Human Interface Design
It’s not enough to create an app that works. Users expect iOS apps to be intuitive, interactive, and engaging. Think about the user experience as you design every aspect of your app, from the features you choose to the way your app responds to a gesture.
Although users might not be aware of human interface design principles, they can tell when apps follow the guidelines and when they don't. Follow the principles and conventions spelled out in iOS Human Interface Guidelines to design a superlative user interface and user experience for your product.
