Xcode/Swift 'filename used twice' build error
<p>I'm new to Swift and am struggling with an error after I have (possibly) correctly installed a 3rd party framework via CocoaPods.</p>

<p>The error is as follows.</p>

<pre><code>&lt;unknown&gt;:0: error: filename "MainController.swift" used twice: '/Users/myname/Desktop/ProjectName/ProjectName/Controllers/MainController.swift' and '/Users/myname/Desktop/ProjectName/ProjectName/Controllers/MainController.swift'
&lt;unknown&gt;:0: note: filenames are used to distinguish private declarations with the same name
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1
</code></pre>

<p>As far as I can gather from other forums and seemingly obvious is that I have to remove one of the files being used twice. However I can't see where they would be installed twice. If I remove the file from the /Controllers folder the error becomes 'file not found' etc.</p>

<p>So my question is, where would these conflicting files be located and how do I safely remove one of them? Or is it more that there is only one file but it is being used twice - in which case how do I stop that?</p>

<p>Many thanks.</p>

<p>Ok I feel that comments are getting lost so am clarifying here to see if can trigger an answer as not been able to build and run this since yesterday.</p>

<p>I now have only the swift files in the Pods->Pods/MainController folder.</p>

<p>When I build I get a file not found. However the file it is looking for is in App->Controllers folder which is where I deleted it from. If I put the file in there I get the 'used twice' error.</p>

<p>So how do I stop it trying to find the file in the Controllers and look for it in the Pods?</p>

<p>Thanks</p>
