我存档项目时遇到了这个问题。当我在模拟器上运行应用时，没有上面的问题，一切正常。
I got this issue when I Archive my project. When I run app on simulator it works ok without such issue above.
此外，它在 Xcode 8 下也可以正常工作，但是现在，当我尝试将其存档在 Xcode 9 上时，我遇到了这个问题。但是也许情况并非如此，因为我从头开始重新安装了 Mac OS ，所以我不确定那是cocopods版本的问题。
Also it works ok with Xcode 8, but now when I try to Archive it on Xcode 9 I have this issue. But maybe this is not the case as I reinstall Mac OS from scratch, so it maybe cocopods version issue I am not sure.
在上面的示例中还有两个 // 对我来说也很奇怪 /Applications//MyProject.app
Also two // here in the example above is also strange for me /Applications//MyProject.app
我认为这是Xcode的错误。重新启动Mac，然后尝试重新构建。 Xcode会在构建Alamofire之前要求获得访问您的钥匙串的许可，然后才允许它。
I believe it's a Xcode's bug. Restart your Mac and try to build again. Xcode would ask permission to access your Keychain before build Alamofire, then just allow it.
