With the 10.2 update, I cannot get code completion working in one of my projects. I've reinstalled Xcode. I've nuked the repo and pulled it down again. I've deleted derived data. I've turned auto-complete on and off - and still nothing.
Other projects work, but there is no indication why this specific project keeps failing to provide auto complete
It says "indexing" for a hot minute and it doesn't seem to be indexing anything correctly.
I have the exact same problem. I had this issue with Xcode 10.1 with another project. The only thing that helped was starting a new project and add all files from the disk again. Painful if you have multiple targets like me 😟
It gets really annoying now.
Did you do a Clean Build Folder, forcing some reindex.
Yes I did, but it does not help. The usual tricks do not help:
- Clean build folder
- Delete derived data
- Close/reopen Xcode
- Restart mac
As I noticed Xcode is likely to mess up the pbxproj file, specifically some references in it.
OK, I've found a solution:
Xcode can mess with pbxproj file and can:
- break references
- leave obsolate references dangling
Close Xcode. Save your pbxproj file for sure.
I downloaded this tool: https://github.com/americanexpress/xcprojectlint
~/xcprojectlint --project XXXX.xcodeproj --report error --validations files-exist-on-diskYou should be watching for output like this:
/project.pbxproj:0: error: XXXXX/Vendor references files that are not on disk.Open the the pbxproj file and search for the folder indicated above (Vendor). Check all references under children of it and delete all obsolate ones.
Clean DerivedData. Open the workspace again. Try to compile. Fix any errors. Re-add missing files is needed.
The sad thing is that Xcode does not always fully follow up refactors, moving files/folders. The project still compiled though, but after fixing the pbxproj file many errors occured. This can be dangerous, so using xcprojectlint help a lot.
Did you try converting your project to Swift 5 ?
I do not get why it should help. Definitely the pbxproj file was "corrupted".
May be the lib called by API are different.
