Status:Open Resolved:
Product:Developer Tools Product Version:Xcode 10.1
Classification:Crash/Hang/Data Loss Reproducible:Always
 
Summary:
This is reproducible. Every time I try to open an assistant editor in the specified reproduction steps, it crashes.

Even option clicking on a file failed.

Steps to Reproduce:
1. Open a file
2. Open a vertical assistant editor with another file
3. Open another assistant editor to horizontally split the vertical assistant editor.
4. Hit command-enter to close the assistant editors
5. Try to open a file in a split


Expected Results:
Either: 
a) It asks what split I want it in of the 3 (even though the assistants are no longer visible on screen)
b) It opens in a vertical split (no more horizontal split I had in the assistant before)


Actual Results:
It crashes

Version:
Xcode 10.1

Notes:
Recovery:
I had to click the assistant editor button to show the assistant editors I had opened.
