In my experience it's pretty much impossible to get any kind of UI done in Xcode, at least as of Xcode 7. I'm a totally blind programmer who has a Macbook Air that I run windows on most of the time. I'm not sure if my issues with Xcode were do to a lack of experience with Voiceover on the Mac, lack of knowledge about iOS programming, or lack of accessibility in Xcode. It would be nice if Apple could come out with a basic guide targeted at Voiceover users to create a simple app that allowed you to enter text into a text box, click a couple of buttons and have something happen, etc. I've had a really ahrd time following any guides online to get started with iOS programming. Not sure what other blind developers experiences are though.
