12. App Startup Time • Do less! • Embed fewer dylibs • Declare classes/methods • Use fewer initializers • Use more Swift • No initializers • Swift size improvements
13. Monitoring • In Development • Use DYLD_PRINT_STATISTICS • Initializer Calls • After Release • Firebase Performance Monitoring How to
14. Initializer Calls • Available on iOS 11 and macOS High Sierra • Provides precise timing for each static initializer • Available through Instruments
