The `NoEmptyLinesOpeningClosingBraces` swift-format option will remove blank lines from the beginning/end of blocks, eg. ``` func myFunc() { var x = 3 return x } ``` is reformatted into: ``` func myFunc() { var x = 3 return x } ``` But comments are ignored, eg. ``` func myFunc() { // Some comment here // Do a thing var x = doAThing() // Some other comment here } ``` ends up as: ``` func myFunc() { // Some comment here // Do a thing var x = doAThing() // Some other comment here } ``` I would expect the input to remain unchanged in this particular case. rdar://141589363
