Preface: Learn a lot of days and hours of swift, feeling or quite a lot of ~ ~

1, OC is a C language-based language, before learning the basis of C language, so for the ' * ' These pointers are relatively easy to understand. Asked other programmers, the ' * ' pointer in OC is not very understanding, OK. I'm still glad I understand that.

2, Swift ~ about OC Uikit Frame basically unchanged, is the method name simplified a bit. Simple, but it feels pretty good. It may be that Apple is pushing swift, and I'm getting the idea that I don't want to use OC. But before OC write a lot of extension, class method, now use can directly with bridge file, but always feel strange. In the future, it's okay to use Swift to re-knock those OC files again.

Body:

1, fast experience. Playground

Create a new playground with some views on it, and you can go directly to the right. It feels easy to do some simple tests, no com+r.

2. Swift constant, variable, condition judgment

3. Swift string

4. Swift Array

5. Swift Dictionary

6. Swift function

7, Swift closure is the block in OC

8. Swift Circular Reference
