A talk I gave at CocoaHeads Berlin

1. COCOAPODS
Sane library management for Xcode

2. SO, YOU'RE STARTING A NEW XCODE PROJECT
Look for some libraries to use in your project
Maybe an OAuth ibrary?
How to import it into your project?

3. INSTALLATION INSTRUCTIONS
1. drag the O u h C i n . c d p o into your project
At2letxoerj
2. add O u h C i n as a build dependency
At2let
3. add O u h C i n / * your user header search path in the build settings
A t 2 l e t * to
4. link your target against O u h C i n (drag the OAuth2Client product from
At2let
OAuth2Client.xcodeproj to your targets Link Binary With Libraries)
5. # m o t " X A t 2 h
ipr NOuh."

4. WHY IS MANUAL INSTALLATION PROBLEMATIC?
Error-prone
Upgrade path unclear
No transitive dependencies

5. WORST OF ALL?
THE LIBRARY SOURCE IS SUPPOSED TO BE ADDED TO VERSION CONTROL!

6. OTHER LANGUAGES AND PLATFORMS HAVE AUTOMATED ALL OF
THIS
Python has e s _ n t l / i
ayisalpp
Ruby has g m
e
JavaScript has n m
p
Java has Maven
Objective-C has ?

7. ENTER COCOAPODS
Library dependency management for Xcode projects
Community maintained
Written in Ruby
Modelled after Rubygems
gmisalccaos
e ntl oopd

8. GREAT, HOW DOES IT WORK?
1. Create an Xcode project
2. Add a P d i e your project folder
o f l to
3. Add your dependency to it
4. pdisal
o ntl
5. Compiles your library dependency as a static library
6. Takes your project and puts it into an Xcode workspace
7. Adds static library to workspace
8. You open A p x w r s a e
p . c o k p c instead of A p x p o e t
p.crjc
9. Profit!!1!

12. IN-HOUSE DEVELOPMENT
Referencing a local folder in a p d p c
ose
Host your own repository of p d p c
oses

13. RANDOM FEATURE OVERVIEW
Last night: 589 pods
Contributing is easy, just fork and create a pull request
Handles difference between ARC and non-ARC dependencies
: e t : e scopes available
ts/dv
iOS and OSX dependencies
