[swift-evolution] [Discussion] Design guideline rule for `:`

[Adrian Zubarev]

Should there be a design guideline rule for colons : in Swift?

I see people doing things like this:

protocol A : B {}

// VS.

protocol A: B {}
func foo<T : A>() -> T { … }

// VS.

func foo<T: A>() -> T { … }
var value : Type

// VS.

var value: Type
[key1 : value1, key2 : value2]

// VS.

[key1: value1, key2: value2]
I prefer the second style, where there is no whitespace between lhs and the : symbol and there is also a whitespace after :. Example: something: somethingElse
