| Interesting behavior (bug?) in Xcode / IB.... | |
| 1) Create new Single View project... | |
| 2) Add a couple objects to the default ViewController in Main.storyboard... | |
| 3) Add a new Storyboard via File -> New -> File -> Storyboard... | |
| 4) Back in Main.storyboard, select either View Controller or View Controller Scene... | |
| 5) Select Edit -> Copy (or just cmd+C) | |
| 6) In the new Storyboard, try to Paste -- can't do it... | |
| 7) Drag a ViewController to the new Storyboard... | |
| 8) Now try to Paste -- it works! |
