Swift Coding Style

I have specific coding style for Swift.

Follow Apple's Cocoa coding style. (Camel case, uppercases for abbreviations, etc.)
Openign braces { at same line.
```
    func exampleFunction1() -> Int {
    }
```
This is specifically because Swift does not support to put { at new line for closure syntax.
Fully descriptive name for any public interfacing elements.
You can use shortest name for local (that means will not be referred from another places) variable if their roles are (1)temporary, or (2)obvious and super-clean.
```
    func exampleFunction1() -> Int {
        let a   =   123
        let a1  =   a + 100
        return  a1
    }
```
It is too inefficient to figure out formal name for all local variables. Anyway sometimes you need to use formal descriptive names if roles of the variables are not super-obvious.

Use tabs to align assignment.

    func exampleFunction1() -> Int {
        let a   =   123
        let a1  =   a + 100
        return  a1
    }

Usually one tab is enough because most variable names are shorter then 4 letters.
