What is CocoaPods "(unused)" - ios

Question

After running pod outdated, I get the following output
Updating spec repo `master`
Analyzing dependencies
The following pod updates are available:
- AFNetworking 2.4.4 -> 2.5.4 (latest version 3.0.0-beta.2)
- HexColors 2.2.1 -> 2.2.1 (latest version 3.0.0)
- Overcoat 3.0.0 -> (unused) (latest version 3.2.1)
- ReactiveCocoa 2.5 -> 2.5 (latest version 4.0.4-alpha-4)
I have not seen this "unused" term before
i.e.
Overcoat 3.0.0 ->(unused) (latest version 3.2.1)
What is this? And what does it mean?

Answer 1

After analyzing the source code, I think that (unused) means that the Pod is not in your Podfile (probably you removed it and didn't reinstall)
AFNetworking 2.4.4 -> 2.5.4 (latest version 3.0.0-beta.2)
^ ^ ^ ^
Pod name Installed version Podfile version Latest

Answer 2

Based on the source code which inserts this tag, which looks like this:
if source_version > lockfile_version
matching_spec = unlocked_pods.find { |s| s.name == pod_name }
matching_version =
matching_spec ? matching_spec.version : '(unused)'
[pod_name, lockfile_version, matching_version, source_version]
end
It appears that this simply means that CocoaPods could not find that Pod within your 'unlocked pods'.
I don't speak Ruby well enough to determine exactly what an "unlocked" pod is (nor am I familiar enough with CocoaPods to have heard the term necessarily... but I am aware of a 'lockfile', and maybe this is related), but here is the source code for determining that:
def unlocked_pods
#unlocked_pods ||= begin
pods = []
UI.titled_section('Analyzing dependencies') do
pods = Installer::Analyzer.new(config.sandbox, config.podfile).
analyze(false).
specs_by_target.values.flatten.uniq
end
pods
end
end
