What do engineering-driven companies like Spotify, Snapchat, and Block (formerly Square) have in common?
They don’t simply follow established “best practices.” Instead, they define their own architecture, tooling, and internal frameworks tailored to their specific domain and vision.
Which demands a deep understanding of both the project's environment as well as the core principles of building high-quality software.
This project was built to showcase how to move fast without sacrificing quality. It strikes the balance between lightwight simplicity and scalable structure.
The aim wasn’t trying to build the "perfect" architecture; it was to build a system that supports the attributes I care about most:
Above all, simplicity.
Simple systems are easier to understand and maintain, and harder to misuse.
As systems have the tendency to grow in complexity over time, simplicity is constantly at risk. But if maintained, it brings joy and confidence to the development.
The foundation for a flexible system.
Small, loosley coupled parts working togehter greatly increase the chances of extensibility and reusabilty.
Cohesion is what makes a project one thing.
Consistency across the codebase reduces the overall cognitive load which makes working on it more comfortable and easier.
Because we value speed and quality.
The ability of the codebase to scale in complexity and contributors without reducing throughput.
Each decision in this template has been made to optimize for the principles outlined above.
This is not a framework you plug and play — it’s a foundation to think from, adapt, and extend.
In-house Dependencies:
- SwiftDependencyContainer Code generation-powered depdency management
- SwiftCopy Convenient copy functionality for immutable structs to ensure thread safety
- SwiftUDF Binding SwiftUI views with a uni-directional data flow architecture
- SwiftEvolution Set of useful Swift extensions
Checkout the Template.xcodeproj, enable the compiler build plugins and run to see the project in action.
This project is an invitation to explore engineering principles together — not just to implement them, but to think critically about how they apply to your project, your constraints, and your future.
