iOS continues to evolve and we’re constantly looking to improve our code while providing rich user experiences.  Here’s a few ideas people have had that continue to push the envelope in architectural design patterns.

• VIPER – Designed for testability
• SOLID principles – some guidelines on how to separate the components of your code
• ReSwift (based on REDUX) – Attempts to more clearly separate state vs actions
• MVVM – Model — View — View-Model
• CORE – Brings state machines
• 4v Engine – An enhancement over VIPER and MVVM-C
