2. Adopt refurbished products, only by certified professionals. All things equal, except the price.  www.backmarket.com
3. fuck new.
4. Swift Scripting? !
5. Manage localization efficiently
6. Our technical context 1- SwiftGen 2- lokalise.co 3- Localization.framework
7. 1/3 - Use SwiftGen for safer translation code https://github.com/SwiftGen/SwiftGen
8. 2/3: Managing strings translations with lokalise.co + the SDK (OTA updates) https://lokalise.co
9. 2/3: Managing strings translations with lokalise.co + the SDK (OTA updates) https://lokalise.co
10. 2/3 - Link Lokalise with SwiftGen
11. 3/3: Create a dedicated Localization.framework for your app
12. + + = ❤
13. Two issues
14. Issue N°1: lokalise.co strings up to date • What about our string code integration with SwiftGen? • What about strings fall-back? • What about first launch? • If there is no network at launch? • What if lokalise.co is down?
15. Easy: download the last files versions from lokalise.co
16. Manually?
18. Let's make a Swift script!
19. 6 Steps 1. Make shell commands call possible 2. Create the API download calls with URLSession & Codable ⬇ 3. Multi-languages support ( 4. Create the zip unarchiving and copy files code 5. Use the command line parameters 6. Clean & make it beautiful

25. 4/6 - Create the zip unarchiving and copy files code
26. 5/6 - Use the command line parameters
27. 6/6 - Clean & make it beautiful
28. Issue 1: ✅ lokalise.co download now automated
29. Issue N°2: What about plurals? • There is no official SwiftGen template (yet) • Stringsdict rocks • Yes, we love SwiftGen • But, we love Swift more! ❤
30. What we want? in code
31. What we want? in L10n
32. Scripting time! (Quickly)
33. Format key-function
34. Format the L10n extension
35. Update your build phase • Make your script macOS compliant • Add the new plurals phase
36. Build your project!
38. Issue 2: ✅ Plurals with .stringdict files now correctly supported
39. Let's resume
40. Efficient Localization management ✓ Have single responsibility and substitution with a dedicated module ✓ Is Safe with L10n enum keys
41. Use Swift Scripts • Swift scripting is ✓ Easy and accessible for an iOS developer ✓ Powerful (shell calls, arguments, console printing, using Foundation (Codable, URLSession...) • Use your Swit scripts as: ✓ A custom command line tool ✓ As a custom build phase in your project
42. More ✓ Use Playgrounds to test & format it! ✓ Use aliases for your command lines, we are lazy
