title: How to open .nib file?
body: <p>I cannot open them, XCODE just opens the application photo in XCODE and that's it. No, I cannot create a duplicate and show package contents. Any other guesses? Specifically, I'm looking to change Apple's Touch Bar functionality on PRE-EXISTING APPS. After tons of digging around to find where the TouchBar 'application' is, I've come to the conclusion that it is located in the .NIB files (new interface builder).</p>
