This _OBJC_CLASS_$_ Error comes if you dont include the framework for that corresponding Object class. In your case this CheckmarkTile.

If you have included this calendar component in your project. Then rightclick frameworks group in xcode add Existing Frameworks. The Select AddOther and include the build file of that calendar project. Now Clean Build and run.

Or Just try this

Just include the ChemarkTile .h and .m files into your project and then clean build

Make sure it's added to your target to compile. As stated above...

Just include the ChemarkTile .h and .m files into your project and then clean build
