title: Drop support for Cocoapods for a library
body: <p>I want to drop the support for Cocoapods for a library I'm developing. The library is several years old, so it has a <code>.xcworkspace</code> file, an <code>Example</code> and all the source files are into a <code>Pods</code> folder. It already supports Swift Package Manager and I want to go all in with it. Is there a procedure for this or should it be done manually?</p>
