I could not run spark-setup-ios-example from this link with cocoapods-keys plugin. It is given me cocoapods-keys plugin error when I do Pod Install/Update even after the successful gem installation of the plug in. Any suggestion or help is appreciated.

@mtun009, I was able to get this example working I followed @ido comments; please reference his post.
btw: my podfile only have:

pod “SparkSetup”

I hope this helps.
