Your problem should be fixed by setting the required summary property.

The bug appears to be in the way CocoaPods handles validation - namely in the case where the description field is set, but not summary, as it tries to compare the description and summaries lengths, but does not check for a nil summary.

I'm not completely sure as to how we should fix this. Maybe by bailing out early when props are missing?

Thanks for being great, @dantoml 🙌
