Completions in XCode


I’m trying to set up my development environment to submit a PR for the CrashReporter source. I’m able to build, run and debug the Engine source, however while browsing the code in XCode 12 I can’t seem to get Jump to Definition to work and the syntax highlighting and completions are sparse at best. I’ve followed the steps for Mac listed here. Are there any additional steps I need to take to get Completions or Jump to Definition to work in XCode?
