WKWebViewConfiguration()
        configuration.userContentController = userContentController
        webView.configuration = configuration
    } catch {
        print("Failed to load JavaScript library: \(error)")
    }
}

// 在webView中执行JavaScript代码
webView.evaluateJavaScript("your_javascript_library.version") { (result, error) in
    if let error = error {
        print("Failed to evaluate JavaScript: \(error)")
    } else if let version = result as? String {
        print("JavaScript library version: \(version)")
    }
}
