Injection, or Controlling your Tools

The largest OSS projects in the iOS ecosystem comes from people who have said “the tools we have are insufficient” and were unwilling to wait for Apple to fix them. There are still a lot of holes to be filled and as individuals we should be devoting time to helping ourselves and each other.

This talk is about the my struggles with accepting that sometimes it’s up to you to be the change you want in the world.

31. - Xcode Plugin
    - Keeps track of all changed files
    - Compiles the changed files via terminal to bundle
    - Bundle is passed to an Injection server in your app
    - Server receives bundle, and loads it
    - Server replaces methods in old classes with new ones
    - Server sweeps though all app memory for instances
    - Server notifies all objects they’ve been changed
