CocoaPods - State of the Union

2 thirds of the CocoaPods core dev team discuss what you should really know about CocoaPods and where it's heading.

Slides obviously aren't as funny as me and @fabiopelosin but you can get the general gist and check out some of the new design work that's coming to CocoaPods soon.

14. All the things that you shouldn't know Sunday, 29 September 13 This presentation is focused on the internal information of CocoaPods necessary to easily overcome any issue of this young tool.
15. What Sunday, 29 September 13
16. CocoaPods takes a set of specifications to generate and setup a series of libraries which include the dependencies of the targets of a given project. Sunday, 29 September 13 Setting the context and explaining the basics with some emphasis on some less know point. - The Podfile is about targets. Don't get confused by the implicit target definition. -The Lockfiles, especially the Podfile.lock is as important as the Podfile and as accessible. -Specifications will be only declarative.
17. Podfile Lockfiles Podspecs Sunday, 29 September 13
18. Podfile Lockfiles Podspecs The Podfile specifies a list of targets which need to be integrated and their dependencies. Sunday, 29 September 13
19. Podfile Lockfiles Podspecs The Lockfiles store the information about the previous installation. There is one for the installation and one for your local sanbox. Sunday, 29 September 13
20. Podfile Lockfiles Podspecs Provide the declarative information necessary to build a single library. Sunday, 29 September 13
21. However the real questions are? How CocoaPods does this and why you should care? Sunday, 29 September 13

24. Analysis Downloads Pods project generation User projects integration Sunday, 29 September 13
25. Analysis Downloads Pods project generation User projects integration • Podfile is compared to the Podfile.lock • Version which should not change are detected • The user project is inspected • Dependencies are resolved • The information for each target of Sunday, 29 September 13
26. Analysis Downloads Pods project generation User projects integration • The resolved version of the Pods not available in the sandbox are downloaded • Unused files are removed Sunday, 29 September 13
27. Analysis Downloads Pods project generation User projects integration • The pods project is generated • The file references are added • One target per pod-target definition combination • One target to aggregate the pods of a target definition • Support files are generated • Xcconfigs are king!

28. Analysis Downloads Pods project generation User projects integration • The workspace is created • References to the aggregate libs and to the xcconfigs are created • The target is setup to use the aggregate lib as a dependency and the xcconfig file for configuration • copy resources script and the Lockfile check build phases are ad Sunday, 29 September 13

51. Sunday, 29 September 13 - Site - 07 Nov 2011 by Florien Hanke - v1.0 - 07 Nov 2011 by Florien Hanke - Came with a great search - Rudimentary Documentation for CP - v1.2 - Jan 2013 - docs.cocoapods.org - guides - v1.5 - July 2013 - CocoaDocs as a first class citizen - Private CocoaPods API - Search - Pod info - V2.0 August 2013 - Revised Branding - Revised Homepage - Revised Search - Revised Documentation - Separated Guides
52. Sunday, 29 September 13 Noticed that we weren’t seeing the kind of mobile stats I’d like
53. Sunday, 29 September 13 We’ve looked at the analytics, and our iOS usage isn’t where we’d like it to be. So there’s been lots of work on making the website mobile friendly
54. Sunday, 29 September 13
55. Sunday, 29 September 13 Focus on Search
56. Sunday, 29 September 13 Showing Stars, Forks, Project Maturity, % of documentented public methods/classes, README length Allowing inline previewing of the README similar to CocoaDocs Inline screenshots This should be enough to choose between all the UIAlertView+Blocks
57. Sunday, 29 September 13
58. Sunday, 29 September 13
59. Sunday, 29 September 13 Not just been looking at search, we’ve been thinking about ways to communicate with the users of cocoapods. Our README & Twitter are our current ways of getting new info out, but one is too technical and the other too temporary

75. Why? Sunday, 29 September 13 - [Joke] You might want to use this dependency automation thing unless you prefer your to use punch cards for that (apparently some still do). - Even if you're not a fan you might learn some tips and best practices for your workflows. - Abstractions are leaky - CocoaPods is still very immature - Life is good until CocoaPods breaks your project and suddenly all those little ponies reveal o be nothing else than overgrown rabid zombie rabbits - Adapt CocoaPods to your needs - Better tickets - Less blaming on maintainers ;-)
76. CocoaPods is an asset of the community and it can be only as good as we are. Sunday, 29 September 13
