Introduction

Challenges of mobile frontend development

• Stories with multiple requirements.
• Multiple stakeholders (backend devs, designers, QAs, PMs, SMs, Testers, CTO, CEO ….).
• Multiple environments, configurations.
• Working on multiple features in parallel.
• Demonstrating multiple states for UI components.
• Mobile app deployment is complicated.
• Continuous delivery.

Scenario-driven development

• Scenarios is a system supporting continuously delivering of incremental updates for mobile app frontends.
• Targeting early feedback loop from all stakeholders.
• Avoiding the need to deliver multiple apps for different purposes.
• Easing parallelism between feature teams.
• Supporting automated tests.
• Extensible, new types of scenarios can be created to accommodate different stakeholders: prototype scenario, design system scenario, accessibility scenario, etc ...

Recommended modular architecture

Sample app

There is a sample app inside this repository. The app fetches the list of popular Swift repositories from Github and display them in a UITableView.

The app will contain all scenarios for each of the components, as well as a mocking and a production environment scenarios.
