Sane library management for Xcode

leonard.ehrenfried@gmail.com

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?

Installation instructions

drag the OAuth2Client.xcodeproj into your project add OAuth2Client as a build dependency add OAuth2Client/** to your user header search path in the build settings link your target against OAuth2Client (drag the OAuth2Client product from OAuth2Client.xcodeproj to your targets Link Binary With Libraries) #import "NXOAuth2.h"

Why is manual installation problematic?

  • Error-prone
  • Upgrade path unclear
  • No transitive dependencies

Worst of all?

The library source is supposed to be added to version control!

Other languages and platforms have automated all of this

Python has easy_install/pip

Ruby has gem

JavaScript has npm

Java has Maven

Objective-C has ?

Enter Cocoapods

  • Library dependency management for Xcode projects
  • Community maintained
  • Written in Ruby
  • Modelled after Rubygems
  • gem install cocoapods

Great, how does it work?

Create an Xcode project Add a Podfile to your project folder Add your dependency to it pod install Compiles your library dependency as a static library Takes your project and puts it into an Xcode workspace Adds static library to workspace You open App.xcworkspace instead of App.xcproject Profit!!1!

Anatomy of a podspec

              
Pod::Spec.new do |s|
  s.name     = 'MBProgressHUD'
  s.version  = '0.5'
  s.platform = :ios
  s.license  = 'MIT'
  s.summary  = 'An iOS activity indicator view.'
  s.homepage = 'https://github.com/matej/MBProgressHUD'
  s.author   = { 'Matej Bukovinski' => 'matej@bukovinski.com',
                 'Jonathan George'  => 'jonathan@jdg.net' }

  s.source   = { :git => 'https://github.com/jdg/MBProgressHUD.git', :tag => '0.5' }

  s.source_files = '*.{h,m}'

  s.framework    = "CoreGraphics"
end
