iOS Performance

Performance and tuning the Apple mobile device operating system (on top of the open-source Darwin kernel).

UI performance

  1. UILabel costs more than what you think
  2. Always start with serial queues, and only use concurrent queues as a last resort
  3. Avoid using dispatch_semaphore_t to wait for asynchronous work
  4. Don’t use UIView tags
