Summary: Hi! I was editing a comment in some swift code, and as I typed, Xcode's responsiveness went away, almost like it was repeatedly processing the line with something exponential. Attached is the project in question, and a spindump and sample. I'll be attaching a dropbox link in a subsequent comment. Seems to be related to editing comments. Editing code around it is fine. Steps to Reproduce: Write Swift code Start an end of line comment with // Keep typing Expected Results: Editor stays super-responsive and I can type in the comment Observed Results: Editor gets.... Slow...er.... w.......i...........t.......h........ e.................. [SPOD] Version: Version 9.0 beta 4 (9M189t) 10.12.5 (16F73) Notes: I use all-black as my code colorization because of chromatic aberration in my eyeglasses. Configuration: Did not occur in Beta3. I don't recall seeing this in other projects. all UIKit (This particular project is a friend's Cocoa command-line application) Comments
