Summary:
In Xcode 7, when editing a playground, the input point keeps jumping to the beginning of the file.  In addition, while editing text disappears and sometimes partially reappears.  As requested in the forums, I have included a screen recording of the activity.

Steps to Reproduce:
1) Open Xcode 7 Beta 1 or 2
2) Create a new playground or open an existing one
3) start typing new code

Expected Results:
Flawless text entry

Actual Results:
Unusable text entry due to entry point constantly shifting to start of file.

Version:
Xcode 7 Beta 1 and 2, OSX 10.10.4

Notes:
This should corroborate another report: bug 21677709
I know of at least one other developer in my group who is having this issue.

Configuration:
Occurs always 
My current configuration
MacBook Pro Retina 15" 2.7GHz i7 16GB 512SSD
