   management sucks 3. CocoaPods is the new hotness 4. Getting started is easy 3

4. Premise: using open source is good (more like “promise” amirite)

5. Why?

6. Why? • Build applications faster • Write less code •

   Build better applications • Expose yourself to other devs’ code 6

7. “Library”?

11. File Management

12. None

13. This is a bad idea.

14. A Bad Idea • Dependency management Hell • Lack of

    separation of code • No versioning of libraries • Per-file compiler flags 14

15. Git Submodules

16. Git Submodules • A submodule is like a pointer to

    another repo • Another repo at a specific point in its history • Checks out code into your directory • Submodule interface is not mature • Still have to specify per-file flags • Requires command-line interface 16

19. Git Subtree I don’t even.

21. CocoaPods

22. CocoaPods • Manages versions and dependencies • Solves a lot

    of problems with file-management • Easy to use 22

23. CocoaPods is to Objective-C as RubyGems is to Ruby

24. What is a CocoaPod

25. CocoaPods • A CocoaPod is a file that specifies a

    library • Name, dependencies, version, etc • CocoaPods is a tool to manage these specs 25

26. How does this work?

40. Best Practices • Don’t check in your Pods directory •

    Use .gitignore • Specify explicit version numbers • Inhibit pod warnings 40

41. Demo

42. Creating a Library

43. Creating a Library • Specify a license • Write a

    good README • Include screenshots • Include sample library usage • Keep files organized 43
