Understanding iOS Technology

Learn about the fundamental concepts of iOS technology including bundle IDs, simctl command, and how to open URLs on the iOS simulator.

What is bundle id?

  • The bundle ID is a unique identifier given to each app by its developer. In the case of Apple apps, their bundle IDs start with com.apple.

What is simctl?

  • The simctl command controls iOS simulator instances from command line. It’s very similar to the adb for Android.
  • It can be run via xcrun simctl. You can see help for simctl from command line by running xcrun simctl help
  • What you can do using simctl:
    • Listing all available simulators
    xcrun simctl list
    • Creating new simulator
    • Erasing simulator
    • Installing app inside simulator
    • Add photo/video to simulator and may more
