Open Radar

 
Summary:
Xcode aggressively adds asset catalog Contents.json to the Git index, even when add and remove files automatically is unchecked in Xcode’s source control preferences.

Steps to Reproduce:
In Xcode preferences > Source Control turn on Enable Source Control but turn off Add and remove files automatically.

1. Create a new iOS project in Xcode 8 with the single view template and commit the result into a Git repository, or see the attached folder which does exactly this.
2. Open the Xcode project in Xcode 9
3. Navigate to the asset catalogue
4. (Optional) navigate away from the asset catalogue (this just demonstrates that the monitoring is continuous)
5. Run `git status`
6. Run `git reset —hard`
7. After a short delay (less than 1s so pretty much straight away) run `git status`

Those last two steps can be repeated many times.

Expected Results:
• Git index should not be modified by Xcode since I set it not to.
• Xcode should not repeatedly modify the file.
• It would be nice if Xcode didn’t ever modify the file on its own, but I wouldn’t be too bothered if it did this a single time in response to user action, and I can see there is some need to do this.

Actual Results:
At 5 there is a modification of Contents.json in the asset catalogue adding some new entries and this is added to the Git index. At 7, the same is the case.

• Modifying the file once on opening the asset catalogue would be not ideal, but whatever.
• Repeatedly modifying the file (even when viewing some other file in Xcode) is bad. It puts me in a bad mood by telling me I’m not in control.
• Modifying the Git index when Xcode is set not to do this is bad. I make carefully make logically separated commits, then Xcode comes and tries to shove stuff in wherever.

Version:
9.0 beta 4 (9M189t)

Notes:
At one point this stopped happening until I navigated to the asset catalogue again.
