error while running iOS simulator

[DCC Fatal Error] Unit2.pas(9): F2051 Unit Sparkle.Mac.HttpEngine was compiled with a different version of Macapi.ObjectiveC.TOCGenericImport`2.GetOCClass

what can I do to get it working?
or what am i doing wrong.

I believe this is a trial version? If yes, then use Release config instead of Debug config. The binaries are incompatible, unfortunately, and trial version only offers Release binaries to reduce file size.

thanks, that worked for me.
