        NSHTTPCookieValue: Constants.deviceId

    let cookiePropertiesVersion = [
        NSHTTPCookieOriginURL: Constants.baseUrl,
        NSHTTPCookiePath: "/",
        NSHTTPCookieName: "app_version_code",
        NSHTTPCookieValue: "50"

    let newCookie = NSHTTPCookie(properties: cookieProperties)
    let newCookieVersion = NSHTTPCookie(properties: cookiePropertiesVersion)
    cookieStorage.setCookie(newCookie!)
    cookieStorage.setCookie(newCookieVersion!)

试试这个代码。这可能会对您有所帮助。发生这种情况是因为NSHTTPCookie(properties: cookieProperties)is 返回 nil as ，newCookie并且您正在尝试设置nil。cookieStorage

   if let newCookie = NSHTTPCookie(properties: cookieProperties){
        cookieStorage.setCookie(newCookie!)
    }
    let newCookieVersion = NSHTTPCookie(properties: cookiePropertiesVersion)
