Axiom Performance

This is your routing layer for anything performance related on iOS. Memory leaks, app hangs, slow launch, battery drain, profiling with Instruments or xctrace. The decision tree is thorough and covers the messy edge cases like distinguishing between a hang and just sluggishness, or knowing when memory pressure is causing your frame drops. It bridges to specialized skills for Swift-specific leaks, Objective-C block cycles, energy auditing, and even timer footguns that cause EXC_BAD_INSTRUCTION. The routing logic is opinionated in a good way, like steering you to hang diagnostics first if the UI is completely frozen versus performance profiling if it's just slow. Solid starting point when users report "the app feels off" and you need to narrow down what to instrument.
