5. cocoapods.org “CocoaPods is the dependency manager for Objective-C projects.”
6. Dependency Manager
7. dependency?
8. System Frameworks
9. Reusable Components
10. Third Party Code

12. “Drag the *.h and *.m file to Xcode”
14. Static Library
15. Frameworks
17. “dependency hell”
18. A -> C (version 1) B -> C (version 2)
19. A -> C (version 1) B -> C (version 2) C -> D (version 3) E -> D (version 4) F -> B (version 5)
20. Better way to manage dependency?
21. rubygems pip npm
22. CocoaPods Basic
23. Installation
24. sudo gem install cocoapods
25. pod setup
26. Project Setup
27. cd MyApp! pod init
28. Podfile
30. “The Podfile is a specification that describes the dependencies of the targets of one or more Xcode projects.” cocoapods.org
31. DSL for dependencies
37. Podspecs
38. “A Podspec, or Spec, describes a version of a Pod library.” cocoapods.org
43. Repo
44. “The Specs Repo is git repository that contains the list of available pods.” cocoapods.org
46. “Every library has an individual folder, which contains sub folders of the available versions of that pod. ”
48. Install Dependencies
49. pod install
51. What happened when you run pod install ?
52. Update Podspecs Repo
53. Resolve Dependency
55. Semantic Versioning http://semver.org/
56. 1.6.4 MAJOR.MINOR.PATCH
57. MAJOR - incompatible API changes
58. MINOR - add functionality in a backwards-compatible manner
59. PATCH - backwards- compatible bug fixes.
60. 1.6.4 MAJOR.MINOR.PATCH
61. Download Dependencies
62. git hg svn bzr http
63. Generate Pods project
64. Generate workspace
66. Advance Topics
67. Making a CocoaPod
68. pod spec create MyLibrary
69. MyLibrary.podspec
71. pod lib create MyLibrary
72. !"" Assets! !"" Classes! #"" ios! #"" osx! !"" Resources! !"" Example! #"" Podfile! !"" CHANGELOG.md! !"" LICENSE! !"" README.md! #"" MyLibrary.podspec!

75. Example/Podfile
77. Release Pod
79. Publish your pod to public Repo
80. Fork the CocoaPods/ Specs repo
81. .! !"" Specs! #"" [SPEC_NAME]! #"" [VERSION]! #"" [SPEC_NAME].podspec
82. .! !"" MyLibrary! #"" 0.1.0! #"" MyLibrary.podspec! #"" 0.2.0! #"" MyLibrary.podspec
83. Send a Pull Request
84. Your Private Pods
85. Specify your own Podspec
88. Create Your Repo
89. .! !"" Specs! #"" [SPEC_NAME]! #"" [VERSION]! #"" [SPEC_NAME].podspec
90. pod repo add REPO_NAME SOURCE_URL!
