I am using the Xcode 8.0 GM. I created a default single-view app with my deployment target set to 9.0.
In my Podfile I\'m targeting the bleeding edge Swift 3 branch:
The solution is to change your request from this
pod 'Alamofire', :git => 'https://github.com/Alamofire/Alamofire.git', :branch => 'swift3'
to this
pod 'Alamofire', :git => 'https://github.com/Alamofire/Alamofire.git', :branch => 'master'
