Cocoapods : ld: library not found for -lBolts
<p>I am using cocoapods in one of my projects and after I cleaned the derived data for my project I have started seeing this error</p>

<pre><code>ld: warning: directory not found for option '-L/Users/vishal/Library/Developer/Xcode/DerivedData/SensorLab-ctzyiyrpdclyjybpujriezgkckkn/Build/Products/Debug-iphoneos/Bolts'

<p>When I open up the <em>Debug-iphoneos</em> from <em>Window > Projects</em> I do not see any folders in there now. Since this problem started cropping up after cleaning derived data I do not really know what did I do which stopped generating those folders.</p>

<p>This is how it looks :

<p>This is kind of how it should look, I imagine (From a different project)

<p>I have tried what was suggested here</p>

<p><a href="https://stackoverflow.com/questions/24078597/cocoapods-ld-library-not-found-for-lpods-projectname">Cocoapods ld: library not found for -lPods-Projectname</a></p>

<p><a href="https://stackoverflow.com/questions/32768516/cocoapods-ld-library-not-found-for-lpods-objectivesugar">Cocoapods ld: library not found for -lPods-ObjectiveSugar</a></p>

<p>And a couple more things which I have tried but to no avail, I have faced my fair share of cocoapod niggles. This seems beyond me.</p>

<p>EDIT: I have been doing some more tests with this, I realized that my pods are not even building ! When I clear derived data for any other project, it goes ahead and builds the Pods next time I try to build the project, but not in this project. What setting can wrong ?</p>

<p>This is how the project looks right now :

<p>Any help will be appreciated.</p>
