Some Example files have target membership for the StripeiOS and iOSTest targets

[brianwgibson]

Most users won't encounter duplicate symbols, however, it can happen. It triggered for me for MBProgressHud.m which was a dependency of a different library.

Error messages will appear similar to this:
duplicate symbol OBJC_METACLASS$_MBRoundProgressView in:

The fix is to uncheck those targets from each file.

You may need to update the podspec file as well. Something similar to

spec.exclude_files = "Example"

Fixed! Thanks for the report.
