Sometimes we find that Xcode likes to hang on to old frameworks so you might be unwittingly using the trial version of Shinobi.
To solve this you can try moving the charting component to somewhere else on disk and reference it from there, as all of XCodes’ reference caches are based on paths.
Also you can check which version the app thinks it is running by calling [chart getInfo]. That would be the definitive evidence as to which version Xcode has picked up.
If this doesn't solve the problem, do let me know.
