I have done a first time install of both Xcode and Unreal Engine onto my MacBook Pro. Following a tutorial I notice that auto code complete does not work for most code options. I had tried re-creating the Xcode project and also starting Xcode by clicking on the project file. Neither of these worked for me.
I had a few posts suggesting that autocomplete won’t work with Xcode if Unreal Engine is installed into a location containing spaces. It appears that the latest unreal (4.15) is installed into the path:
/Users/Shared/Epic Games/
As a test I renamed the folder ‘Epic Games’ to ‘EpicGames’ (removed the space). I could no longer start UE from the launcher but I could start it manually (/Users/Shared/EpicGames/UE_4.15/Engine/Binaries/Mac/UE4Editor.app)
Auto complete now appears to work (after reindexing had completed, which took ages).
I don’t recall the option to choose the install location when I first installed it, and I don’t know how to uninstall unreal to check. I’m sure renaming is not the right answer but I think it shows the cause of the issue.
Is there a way to install into a working location without spaces in the path that will not break the launcher?
There is a link in the issue link that you posted above where one of the comments suggested that creating a symlink would allow the launcher to work, while still allowing Xcode to work without the spaces in the path. I’ve just tested it briefly with a new project and it does appear to work.
