Libraries not found when using CocoaPods with iOS logic tests

Question

CocoaPods 1.0 has changed the syntax for this. It now looks like this:

def shared_pods
    pod 'SSKeychain', '~> 0.1.4'
    ...
end

target 'Sail' do
    shared_pods
end

target 'Sail-iOS' do
    shared_pods
end

Pre CocoaPods 1.0 answer

What you want to use is link_with from your Podfile. Something like:

link_with 'MainTarget', 'MainTargetTests'

Then run pod install again.
