A behind the curtain look at the iOS development workflow at ShopKeep.

Transcript

1. This is how we iOS at
2. · registers in brick & mortar stores, coffee shops · ~100M in funding, 250+ employees
3. Domain specifics
4. We don’t know what it is, we don’t know what it can be, we don’t know what it will be. We know that it’s cool. -- The Social Network
5. We don’t know what it is, we don’t know what it can be, we don’t know what it will be. We know that it’s cool. -- The Social Network
6. · we know what it is and people pay us money · a bug can cost people way more money App Store review process isn't exactly helpful · we don't have "a mobile app", it's a flagship we do talk to a backend, but it's a separate product
7. Teams
8. · roughly following Spotify's model squads, tribes, guilds, chapters · daily standup, planning and retro every 2 weeks
9. · management path x technical path director x principal engineer
10. Hiring
11. · prescreen is it reasonable to spend time on this candidate? ↓ · code sample anonymous, pull request review as all other code ↓ · 3 rounds of interviews anyone can veto
12. internal hiring · you already know they are a cultural fit · developers, QA, data science, product all have hires from sales/customer care · 2 iOS devs originally hired for Rails
13. Code
14. PR review · IMO #1 source of keeping our code quality up · o!en multiple reviewers no explicit assignment · immediate x non-blocking x chore
15. · CI on every PR, nothing gets merged without it 5000+ unit test cases, 1500+ UI test cases (KIF) · I'd like to move to monorepo every separate repo should be a conscious decision · almost moved Core Data → YapDatabase it'll be a beautiful day when we actually do still not an optimal solution though
16. Releases
17. · bus stop schedule 2015-07-17, 2015-08-28, 2015-10-09 release manager rotates between iOS engineers · current bus stop = beta, next bus stop = alpha nightly builds · frequent forward merges between bus stops
18. Builds
19. · same Jenkins for CI, betas, releases no one builds any production builds on their machine we used Travis for about a year, but it "couldn't handle our scale" · slaves spinning up VMs – Mac Pros + Parallels iOS DevOps definitely a thing, would hire someone for this · HockeyApp > TestFlight so far migrations!
20. Quality assurance
21. · manual testing dedicated team (we share them, but iOS has a lot of priority) a lot of features hard/expensive to automate · independent Appium (rspec) test suite · o!en multiple public betas before a release dedicated beta program manager
22. · to uncover deeper QA problems, you need senior iOS developers memory leaks, performance issues...
23. Analytics
24. · previously Mixpanel: gets expensive · Amazon Mobile Analytics → Looker open-source SDK, cheap, cross-reference with any other data
25. Personal growth
26. · weekly lunch & learn · monthly Code Smash = 5% time · chapters architecture, Ruby, security... · mentoring & 1-on-1s mentor may or may not be your manager · pairing encouraged · PR review "asynchronous pairing"
27. · fresh new office => hopefully host meetups · always be hiring
