Summary:
Designing, arranging and adjusting objects in the "Interface Builder" is currently only possible at 100% zoom. Esp. with iPad pro and tvOS this is a time wrecking and cumbersome process.

Other applications like Pages, Keynote, Numbers do support their editing and layout features at more than just the 100% zoom - and so should Xcode.

Steps to Reproduce (example):
1. open a storyboard for tvOS
2. add a navigation view controller and two ore more navigation controllers
3. zoom out to 50%
3. add segues to create a typical navigation stack between the view controllers

Expected Results:
At all zoom scales all editing features should work as they work at 100%.

Actual Results:
Xcode either zooms out to 100% zoom automatically and interrupts the segues creation or does not let the user create a segue. The solution involves heavy scrolling, missing targets and rearranging objects.

Regression: 
At the moment only the 27" iMac can display a full tvOS view controller with the usual palettes. For multi-monitor or MacBook usage this is a pain significantly wasting time and efficiency while developing for these platforms.

Notes:
It's important to note that more than just segue creation via drag&drop is affected by this limitation. Xcode should support editing in all supported zoom scales for (but not limited to):
- segues drag&drop
- view/scene drag&drop
- alignment of views
- resizing of objects
- creating objects by means of drag&drop from the objects palette
- selecting objects for inspection
- editing of layout constraints for Auto Layout
- display/editing of size classes
