I've got serious issues with XCode right now and i cant really figure out what to do, or even whats wrong.
The project i'm working on was working perfectly yesterday, but today when i started it i got like 20 "Redefinition of enumerator" errors, and to the point where "Too many errors emitted. Stopping now".
The wierd part is that ALL my backups of the project does this aswell. Even the ones from 2,3 or 4 days ago which hasnt been altered.
No other project seems to be affected by this.
I've tried Cleaning the build, removing Derived data, checking for duplicate files somehow (even though that shouldnt be possible), all linker seems to be in order. Anyone got any tips for me?
Thank you!
you should import
#import "Facebook.h"
instead
#import <FacebookSDK/FacebookSDK.h>
I just had this exact problem about "Redefinition of enumerator" errors coming out of nowhere.
The problem was that accidentally (maybe some unintended drag with the mouse) I had copied one of the project directories into some other, thus duplicating it.
On the other hand I use git and generally was using 'git status -uno' which hides untracked files.
So I was not seeing the untracked duplicated directory that was duplicating enums in the project, from my perspective I had a clean HEAD with weird errors :S
Lesson learned: use .gitignore rather than '-uno' option
This issue still happens in 2019 smh.
If you get this go check File->Workspace Settings and set build system to Legacy Build System. This should fix the issue.
I had the same error and was really stuck. But found that the project folder nam had white spaces. I changed that and the error went off!
Eg: Changed folder name My Project to MyProject
For anyone has the same problem, who pulled out hair for hours/days.
Let's double check and remove redundant Header Search Paths, delete Derived Data if needed.
After that, the issue will be resolved.

This may sound strange, but I am having issues with Xcode mixing branches, or at least messing everything up.
I created a new branch (v1.4), then created a new data model and renamed an entity. Had to switch back to previous branch (v1.3) to check something and I get errors at run time on v1.3, it's looking for the new entity name from Branch v1.4 - what the %$^#% is happening. I searched the files, the new entity name is nowhere in v1.3.
I switch branches again to v1.2 and it ran fine. So, switched to V1.3 again - nogo. Switched back to v1.2 and it has the same issue now, runtime error because it can't find the new entity name.
What is happening? Anyone else have this issue?
Any thoughts/suggestions would be greatly appreciated.
OS X 10.11.6
Xcode 7.1.1
==[EDIT]===
I am not real familiar with GIT, just starting to learn. I ran the couple commands as mentioned, get nothing for either git diff commands.
Running git status --ignored I do get multiple files as untracked - still working on understanding why (Separate issue) - couple object files and 2 data models (Was 3, but manually added one to commit.
Also I get 3 ignored files:
.DS_Store
projectName.xcodeproj/project.xcworkspace/xcuserdata/
projectName/.DS_Store
That's as far as I've gotten. Not familiar enough with git to know if these ignored files are the ones I should delete.
Second option - will restoring from time machine fix this? It may be a little extra work for me to recreate v1.4 but probably less time than I've already spent trying to figure out how to fix it.
I do appreciate both comments so far - thank you.
==[SECOND EDIT]==
Thanks again for your comments.
However, do to time and schedule I perform a Time Machine backup before ElpieKay posted the last comment, so I will not be able to test it.
Reverting back did "fix" it as you'd expect, but I did lose several hours of work but life happens. I will keep this for if/when this happens again and try the git clean -df to see it fixes it.
On a side note - while I was switching back and forth between V1.3 and V1.4 trying to figure this out, 2 of the model versions disappeared on v1.4 - i.e. the name turned red in Xcode and when I viewed the contents of the file they were missing. I do not know if this is related or not, but I thought I would mention it. This happened one other time and I thought maybe I did something - I did a time machine restore to fix it last time. Wonder if git clean -df would have fixed it.
I just finished skating around that infamous "cannot load main class start" thing, and I got blindsided with a sea of errors:
A friend suggests it might have something to do with com.google, but ultimately can't help me.
I haven't made a single alteration to any of the code so far. Eclipse just started up not being able to run and stayed that way. I think there's a way to fix it but it would require making acute changes at the sight of every single error; work that could be wiped by a cleanup if I'm proved wrong.
Anyone have a clue what the issue is? Thank you for the trouble.
UPDATE: Adding guava as a library relieved the error involving com.google, but threw in a handful of others. This one class file contains 3 of the most common unresolved types I've seen scattered throughout: Logger/LogManagaer, PropertyMap, and CrashReport
Your general problems revolve around not having dependencies in the build path. Eclipse's error messages are pretty clear about this; e.g. if a package name is underlined in red and can't be found, then that means it can't be found, and the obvious solution is to add the library that provides it, so that it can be found.
In virtually all cases here, a Google search for the missing packages and classes will lead you to the packages that contain it.
For each unresolved dependency, find the library, add it to the build path, then move on.
I also suggest consulting the documentation that comes with the source code you are attempting to compile, which often simply lists the dependencies, thus saving you the trouble of hunting them down as you go.
While we could do the internet searches for you and hash this out one step at a time, it's both better and faster for you to do it yourself. Better because if you're messing around with Minecraft source, having at least a basic knowledge of how your tools work is going to help you (I also suggest some of the material at http://docs.oracle.com/javase/tutorial/). Faster because the turnaround time of typing package names into the Google search box is a heck of a lot faster than constantly updating your question here and waiting for replies.
It looks like you are missing the Google Collections package, which now is called Guava.
Download the jar file, and add it as a library.
Since I started using CocoaPods, I've been having weird location related messages all the time, and some arch-related ones too.
I've been trying the whole day to figure out why it was happening, until I create a new Xcode project from scratch and realize the issue wasn't project-related all along.
Here's what's happening:
I always get those everywhere as well:
Not sure if related but I get those often too:
Anybody has those as well? What should I do?
Thanks!
I had to switch Build Active Architectures Only for debug to Yes and it let the build run.
I started adding comments to the code while i am developing the app (objective-c). The bad thing which i am noticing is the breakpoints and warning or error reporting, it is actually showing a wrong line number or pointing to incorrect line number, is there a solution for this problem. Thanks.
This is usually a problem with your Derived Data, the build products that are cached after each build so they don't have to be rebuilt if they aren't changed. The problem is, sometimes Xcode doesn't recognize a change, and what you see in the editor no longer matches the build product. Clean your product with Shift Command K to do a full rebuild. This should fix the inconsistencies you're seeing.
On both Xcode 4.4 and 4.4.1 I'm experiencing the same issue in that with the specific project I'm working on, I don't seem to be able to rename any classes or variables from the Refactor menu option.
Each time I try and do a rename, I type in the new name for the class/variable and click Preview at which point the bottom left begins a spinner with Finding files.... However, I then get a message saying:
The selection is not a type that can be renamed.
Make a different selection and try again.
I'm pretty sure that this is not an issue with my specific install of Xcode, because I can refactor other projects fine, it's just that I can't seem to be able to refactor this specific project.
Anyone with any ideas? I don't have any particularly exotic configuration for this project, it just seems to be a random affliction. I've deleted all of my derived data and re-indexed, but that doesn't seem to help.
Since it works OK in other projects, I'm thinking one thing I could try to do is re-generate the actual project file(s) itself. I don't know if there is a way to do this automatically?
If they're in dropbox get them out of there. It mangles project files. I've had it happen numerous times and at times it makes refactoring > renaming not work.
I have managed to solve this issue after trying many different things (tweaking project settings, pch, etc.) and it turns out there was a very simple (and totally counter-intuitive) method of fixing this issue.
All I have done is:-
Copy my entire project folder (so from Project to Project Copy).
Move Project (the original folder) to trash.
Rename Project Copy to Project.
Mysteriously, everything now works fine.
I really cannot figure out why this works. As mentioned previously, I had already deleted all derived data, etc. so I don't know why this should make things spontaneously work, but it does.
Would appreciate anyone who is able to shed some light on this as it does expose just how fiddly Xcode can be, and any understanding of what goes on under the hood is always beneficial.
Sounds like a buggered index.
I usually use the nuke from space option to delete everything in the derived data directory.
Unless you have changed it (I change mine to /tmp/bbum-derived), it'll be at:
~/Library/Developer/Xcode/DerivedData
Thus, I'll quit Xcode and do:
rm -rf ~/Library/Developer/Xcode/DerivedData
Yes, it is a bit brute force, but it works. You can likely force Xcode to rebuild the index from the UI, but I never bother. Of course, I'm also installing quite a few "odd" builds of this and that as a part of my day job...
(that is an rm -rf. It means "nuke everything and don't ask" in unix parlance. It is dangerous. Do not mistype that command.)
It seems you have an active selection somewhere in the gui, perhaps some of your files or classes are selected ? Try unselect in every sub window and retry refactoring.
I'm a bit late to this thread, but I ran into the same problem today and I was able to get it to finally refactor correctly, thought I share it.
So in large part I did what bbum said, I closed xCode, nuked the Derived data for the project the class files were in and re opened the project. Doing just that, it didn't work; the key, I found (at least for me), is that I had to do a clean (command shift k) after xCode restarts. After that I was able to rename the class files again :)
Also as a side note, my project is divided into the main project, and a static library. When I had to rename classes in the static library, I had to quit the main project and do what I described in the static library itself. Somehow I got the same error described in the question when I tried to do the refactor/rename from the main project.
Good luck!
This thread was very helpful for me in determining the problem.
It turned out that I had to Repair Disk with Disk Utility. I had visited a site earlier that had hijacked Safari and was telling me to call a number for emergency repairs, an obvious scam.
I followed the Disk Utility instructions to repair disk (including restarting with CMD-R pressed). Another clue was that I tried to commit to git and Xcode said No Way, Jose.
Afterwards I was able to refactor and commit changes as if nothing ever happened. I hope this helps someone else as a possible cause to investigate.
