在pod安装后，Alamofire会出现错误

I know that there is many questions about that but I can't find a solution for that. I use Xcode 8 and swift 2.3. When I add Alamofire in my application the build always fails and it gives me error in relation with the swift version. If anyone was facing the same issue and fixed it please give me the solution for than or advice me about the right way to use Alamofire without errors (it's the first time that I will use it and I'm really new to ios devlopement)I know that there is many questions about that
