Summary:
Our project.pbxproj is 4.1mbs. With Xcode 9.3 when I clicked "Update to recommended settings" Xcode hung for ~5 minutes before I force quit it. Afterwards I let it run again for longer and it did update correctly (I'm not sure how long it took)

Steps to Reproduce:
1. Open a large Xcode project in Xcode 9.3 for the first time
2. Click Update to recommended settings in the issue navigator

Expected Results:
The next window with the settings that are changing appears

Actual Results:
Xcode beach balls for a few minutes

Version:
Xcode 9.3 (9E145)

Notes:
Attached is the CPU usage and hang report
