Transcript

1. PUTTING TOGETHER THE BEST CI WORKFLOW FOR SWIFT APPS Dennis Pilarinos, Founder -
2. Common software development practices Developers and users working together to build great applications Create Fix Share Feedback Development Team Users Test
3. Systems and workflow The systems required to build great software Continuous Integration Analytics & Crash Reporting Feedback Continuous Deployment Complex & Cumbersome Difficult to Provision Users Inefficient & Ambiguous Incomplete & Lacking Context Developers Mobile
6. CONTEXT MATTERS
7. ZERO CONFIGURATION CI
8. 19 pages just to get your app built and deployed “I spent about 10 hours googling cryptic error messages, when trying to configure the build.” “...if you haven't got a few years of linux admin under your belt, you can write off the rest of the week.” “...in other words: it sucks at building and testing software.”
10. FRICTIONLESS DEPLOYMENT
11. OR
13. FEEDBACK FROM TESTERS
16. CONTEXTUAL CRASH REPORTS
19. KEEPING UP WITH XCODE
22. LET'S LOOK AT THE DATA
23. Examples Data from a variety of world class teams
24. WHERE’S THE CODE?
25. Cloud Hosted vs Self Hosted Cloud 95% Self Hosted 5%

31. watchOS adoption WatchOS 3% Total iOS 97% • Vast majority of apps don’t include Apple watch apps
32. Are people developing tvOS apps? • Relative to iOS apps in development, tvOS is vanishingly small tvOS Apps 0.3% iOS Apps 99.7%
33. CARTHAGE? COCOAPODS?
34. Cocoapods & Carthage Both 2% Neither 23% Carthage 8% Pods 66%
35. What version of cocoapods do teams use? 0.39 1.0 betas 1.0 1.0.1 1.1.0 betas 1.1.1 1.2.0 betas 1.2.0
36. Do teams check in the Pods folder? • Gives more control, but can cause more difficult merge conflicts Pods folder 54% No Pods folder 46%
37. What about larger teams? • For teams of 5 or more, do they check in the Pods folder? Pods folder 39% No Pods folder 61%
38. 2699 Unique Pods are referenced
39. Pods used in more than 15% of apps Dominated by Google, Facebook, Realm along with a number of interesting community projects Fabric 49% Crashlytics 47% Alamofire 41% AFNetworking 40% Bolts 38% SDWebImage 37% FBSDKCoreKit 36% FBSDKLoginKit 31% GoogleAnalytics 29% MBProgressHUD 28% GoogleUtilities 28% GoogleSymbolUtilities 27% GoogleInterchangeUtilities 25% FirebaseAnalytics 21% FirebaseInstanceID 21% SwiftyJSON 20% Realm 18% FBSDKShareKit 17% RealmSwift 16% SVProgressHUD 17% Google 17% CocoaLumberjack 16%
40. Test Related Pods Very few projects contain test related pods OCMock 10% Nimble 7% OHHTTPStubs 5% KIF 5% Nocilla 4% Expecta 2% FBSnapshotTestCase 2%
41. WHO WRITES TESTS?
42. Tests • Which Xcode projects contain tests? No tests 39% Has tests 61%
43. NATIVE VERSUS “HYBRID”
44. Native vs Hybrid Hybrid 10% Objective-C / Swift 90%
45. React Native, Ionic, and other hybrid apps • Significant number of apps built with React Native Other Cordova 6% Ionic 26% React Native 68%
46. 1/3 of React Native apps also use cocoapods
47. HOW UNIQUE IS MY WORKFLOW?
48. Custom Scripts Added custom scripts 14% No scripts 86%
