Testing iOS 12 Beta
Article Summary
Kateryna Sprynsian from Bumble Tech shares a hard truth: when iOS 12 launched, 60% of their users updated within 8 weeks. Were they ready? Here's how they avoided disaster.

Key Takeaways
- Started testing at beta 6, not beta 1—early betas too unstable
- Tested with both old Xcode 9 and new Xcode 10 builds
- Found crashes on launch, freezes, duplicate permissions, broken layouts
- CPU, memory, and battery usage showed no significant impact vs iOS 11
- Included iOS 12 checks in every feature, integration, and release test
Critical Insight
