10. Translation Types • Professional Translation • Paying translation company to translate • Machine Translation • Google Translate, etc. • Crowd Translation • Using your social network to provide translations
11. Translate new strings • Make sure your translation service is integrated with your git repo.
13. Translate new strings • Make sure your translation service is integrated with your git repo.
14. Translate new strings • Make sure your translation service is integrated with your git repo. • Generate strings fi les from your code as part of Continuous Integration

24. Generating app descriptions based on language app_description_source.txt Nihongo is an offline Japanese dictionary, flashcard app, and reading assistant, designed to make the best use of the time you dedicate to studying Japanese. <en>* Over 180,000 words and 6000 kanji entries.</en> <de>* Over 115,000 native German definitions and 6000 kanji entries.</de> https://gist.github.com/chrisvasselli/ 51460cfee92ec3413de5ffe4b4b91460

26. Translate new strings • Make sure your translation service is integrated with your git repo. • Generate strings fi les from your code as part of Continuous Integration • Generate strings fi les from storyboards. • Generate app description from a shared app description fi le • Use Apple’s translations where possible
27. Using Apple’s Translations • Use Apple’s strings for common system vocabulary. • Supply these strings directly, don’t ask for professional translation.

40. The Problem • 10 screenshots • (minimum) 4 device types • 8 languages • 10 * 4 * 8 = 320 screenshots
41. Basic Setup Fastlane Snapshot + Frameit + Deliver • Create UI tests that navigate to the screens you want • Use Fastlane Snapshot to automate taking screenshots in all languages • Use Fastlane FrameIt to put screenshots in device frames and add titles • Use Fastlane Deliver to upload screenshots to App Store Connect https://docs.fastlane.tools/getting-started/ ios/screenshots/
