Theoretically there is somewhere to get older versions of development software so I could reinstall XCode 14.2 but I can't find it on the developer site. Does anyone know how to do this?

XCBBuildService is crashing. I saved the report as text but this site won't let me attach the file. The error reported in the file is: Error Code: 0x00000004 (no mapping for user data read). I'm hoping to get some help here because I'm not getting a response from Developer Technical Support.

Finally I decided to do the really difficult thing. I created a new XCode multiple document project and began to carefully add the source files to it. I got about half way through before XCode failed to add a .h file to the project. After doing this several times it added the .h file but it won't build because it generates the dreaded Expected identifier or '(' error at the first ocurance of any text in the file after the compiler directives. This is HORRIFYING.

I got a version of XCode from December when I installed this version using Time Machine. This doesn't help. Since the analyzer thinks that the .h files aren't in the scheme I deleted the scheme and built a new one. No help either.

After spending a great deal of time trying to diagnose and fix this problem I have been able to ascertain that: On June 15th XCBBuildService, a component of XCode, crashed. This killed Xcode. Now I can’t build my projects because even though the header files in the projects are installed correctly and have the correct target membership, the analyzer thinks that they are not in the build scheme of the project. When I try to build a project Xcode will fail to build as soon as it encounters a header file. It will report the spurious error: Expected identifier or ‘(‘ as soon as there is any text after any #includes. This is function prototypes but also statements like enum. Then it will report an error of undefined functions in a file where the prototypes are in the .h file that it now can’t build. I can’t install the latest version of Xcode because I’m using an Intel iMac. How in the world can I possibly fix this?

More bad news: It isn't just the one .h file. If I select any .h file and use Product>Perform Action>Compile File I get an error 'headerFileName.h' is not a member of any targets in the current scheme that build for running. So it appears that the target is broken and doesn't know it has any headers. If I delete the target and re-build the project will XCode create a new target? Maybe one that works?

I filed a DTS technical service request.

After I delete the derived data, XCode will re-index and rebuild the project but it is still dead. I thought about upgrading to the newer version of XCode but it can't be installed on my Intel iMac. Some projects still work but the two really important ones are dead. Unless someone has some idea of how to solve this problem I can't develop software for the Mac.

Searching for XCBBuildService I found several posts on Stack overflow from people with similar problems. They solved them by deleting the derived data in their ~/Library/Developer/DerivedData folder. Would this help? I can cd the directory to this with the terminal command ~/Library/Developer/XCode but it looks like I can't do anything with the contents of the DerivedData directory: Permission denied. I could open the DerivedData Directory in the Finder and delete the data. Should I do it?

Booting in safe mode didn't help. Disk First Aid thinks that everything is OK. EtreCheckPro found a suspicious problem: Yesterday XCBBuildService, a component of XCode, crashed. My best guess is that when this happened it killed my project. How would I fix this?

Things have gone from horrible to worse. Each time I build my project XCode is randomly deciding that one of the headers has the spurious "Expected identifier or '('" error and that the functions in the .c or .m file are undefined. Each time I build the project a different file is affected and there is a different number of errors. Also it has decided that it doesn't know what an enum declaration is. I got really desperate: I cleaned the build folder and closed XCode. I restarted my machine. The project was working yesterday so I restored yesterday's .xcodeproj file with Time Machine. No, XCode has completely failed and it's getting worse. The version of XCode I'm using (14.2 (14C18)) was installed in December. Is there a newer one?

Now XCode has completely lost its mind and is randomly reporting the spurious Expected identifier error all over the place in files that include a header.

Thanks, this seems to fix it. Also locking the field to its parent view and making it un-resizeable with the auto-resizing pane seems to help. I'll try to mark this as solved.

I can add layout constraints using the Editor>Resolve Auto Layout Issues>Add Missing Constraints. This works for SOME NSViews but in others with more interface items it creates a huge list of errors.

Also I should mention that in the build settings "Interface Builder XIB Compiler Options" I can set Show Errors, Show Notices and Show Warnings to NO but XCode still reports these warnings. Also only some NSText fields generate this warning even though they are all configured the same except for their sizes and locations.
