Pattern: Malformed whitespace around let/var

Issue: -

Description

let and var should be separated from other statements by a blank line.

Examples of correct code:

let a = 0
var x = 1

x = 2


a = 5

var x = 1


struct X {
	var a = 0
}


let a = 1 +
	2
let b = 5


var x: Int {
	return 0
}


var x: Int {
	let a = 0

	return a
}


#if os(macOS)
let a = 0
#endif


@available(swift 4)
let a = 0


class C {
	@objc
	var s: String = ""
}


class C {
	@objc
	func a() {}
}


class C {
	var x = 0
	lazy
	var y = 0
}


@available(OSX, introduced: 10.6)
@available(*, deprecated)
var x = 0

let x = bar as! Bar

Examples of incorrect code:

var x = 1
↓x = 2


a = 5
↓var x = 1


struct X {
	let a
	↓func x() {}
}


var x = 0
↓@objc func f() {}


var x = 0
↓@objc
	func f() {}


@objc func f() {
}
↓var x = 0
