What Feature Team Structure Has Changed for iOS Team at leboncoin
Article Summary
Amandine Cousin from leboncoin reveals how their iOS team of 9 developers ships features continuously on a single branch. No release branches, no merge chaos, just one button deploys.
When leboncoin reorganized from siloed teams to cross-functional feature teams, their iOS developers faced a challenge: how do 9 people work on the same codebase without constant conflicts? They rebuilt their entire development workflow around modular architecture and feature toggles.
Key Takeaways
- Split monolithic app into 8 independent modules plus main app
- Single branch workflow with feature toggles replaces complex branching
- Automated CI pipeline tests all dependent modules on every commit
- Progressive rollout starts at 1% of users after Apple approval
- One button deployment replaced multi-branch process requiring 2 specialists
leboncoin's iOS team can now ship features anytime with 9 developers working simultaneously on one branch, all while serving 1 million daily active users.
About This Article
When 9 developers worked on leboncoin's iOS app at the same time, they kept running into merge conflicts and dependency issues. The codebase was one big monolith with no clear structure to separate different parts of the work.
The team split the app into 8 independent modules: 4 for features and 4 for technical infrastructure. They used Carthage frameworks to build these modules, then set up Jenkins to automatically compile and package shared versions through shell scripts.
The modular setup fixed a real problem. Before, only 1 or 2 people knew how to handle a release. Now any developer can deploy the app by clicking a button instead of manually juggling multiple branches.
