Xcode 8 swift pod headers empty after pod install
<p>I am trying to compile an existing xcode project written in swift. The project uses Alamofire. I installed xcode 8 beta and opened the project. There were many errors with Alamofire which I learned need to be updated to version 3.2.1. </p>

<p>I edited my Podfile and fixed the version number then ran <code>pod update alamofire</code>. Instead of only updating Alomfire, every pod was updated. This is apparently a bug.</p>

<p>The Podfile contains the directive use_frameworks! After updating the pods, the pods/headers directory was completely empty, without either Public or Private directories and the project failed to build with 356 missing file errors.</p>

<p>Changing the build search settings for ALWAYS_SEARCH_USER_PATHS to no (or yes) in accordance with a recommendation here <a href="https://github.com/CocoaPods/CocoaPods/issues/4605#issuecomment-208822149" rel="nofollow noreferrer">https://github.com/CocoaPods/CocoaPods/issues/4605#issuecomment-208822149</a> then deleting the pods and running pod install again did nothing.</p>

<p>There are a number of different questions on stackoverflow asking the same question with no answers. Here is a list of the ones I can find.</p>

<p>I really need to find a solution to this problem so I would be grateful if anybody can answer this question.</p>
