I read the Components Not Used in iOS Apps post in the Embarcadero DocWiki and was unable to tell if ClientDataSets and DataSources can be used in iOS applications. Can anyone confim or deny whether these components will work in iOS applications.
Yes, both ClientDataSet and DataSetProvider can be used in iOS applications. The above answer is incorrect, regarding the Data and Datasnap namespaces. These units are cross-platform. You can see this if you pause your cursor over either ClientDataSet or DataSetProvider in the Tool Palette. Doing this displays the OSs supported by the component you are pausing over, and display for both of these components includes both iOS and Android.
