Pattern: Malformed closure spacing

Issue: -

Description

Closure expressions should have a single space inside each brace.

Examples of correct code:

[].map ({ $0.description })


[].filter { $0.contains(location) }


extension UITableViewCell: ReusableView { }


extension UITableViewCell: ReusableView {}

Examples of incorrect code:

[].filter(↓{$0.contains(location)})


[].map(↓{$0})


(↓{each in return result.contains(where: ↓{e in return e}) }).count


filter ↓{ sorted ↓{ $0 < $1}}
