1. Porting Obj-C to Swift Justin Sheckler, Etsy
2. Should I port my code?
3. Maybe!
4. You’re still using Obj-C (for now, at least)
5. Read the Docs! http://bit.ly/objc2swift
6. Adding Swift to an Existing Project
7. Just add a new file and go
8. Your New Best Friend: The Bridging Header It imports Swift classes into Obj-C.
9. Point to custom Bridging Header in Build Settings
10. Where do I Start?
11. But, Can I Import Swift Back Into Obj-C? Yes! But it works totally differently. ಠ_ಠ
12. The Compatibility Header Your new second-best friend.
13. Let’s Demo! http://bit.ly/objc2swiftdemo
14. Gotchas! • Be careful of custom Obj-C types in Swift arguments • May need to cast primitive types to/from plain-C APIs • Obj-C/Swift bridges may still be buggy
15. Questions? @jayKayEss http://bit.ly/objc2swift (Apple docs) http://bit.ly/objc2swiftdemo (My Demo)
