Hello Apple Team, I’ll be attending the Battery and Performance Optimization Lab this Thursday, and I’d like to prepare as thoroughly as possible to get the most value from the session. I’m particularly interested in understanding what I can do beforehand to identify optimization opportunities in my app and arrive with useful performance measurements and actionable questions. I would appreciate your guidance on a few areas: Xcode configuration: Are there specific build settings, diagnostic options, profiling configurations, or performance-related settings I should enable or review before the lab? Performance measurement: Which Instruments templates, metrics, or profiling workflows would you recommend using beforehand to establish a meaningful baseline for CPU usage, memory, energy consumption, and battery efficiency? Preparation: What measurements, diagnostic reports, or reproducible test scenarios would be most useful to bring so we can spend more time investigating optimization opportuniti
