Building Mac Farm: Running 2000+ iOS Pipelines Daily

At Trendyol, they run over 2,000 iOS pipelines daily across 130 Mac machines, executing 50,000+ unit tests and 10,000+ UI tests for their iOS apps. The team initiated a mobile CI transformation to address the challenges of scale and performance as their team grew and AI usage increased. They built a macOS farm from scratch with a system topology consisting of critical layers including the Host Agent, VM Agent, User Terminal, and Server. They also optimized their GitLab CI pipelines by creating common pipelines for all repositories and implementing a log structure without unnecessary parts.
