title: ViewController Layout Help Needed
body: <p>I'm using XCode to build a UI for a countdown timer/metronome app.  After struggling with layout constraints, I discovered vertical and horizontal stack views, which I thought would make things much easier.</p>
  <p>However, the outermost stackview's boundaries appear to be outside the view of the device.  I removed all the layout constraints, but that didn't make any difference.</p>
  <p>Here's a partial screenshot of the project in XCode:</p>

  <p>Sorry if this question has been asked before - I looked but haven't found anything.</p>
  <p>I'm a professional software developer for the last 30 years or so.  The languages I work with on a daily basis for the last 20 years or so are Java, C++, and Fortran.  So dealing with UI layout in IOS is frustrating, to say the least!</p>
  <p>Thanks in advance for any help!</p>
  <p>Edit: Here's a screenshot of the uppermost stack view's size inspector: <a href="https://i.stack.imgur.com/sufEt.png" rel="nofollow noreferrer">size inspector</a></p>
