4D for iOS is an integrated 4D component that allows you to configure, design, test, and build a native iOS app based on your 4D database. 4D handles the complexity and generates - in a totally transparent way - an Xcode project in pure Swift with an optimized UI/UX.

4D for iOS main features include:

• a project designer directly available from 4D,
• an extensive simulator to test your app on different devices
• offline mode support (embedded data)
• data synchronization
• generation of a real Xcode project, that can be customized afterwards
• ability to create an unlimited number of apps from the same 4D database
