Mobile SDK Modernization for Woopra
Woopra, a leading customer analytics platform, needed to modernize their aging iOS SDK to keep pace with Apple's evolving ecosystem and developer expectations. Our team successfully rebuilt their mobile SDK from the ground up, migrating from legacy Objective-C to modern Swift.
Key Results
What We Were Up Against
Woopra's SDK was built in Objective-C, which was becoming outdated as Swift gained dominance in iOS development. Modern iOS developers preferred Swift-based libraries, limiting the SDK's appeal and increasing maintenance costs.
Key Pain Points
- 1Legacy Objective-C codebase becoming outdated
- 2Modern iOS developers preferred Swift-based libraries
- 3Updating and maintaining Objective-C code was increasingly difficult
- 4Legacy implementation didn't take advantage of Swift's performance optimizations
- 5Existing documentation was outdated and incomplete
How We Solved It
We implemented a phased, agile development approach to minimize risk and ensure quality. The new SDK leveraged Swift's protocol-oriented programming for extensibility and maintainability.
Our Approach
- 1Phase 1: MVP with core functionality (2-4 weeks)
- 2Phase 2: Feature completion with advanced analytics (2-3 weeks)
- 3Phase 3: Polish, optimization, and migration guides (1-2 weeks)
- 4Deep requirements analysis of existing SDK functionality
- 5Architecture design using protocol-oriented programming
Key Features Built
- Event tracking with custom properties
- Flexible user identity management
- Queue-based offline tracking with automatic sync
- Comprehensive error handling and logging
- Optimized for minimal battery and network impact
- Thread-safe concurrent operations using dispatch queues
