如何停止JavaScriptCore JSContext在iOS上强制求值？

let currentContext = JSContext.current()

let script = "your JavaScript code"
let timeout = 5 // 设置超时时间，单位为秒

let result = currentContext?.evaluateScript(script)
let timer = Timer.scheduledTimer(withTimeInterval: TimeInterval(timeout), repeats: false) { _ in
    currentContext?.exception = JSValue(newErrorFromMessage: "Evaluation timeout", in: currentContext)
    currentContext?.virtualMachine?.terminateExecution()
}

RunLoop.current.run()

timer.invalidate()

if let exception = currentContext?.exception {
    print("Evaluation timeout: \(exception)")
} else {
    print("Evaluation completed successfully")
}
