  <p>Button B looks bad when is connected:</p>
  
  <pre><code>import Cocoa
  
  class ButtonsC: NSViewController {
  
      @IBOutlet var b: NSButton!
  
      override func viewDidLoad() {
          super.viewDidLoad()
      }
  
  }
  </code></pre>

  <p>and if I connect the button A, button B looks nice and A looks bad</p>
  
  <pre><code>import Cocoa
  
  class ButtonsC: NSViewController {
  
      @IBOutlet var a: NSButton!
      @IBOutlet var b: NSButton!
  
      override func viewDidLoad() {
          super.viewDidLoad()
      }
  
  }
  </code></pre>

  <p>How can I fix it? or what kind of code in my project may be causing that?</p>
