Mysterious errors is Xcode? - ios

I wanted to reach my project folder's directory through the terminal so to make things a little easier, I simply moved the project folder onto my desktop, when doing this i was presented with this prompt:
I then pressed re-save and was presented with this prompt:
After this i moved the folder back in its original place, but when i attempt to build the app i get the following 30 Apple Mach-O Linker Error errors:
I attempted a clean/clean build folder... but no success. Now I have the parse and AWS SDK frameworks installed within my project, so I completely removed them both, re-inserted them, cleaned the project, build and still the same 30 errors. What seems to be the issue? I may also add i mistakenly dragged the project folder onto the desktop and out of its original folder while the app was still running. If that means anything. What can I do?

Maybe you have an absolute path somewhere in your project's or target's settings, or a relative path pointing to a dependency outside the folder you moved. You could try to look for parts of the previous path in the settings. Alternatively with text search in a terminal, you can try something like this (in this case from the project's root directory):
grep -r "mypath/mypath" myproject.xcodeproj/project.pbxproj
Also to shed a bit more light into the issue try dragging the project back to the original folder. Is the issue fixed? If yes it's definitely a path problem.

Xcode not able to find project file

In my Xcode project there are other projects linked but somehow its not able to read the sub project.
As you can see MobiResourceManager.xcodeproj is shown in red. And thus the classes which uses headers inside it gives error. But I am not able to understand why its not able to show the project. Sometimes it doesn't show MobiResourceManager.xcodeproj in red but even then the classes using its header gives error of HeaderName.h not found.
The problem that I am facing is happening only in my system. I tried cleaning, deleting-installing Xcode, cloning the repository again but nothing works.
All the project file shown in the screen shot are sub project inside one main project.
Probably that red file was removed or moved somewhere else. Open Finder, locate the missing xcodeproj, then remove this one in Xcode and drag&drop the located one. If that red xcodeproj is inside your repository (what I suspect) then do not select to copy it to the destination.
If you cannot locate that red file, it means it is not added to the repository. For example, it could mean that you need to install it with git submodules or another way - depends on the project configuration.
Are you using the workspace? if yes then please open that file not xcode project file

DropboxSDK.framework file not found after relaunching Xcode

I am using the DropboxSDK.framework in a project of mine.
I have everything setup and working fine. However, every time I quite Xcode and open it again at a later point I get the error below:
Which is weird because I can see that the framework is in the project and nothing (that I know of) has changed since the last time I had the project open and working.
The way I make the error go away is to:
Right click on the DropboxSDK.framework in my project --> Delete --> Remove Reference.
In my project's Build Settings under Search Paths I remove the path that is under Framework Search Paths (the highlighted selection in the image below).
Then I clean my project SHIFT + CMD + K
Lastly, I click File --> Add files to my project, navigate to the DropboxSDK.framework file which I previously removed reference to and add it back to my project.
Then I build my project again and the error goes away and will remain gone until I quite Xcode and open it again.
Has anyone else ever encountered this happening and fixed it?
Or have any suggestions I could try to fix it? I'm using Xcode V5.1.1
Let me know if there's anything I can clarify. Thank you!
$(SRCROOT)/Application_Folder
Application_Folder is the name of the folder where your whole code other resources resides
Insert above line in Header Search Paths
I had a random thought sparked by Indrajeet's answer that solved my problem.
When a new project is created in Xcode a project folder is created. In that folder there is another folder with the same name as your project, a .xcodeproj file with your project's name and a yourProjectNameTests folder.
Visually like this.
Application_Name --> Application_Name
Application_Name.xcodeproj
Application_NameTests
When I was having the error I described above the DropboxSDK.framework and it's accompanying files were stored here in this folder:
After removing all references to the DropboxSDK.framework in my project I decided to move the DropboxSDK.framwork and it's accompanying files one folder level up to the main Application_Name folder here:
Once I did this, I clicked File --> Add files to my project, navigated to the DropboxSDK.framework file, now one folder level up and added it to my project.
After building no error was thrown. I restarted Xcode and tried again to make sure; still no error. Rebooted my computer to be truly sure... still no error!
I was having the sane problem and just found the answer by chance!
It happens when you create your project name with SPACES between the letters. Somehow it makes XCode crazy when searching for the frameworks.
So if want to create a project called "This is My Project Name", call it "This_is_My_Project_Name" and the frameworks will be found every time. It worked with me.

move an xcode 4.5.1 project to different folder

I have created a rather large application in xcode and wish to move the files somewhere else on my computer.
Could this process be as simple as dragging the project folder to a different place in finder or will something mess up?
Moving the .xcodeproj files will not cause any issues as long as xcode is closed when you migrate the files and you delete the old files.
When xcode is next launched, if you browse and open the proj file from the new directory, all the references will be set to the correct destinations
on a side note it always pays to keep the old files in a .old folder when migrating projects to avoid issues.
As long as the files are kept in their respective folders, next time you run a build in xcode, the references to the new directory the proj file is in will be updated.
As another side note, i just tried to do this and it messed up for me. Typically, any references will switch over, but i had a linker error: ld. it was trying to link to an external library that was contained within the old folder. i had to go to build settings->search paths->library search paths and change that to the new folder location. that worked for me.

iOS build failure; /bin/sh No such file or directory

I was working on my application and then out of no where, I get this build error and can't figure out why it won't go away. Obviously it thinks I am missing a script of some sort. Anybody else know why? I am using Xcode 4.5.1.
/bin/sh:
/Users/JonErickson/Library/Developer/Xcode/DerivedData/FireCom-cygbnsedlgybvdewalvvmzqeehlc/Build/Intermediates/FireCom.build/Debug-iphonesimulator/FireCom.build/Script-C8CC6BE415FAAB4C001BB67E.sh:
(null): bad interpreter: No such file or directory
Check for a potentially corrupt "run script" phase in your project's "build phases".
It should look something like this:
I had renamed my app, and got into this error. In various places, I changed the name but couldn't find at one spot .. - in Target's build setting file.
Cmd + Shift + F to find in whole project.
searched for old App name string.
Found places where old name was still stuck, updated it with new name.
I've encountered this a number of times because my DerivedData isn't current with my work. I've never understand the logic for when it does and does not keep track of changes I'm making... but since the script is trying to run from an archive in the derived data, you'll need to make sure the script is actually present. To do this, delete your derived data (or at least the directory containing your script) and then build again. Xcode will fill in the gap(s). You can get quick access to Derived Data by navigating to the File menu and then going to Project Settings (or Workspace Settings accordingly) and following the link to your finder. Just trash it.

Project ...xcodeproj cannot be opened because it is missing its project.pbxproj file

I was trying to merge branches and it resulted in the error "Unable to open project… cannot be opened because the project file cannot be parsed". I then tried to take the advice of other stackoverflow responses (namely to edit the file to remove the corruption), but was unable to edit the file. It appears that this is actually a directory, so maybe the structure of this changed with version 4.4 of xcode and since the response to Unable to open project... cannot be opened because the project file cannot be parsed was written.
I then tried to restore myProject.xcodeproj from my time machine backup. This does not work because it says that I don't have permission to access myProject.xcodeproj. I tried to change the permission of that directory, but that did not help.
I closed and reopened xcode. Now the error is:
Project ...xcodeproj cannot be opened because it is missing its project.pbxproj file.
How can I fix this problem in xcode version 4.4? Can it be restored from the previous snapshot or archive or version in xcode. Can it be restored with time machine. I would like to avoid rebuilding the entire project.
The simplest thing to do is probably to
Checkout myProject.xcodeproj from source control. This will contain the changes that were causing you to be in conflict last time.
Redo the project changes that you made since the last time you committed to source control
commit/push to source control.
In the future, when you get a conflict in the project file, take a look at myProject.xcodeproj/project.pbxproj. Often it's just new files in the project that have been added at the same place. In this case you just need to delete the conflict metadata and resolve the conflicted state.
In the end, what I had to do was
'cp -R ...TimeMachineBackup/myProject.xcodeproj ...myProjectArea/myProject.xcodeproj'
Then I had to do the following in myProjectArea:
git reset --merge
This allowed me to open the project and switch branches back to my main branch.
not a pleasant experience
Another way this can happen is if you've been using sudo for some reason with pods or the editor - if the file exists under yourApp.xcodeprojectroj directory but xcode is complaining it can't find it - Go to your project root and do:
sudo chown -R yourusername:staff ./*
For others looking at this issue, the cause in my case turned out to be, that the "conflict text" from a git merge had crept into the actual file:
<<<<<<< HEAD
F0FDA2D61B99EB80007DB99D /* Aptron-mCollegix.xcassets */,
=======
F08CFAAA1BC1E9EE00A5B6F5 /* Aptron-mCollegix.xcassets */,
>>>>>>> hotfix/Column_Text_Cut-off
opening the project.pbxproj in a text editor made the fix easy.
I found my own solution to this issue.
The cause of the bug is that the .xcodeproj file is missing its containing pbxproj file, right? This is usually present when you right click your .xcodeproj file and click 'Show Package Contents'. However, in your own case, it's been deleted, through some mistake or other of git versioning.
As you can't really generate a .pbxproj file, the solution I found was to go to the original project folder location, which I had used to create the repository. To be honest, you could probably simply create a new project also, as long as it has the same bundle identifier and such! As this project's xcodeproj file will correctly contain a .pbxproj file, replacing the files in the XCode environment with your own project's files will allow the .pbxproj file to update based on these files.
Therefore, after opening this original project folder (/new project folder), in the XCode environment, I then removed all the files within the project, and replaced them with the corresponding files from my project which I was unable to open the xcodeproj file of. I had to fix a few resulting bugs here and there, stuff involving build phases and such not lining up, given you've just copied in a bunch of new files. But after fixing a few small errors, the same project in this new location was eventually able to run no problem!
Finally, I took this successfully running version of the project, and copied in all the files, .xcodeproj file, project folder, test files and all, into the original repository location, deleting the files from the repository before hand to avoid confusing overwriting of files (you can cut and paste the old repository files to a new location if you want to be safe, and don't fancy deleting them!). Then open the project in XCode from the repository location, build and run it on your simulator/device to make sure everything lines up (and fix any small bugs you may need to), and voila! Your project is now able to be committed, pushed, and ran!
This isn't the cleanest solution, and you may have to do similar things across various branches if they've all been corrupted. However, if you don't have access to a Mac time machine, and the other solutions aren't working for you, this is possibly the most straight forward way of having a working .pbxproj file again!
Oh, and I removed the .pbxproj from my gitignore. I'm not sure if it's actually find to have it in your gitignore or not, but I'd recommend doing your own research on that subject, I'm not certain myself!
Good luck!
I was able to get this working without commandline stuff like this:
Go to Time Machine drive in Finder.
Navigate to desired backup.
Drag it to where I want it. This will complain about not having permission to access the .pbxproj
Right-click the xcodeproj you just dragged out, select "Show Contents".
Right-click the xcodeproj in the Time Machine backup folder, select "Show Contents".
Drag the .pbxproj you see inside to the destnation you just created with the drag in #3.
Now it should work.
It seems you can generate the file again with:
swift package generate-xcodeproj
although you could see this message:
warning: Xcode can open and build Swift Packages directly. 'generate-xcodeproj' is no longer needed and will be deprecated soon.
generated: ./BokenEngine.xcodeproj
with xcodebuild > 13.4.1:
xcodebuild -version
Xcode 13.4.1
Build version 13F100
If anyone wants to find the missing project.pbxproj file then try opening the .xcodeproj with some code editor and you will find the file there. And note that i had backup of my application in my other pc so i found that file there so you mist have backup of your project somewhere in order for this to work.
In my case the issue was that there were actually 2 folders with .xcodeproj suffix
The actual one was located in MyApp/MyApp.xcodeproj
Somehow another one with the same name MyApp.xcodeproj got added to root folder, with the following contents:
project.xcworkspace/contents.xcworkspacedata
project.xcworkspace/xcshareddata/IDEWorkspaceChecks.plist
So deleting this corrupt(?) xcodeproj solved the issue.
