2. W ? W ? A framework is a collection of... ...code ...assets ...images ...more
3. F != F != Dynamic vs static Bundle vs just code
4. P P Allows reutilization Favors encapsulation Favors defining boundaries
5. C C Harder to maintain Harder to prototype ↔ architect Slower iteration
6. H ? H ? Manual + git submodules... Carthage CocoaPods Swi Package Manager
7. M M Completely manual (download or copy) Git submodules ⚠ Detached heads ✅ Exact point in time In both cases, manual integration
8. C C Not centralized Manual steps More control
9. C P C P Well known Automated Less control ("blackbox")
10. S P S P M M New, less support Server projects
11. C P C P
12. P P .bash_profile / .zshrc / ... Installing export GEM_HOME=$HOME/.gem export PATH=$GEM_HOME/bin:$PATH $ gem install cocoapods --user-install
13. B B $ pod init $ pod install $ pod update $ pod outdated
14. P P platform :ios, '9.0' target 'MyApp' do use_frameworks! pod 'Alamofire', '~> 4.5.0' target 'MyAppTests' do inherit! :search_paths end end
15. S S PATCH: bugfixes, doesn't add features MINOR: new features, no breaking changes MAJOR: breaking changes MAJOR.MINOR.PATCH semver.org
16. S S Exact version  0.1 Comparators  > 0.1  >= 0.1  < 0.1  <= 0.1 Optimistic comparator  ~> 0.1.2  ~> 0.1
17. P . P . Allows pinning versions → reproducible builds Add it to the repo Alternatively, add Pods directory Using exact versions in the Podfile is not enough

19. P P $ pod spec create Lipsum Specification created at Lipsum.podspec $
20.

21. U P U P platform :ios, '9.0' target 'SampleLipsumApp' do use_frameworks! pod 'Lipsum', :path => '../Lipsum' #target 'SampleLipsumAppTests' do # inherit! :search_paths #end end
22. L ' ! L ' ! $ pod install Analyzing dependencies Fetching podspec for `Lipsum` from `../Lipsum` Downloading dependencies Installing Lipsum (0.0.1) Generating Pods project Integrating client project [!] Please close any current Xcode sessions and use `SampleLipsumApp.xcworkspace` for this project from now on. Sending stats Pod installation complete! There is 1 dependency from the Podfile and 1 total pod installed.
23. $ open SampleLipsumApp.xcworkspace
24. H H Remember public Development Pods pod update not needed
25. P P Create framework project Create podspec echo "4.0" > .swift-version pod lib lint Commit and push to repo Tag with version ("0.0.1") and push pod trunk push Lipsum.podspec --allow-warnings
26. N N Run tests Update podspec (version!) pod lib lint Commit and push to repo Tag with new version ("0.0.2") and push pod trunk push Lipsum.podspec --allow-warnings
27. P P P P Create a git repo Add: pod repo add private-repo https://github.com/xrubioj/swifty- framework-private-repo.git Push Podspec: pod repo push private-repo Lipsum.podspec Update your Podfile with source
28. U P U P platform :ios, '9.0' source 'https://github.com/CocoaPods/Specs.git' source 'https://github.com/xrubioj/swifty-framework-private-repo.git' target 'SampleLipsumApp' do use_frameworks! pod 'Lipsum', '~> 0.0.1' #target 'SampleLipsumAppTests' do # inherit! :search_paths #end end
