After a production launch regression made startup time reach almost eight seconds for some users, inDrive’s iOS platform team built automated launch performance tests with XCUITests. The system runs nightly on CI, uses real test accounts and production-like flows, sends metrics to internal storage, and alerts engineers in Slack when startup time crosses the threshold. Later, the team added slow-network simulation to catch cache-related regressions that only appear under unstable connections. As a result, launch performance issues are now detected in develop before they reach users
