None
These days... • real time quotes w/ streaming • manage
watchlist • personalized news • portfolio tracking
Re-written from an older version starting Jan 2013 • ~12000
commits • ~6000 PRs • ~50 people have committed • ~70 Pods
Today • 5 iOS devs • 1 Engineer/Project/Product Mgr •
~1.5 (shared) designers • 14 releases this year • iOS 8+ (next release)
Basic flow • master is always shippable to Apple •
develop is (almost) always shippable to Dogfood • feature branch off of develop
Code review • team does via PR • larger items
done in person with team or architect • mentoring via PR (blocker vs feedback)
Private pod-spec • ~100 internal pods • ~50 more people
have shared code in our app • Ads, Analytics, Accounts, Messaging, Side Menu, ... • SemVer is important in managing this • Cutting a major version requires larger review
Testing • Unit tests (Specta/Expecta) • Snapshots • UIAutomation Monkey
testing • QA Team does manual regression testing
Chat is harder than expected • Yahoo Messenger • Slack
• HipChat • IRC • iMessage • Skype
CI is harder than expected • Jenkins with other stuff
• Swift was fun • Laptops are mostly faster than Mac Mini’s • Each build generates ~70MB of logs
Tools • Enterprise Github • JIRA • Sentry • Splunk
• Sketch • InDesign • GoogleDrive • Paw • Charles Proxy • Seamless
Open Source • YMCache • YMPromptKit • cocoapods-blacklist
Great Resources • Usability Studies • Senior Architects • Dogfood
users
2 types of weekly office hours • Cross team in
NYC • With Senior Architect in SNV • Special for goals (e.g. performance)
Weekly “What do you want to talk about?” Meeting •
write descriptions on post-it notes • clarify for others if needed • each person has 2 votes • highest votes are discussed for 15-30 minutes each
Internal, organized learning • Android • OpenGL • React •
Tech Associates • Stocks, Technical Analysis, Options, etc
