In my View Controller screen in Xcode I've added some horizontal and vertical lines from the usual Library of buttons, windows, etc. In my app I have a clear window with just the title bar and an input/output text area shown. I want to have a visible border around the window. The added lines work but they're very light. I don't see how to edit that in Xcode or how to have my app modify them - or another way to get a visible border around my clear window. The rest of my simple app is working great. This is the last detail and I'm really stuck.
