I'm trying to figure out whether or not I need to specify versions in my Podfile. As far as I can tell, Podfile.lock is doing that for me so I don't see a need to keep the Podfile updated with versions. Am I missing something?
what versions exactly? if you mean the version of the Pods you're installing then you don't need to, because it'll give you the latest one. but if you mean the Platform itself - "iOS version" in this case just type the same as the Deployment Target you've in your project.
