The following source code will create a blue NSButton using an inline image which is a blue colored rounded rect near the same size as the button. The button title color was changed to white to make it more visible.

// **** Inline Image **** //
let fillColor = NSColor(calibratedRed: 0.0, green: 0.0, blue: 1.0, alpha: 1.0)
let image = NSImage.init(size: NSMakeSize(128.0, 22.0))
let imgRect = NSMakeRect(0.0, 0.0, 128.0, 22.0)
image.lockFocus()
let roundedRect = NSBezierPath (roundedRect:imgRect, xRadius:4, yRadius:4)
fillColor.set()
roundedRect.fill()
image.unlockFocus()

// **** Button **** //
let myBtn = NSButton (frame:NSMakeRect( 150, 100, 140, 24 ))
myBtn.bezelStyle = .rounded
myBtn.image = image
let attributes: [NSAttributedString.Key: Any] = [.font: NSFont.systemFont(ofSize: 12), .foregroundColor: NSColor.white]
myBtn.attributedTitle = NSMutableAttributedString(string: "Show Window", attributes:attributes)
window.contentView!.addSubview (myBtn)
