Since the Quartz Beta 2 release I've been unable set up new projects using the ArcGIS Runtime using CocoaPods. When running Pod Install or Pod Update I get an error like this:
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
Figured this out - it is our helpful corporate blockpage interfering because ESRI hosts the pod file in their box account and our company likes to remind us that they don't really approve of cloud storage.
Carry on.
