function-whitespace

Every function and method declaration should have one blank line before and after itself. An exception to this rule are functions that are declared at the start of a file (only need one blank line after their declaration) or at the end of a file (only need one blank line before their declaration). Comments immediately before a function declaration (no blank lines between them and the function) are considered to be part of the declaration.

Preferred

func function1() {
  var text = 1
  var text = 2
}

function1()

// a comment
func function2() {
  // something goes here
}

struct SomeStruct {

  func function3() {
    // something goes here
  }

  func function4() {
    // something else goes here
  };

terminating-newline

Verify that source files terminate with exactly one \n character. This ensures that the last line of the file is valid according to the POSIX standard. Also see No Newline at End of File for more information.

Swift source files should terminate with exactly 1 \n character, not 0 nor more than 1.

let myConstant = 42<eof></eof>
