Prototype & Design App Store Ready App In Interface Builder • Jake Lin • YOW! 2016

Interface Builder combined with IBAnimatable library allows designing App Store-ready apps without writing code, supporting animations, transitions, and interactions

Protocol-oriented programming (POP) enables encapsulating UI logic in reusable protocols rather than subclasses, making components more flexible and maintainable

IBAnimatable provides 200+ pre-built animations, transitions, and UI effects that can be configured directly in Interface Builder through inspectable properties

Auto Layout and adaptive layouts in Interface Builder allow designing responsive interfaces that work across multiple iOS devices from a single design

Color spaces and RGB values can differ between design tools (Sketch) and Xcode/Interface Builder, requiring careful attention when implementing designs

Gesture support enables adding interactive navigation and transitions between screens without writing code

Material Design and other UI patterns can be implemented through IBAnimatable’s pre-built components and properties

Designers can work directly in Interface Builder to iterate on designs and see changes instantly without needing to write code or recompile

Protocol extensions allow providing default implementations while keeping APIs simple and allowing platform-specific customization

Interface Builder combined with IBAnimatable reduces the gap between design and development by providing a shared tool both roles can use effectively
