 ### Whitespaces around binary and unary operators.
-Rationale: Operators are usually special symbols(+-/)  and when they dont have enough whitespaces they make code much harder to read. The rule is rather universal and holds for all operators:

-One space before and one space after
-###Unary operators 
-Just once space either before or after the operator

+####Return early
+
+If you have to meet certain criteria to continue execution, return early.

+**Good:**
+```swift
+guard condition else { return error }

+**Bad:**
+```swift
+if (condition) {
