Linker command failed with exit code 1 error in Xcode project - iphone

I was working on my project and suddenly after editing the code and compiling gave this error:
ld: warning: directory not found for option '-
L/Users/mani/Documents/Classes/Twitter+OAuth/Libraries & Headers' ld:
duplicate symbol _OBJC_CLASS_$_playSiew in
/Users/mani/Library/Developer/Xcode/DerivedData/learn-aktrtiwswclovoatyweyquoxmypa/Build/Intermediates/learn.build/Debug-iphonesimulator/learn.build/Objects-normal/i386/playSiew.o
and
/Users/mani/Library/Developer/Xcode/DerivedData/learn-aktrtiwswclovoatyweyquoxmypa/Build/Intermediates/learn.build/Debug-iphonesimulator/learn.build/Objects-normal/i386/Thumb.o
for architecture i386 clang: error: linker command failed with exit
code 1 (use -v to see invocation)
I never touched the project settings, just edited the code.
What's more strange is that I took out last revised code from svn but still I got the the same error.

You may be accidentally #import'ing a .m file instead of a .h. Use Cmd+Shift+F and search for ".m" (without quotes). It will most likely lie in one of the classes mentioned in the warning. If not, clean and run again.

I was also having same issue and I did following and issue is gone.
Go to Product -> Clean and re-run the project.
I hope it might be useful for some other developers.

After running into this problem a few minutes ago (yes, I know it's been 7 months since the original thread) I found that the root of my issue was due to me dragging & dropping files into my project within XCode instead of right-clicking and choosing Add Files to Project.

Check playSiew.m is in Compile Sources section. isn't it?
You can find Compile Sources section follow this step
Select YourProjectName
Select TARGETS
Select Build Phases
If don't have playSiew.m in this section . You must to add it to this section.

As I said the problem wasn't the code but some settings. So what I did was copying the code from my friends' Mac (it was working fine), and installed a fresh copy of the project to my Mac. It worked.

I was importing a library in a test case which I had specified in my pod file for the main target but not for the test target.

I also got this error because I had accidentally included two versions of the same source file. Deleted the wrong one and the problem went away...

If you're working in Unity and export to iOS and you are using a plugin, go to Xcode Build Settings and set ENABLE BITCODE = NO. I'm guessing this might apply to other situations as well

Faced similar issue, while running the code on a simulator, tried all the above mentioned options, still got the same error. Tried connecting the iOS device and build the code, it worked for us. This can be a quick workaround.

the same error i faced. so, i just removed reference of that classes which are generating the errors and than again gave reference and the error was gone...
as D80Buckeye says there should be problem of dragging and dropping files instead of Clicking on "Add Files"

In case this comes in useful for anyone else--I just had this same error, and turns out the cause was initializing a variable in my header file rather than in the main file.

I just encountered the same error. If you are using embedded Libraries, make sure your Deployment Target is set to iOS 8.0 or higher.

you only need to add the following framework: quartzcore.framework

The only way we can get past this bug on our project is to do a Clean and then build for iPad Retina. After that it will build successfully for any device. Weird.

In my case i have add reference of FacebookLoginSDK framework but forget to give search path in build setting. After removing its reference everything was fine.
So conclusion is if you are adding any external framework be careful.

If this happens to you with CoreData generated classes, combine the +CoreDataProperties and +CoreDataClass into the +CoreDataProperties class and delete the +CoreDataClass. Make sure to search Derived Data for leftovers of the +CoreDataClass. Even after deleting the Derived Data and cleaning I sometimes had Xcode just generate the +CoreDataClass again and again. Deleting it manually in Finder and then re-bulding helped me solve this.

try this, go to Target -> Build Settings,then search these three as following,
GCC_NO_COMMON_BLOCKS,
CLANG_WARN_INFINITE_RECURSION,
CLANG_WARN_SUSPICIOUS_MOVE,
set NO to each value then clean and build.

I tried several of the answers listed but none worked for me.
I got the error after updating XCode (while it was still open which may have contributed to the problem)
First, I deleted my Derived Data folder:
XCode => Preferences => Locations => Double Click on arrow next to path indicating where the Derived Data folder is.
Then "Move to Trash"
I don't think that's what the problem was, but it's amazing how many times this has been an issue for me working on different problems.
Second, I 'Quit' the simulator.
Third, I 'Quit' XCode.
Fourth, I opened up my project in XCode again and then did a Clean and Build (found in the Product menu)
Fifth, I ran my project and it worked fine

Cleaning the project not works for me.
Restart the Xcode works for me...

For me it was different. I had the same error when I removed a Pod and solved it by removing this pod from the Other Linker Flags in the Build Settings
then clean your project [Product > Clean] and rebuild

Go to general and linked frameworks and libraries in xcode and remove all the files there.

'Convert to latest Swift Syntax' breaks the build even when there are no changes

My project is in objective-c with just one tableviewcontroller in swift. I downloaded the Xcode-beta today which prompted me to 'Convert to latest Swift Syntax'. After I follow the steps it shows me that there are no changes. I do not see any changes in the proj file either but it has errors. Please note that I do not see the errors when I choose not to covert to latest swift syntax - the app builds and runs fine in this case.
Any idea why it is breaking?
Here are the errors -
cannot parse the debug map for "app name" No such file or directory
clang: error: linker command failed with exit code 1 (use -v to see invocation)
the other errors are that it is not able to find the swift file. The swift class was initiated in the objective-c class.
Switch ENABLE_BITCODE to NO in project build settings helped me.
Product -> Clean helped in my case.
I had an issue similar to this, and I fixed it by changing the build phases/ compile sources in the project :
I had added in new sources that needed to be compiled earlier in the project, and after i deleted the files, when I tried to build the project it said it was missing the files that I deleted. After deleting a few of the build phases that appeared as though they were not the default build phases, it worked fine.
I found that there were a default of 4 compile sources.
Also, using Ctrl+Shift+K will clean your project, which helped me another time with an error like this.
I was having the same issue, and none of the above answers helped. Apparently, my issue was I had an import using a .m file instead of a .h file.
The easy way to find and fix these would be Find > Find in Project... and searching for #import.*m and changing them to the appropriate .h file

Xcode upgrade: PBXContainerItemProxy missing containerPortal key

I just upgraded my Xcode, now when I try to open my project, I get this error:
Project /Users/xxx/xxxx/xxxxx/xxxxxx/xxxxxxxx.xcodeproj cannot be opened: PBXContainerItemProxy (xxxxxxxxxxxxxxxxx) is missing a containerPortal key
I have searched the web and stackoverflow, but cannot get anything relevent to come up at all regarding this.
I do have Three20 as part of my project, I don't know if that matters. I just upgraded to xcode 4.4.1
Thanks for any insight.
-D
the project icon which we see i.e projectname.xcodeproj, is actually a directory, you do this
1. in terminal do cd yourproject.xcodeproj
2.ls
3.vi project.pbxproj
4. scroll down till /* Begin PBXContainerItemProxy section */
5.there you will see all sections check for the section which is missing a portal key edit it and save it :wq it will work
in image if you see the first section is missing container portal key.just pic it from other section and replace it..
it will work :D see this link
Now I should start with that I do not know the actual error, never seen it before, but I did find a reference to a "PBXContainerProxy"-error in this post (As soon as I add a project to XCode 4.0.2 it crashes) and thought you might try the solutions from there?
"Apparently this is due to the new version of XCodeProjects. I found a
work around by pre-compiling the library that was causing the issue
and then using the linker to link to the .a file. I also had to copy
the .a library into the DerivedData path.
The real solution was to remove the project and replace it with an
updated project for the new version of XCode."
Hope that helps somewhat :)
Never saw that error either, but if you're upgrading directly from XCode 3.X I'd suggest you to go to https://developer.apple.com/downloads/index.action?name=Xcode
and download/install a previous version of Xcode somewhere else. (You can have several different copies installed on your machine, just google it if you don't know how but just remember to use xcode-select to pick the one you want to use). Repeat with all the versions back to 4.0.1 until (hopefully) it works. I know it's tedious but it might help.
If it does, validate the project settings and try to open it with 4.4.1. That should work.
Good luck

RestKit/RestKit.h file not found error - version 0.10.0

I am losing my hair in my attempts to get RestKit to build and work. I get the dreaded "Lexical or Preprocessor issue: RestKit/RestKit.h file not found" message. I use Xcode 4.2 & my project is for iOS.
Earlier, I had debug mode working perfectly with RestKit 0.9.0. Then I ran into issues while trying to archive. After reading this forum and attempting some solutions, I decided to upgrade to 0.10.0 with hopes that it will solve the issue.
Now, my project is not even building in debug mode and I get the same RestKit/RestKit.h file not found error.
I have this under Header search path: "$(BUILT_PRODUCTS_DIR)/../../Headers". Can you please suggest (for 0.10.0 version):
1) Where should the physical location of RestKit be? (It may not matter, but which one worked for you - with hopes that I can mirror your setting)
2) I tried to point my header search path to "/Developer/Library/RestKit-RestKit-69adee9/" and later to "/Developer/Library/RestKit-RestKit-69adee9/Build"
Throughly confused and frustrated..
EDIT1: After several hours, I gave up. Nuked my project. Created a fresh project. Re-created the files (copy paste from prev project). Now "RestKit not found" error is gone! But now, I am getting this other error:
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_RKObjectMapping", referenced from:
objc-class-ref in myclassname1.o
"_OBJC_CLASS_$_RKObjectManager", referenced from:
objc-class-ref in myclassname2.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I checked & made sure that I did NOT add RestKit.framework... I've no idea why the clang error is happening now
EDIT2: The libRestKit.a was red. It is OK according to https://github.com/RestKit/RestKit/wiki/Installation-Troubleshooting Just for the heck of it, I removed all the linked dependencies. Removed the "Other linker flags". Closed & reopened Xcode. Put them all back. That error is gone. Maybe I missed a framework which resulted in clang error. But it is highly unlikely for I checked & double checked. It works now.
It builds & archives on debug mode. I haven't tried the distribution mode yet.
EDIT3: Apple approved my app in the first go & it is live! I still do not know what caused the issue here. Nuking an existing project & creating a new one & copying over the old files (& periodically checking if build goes through) cannot be a solution. So I am leaving this question open.
I think I can shed some light on this.
When you upgrade to 0.10.0, you change your header search paths to "$(BUILT_PRODUCTS_DIR)/../../Headers", right?
The install guide only says to do this for the project settings. However in many cases, mine included, you'll need to also update them for the target settings as well.
The target settings will still have the old header search paths, and for whatever reason decide not to inherit from the project settings.
Mind you - its a total hack - but it got my project running.
Assuming that you've already followed the installation steps from the RestKit Github
https://github.com/RestKit/RestKit/blob/master/README.md#quick-start-aka-tldr
In the RestKit target, goto Build Phases. Under the Copy Headers dropdown, move all of the header files from "Project" to "Public".
Clean, Build, Run.
Solution I found was not to copy and past the "$(BUILT_PRODUCTS_DIR)/../../Headers" to your target's Header Search Paths.
After five hours I deleted the copy and pasted " and manually typed them in and it worked.
I recently played around with upgrading from RestKit 0.9.3 to 0.10.0 and had the same thing. Did you delete the RestKit/build directory? This contains a copy of the .h files and is created as part of the build process when building 0.9.x. Doing Product -> Clean doesn't seem to delete these files. 0.10.0 doesn't seem to create this build directory. I suspect that your build errors are due to those files still being picked up.
Also, to answer your question fully, I keep RestKit files in:
(project dir)/Frameworks/RestKit
This is a git submodule so it contains a clone of the RestKit git repo at a particular revision.
And the header search path is:
$(BUILT_PRODUCTS_DIR)/../../Headers
The header search path for 0.9.3 was:
$(SOURCE_ROOT)/RestKit/Build
I found this guide helpful (maybe this is what you are already following): https://github.com/RestKit/RestKit/wiki/Installing-RestKit-in-Xcode-4.x
and note the section about only having libRestKit.a in the project for the latest RestKit versions where earlier versions had all of:
libRestKitNetwork.a
libRestKitObjectMapping.a
libRestKitSupport.a
libRestKitJSONParserJSONKit.a
libRestKitXMLParserLibxml.a
libRestKitCoreData.a
If you have all of these, delete them from your project.
Been fighting with the same issue for the past few hours. What finally worked for me (and I'm not saying this is a definite fix, but at least it's something to try).
Delete RestKit from your Project
Close your project
Move the RestKit folder next to your main xcodeproject
Open the RestKit project and build it
Close the RestKit project
Open your project, and re-import the RestKit project into your xcodeproject
Fix the Dependencies and Linkings in the target settings
Add the "$(BUILT_PRODUCTS_DIR)/../../Headers" search path to BOTH the project settings and the target settings. (it only worked for me when they were listed in both).
This last step might be all that's necessary to fix it, but since I too was pulling my hair out over this, I tried a lot of different solutions and didn't want to assume that this last step was the sole reason it fixed itself.
(and my setup is XCode 4.3.2 and OS X 10.7.3)
After spending 2 days on this same error and navigating to every possibile google result I finally got it!
It's not due to Derived Data settings, those are fine already in XCode 4.3.2.
The problem is that you are doing a #import "RKObjectMapping.h" or some other include.
Instead use #class RKObjectMapping or if you really nead the .h use <RestKit/RKObjectMapping.h>
I went with #class since I just need to compile...
Hope this help!
Had this problem too. It would build and run just fine on simulator, but would not archive. Here's where I went wrong...
I did this:
#import "RestKit.h"
Rather than the correct way:
#import <RestKit/RestKit.h>
I had the exact same error today. All our code is in a github repo and the restkit folder is ignored so none of the restkit files were in there. Now, when xcode opens the project and finds stuff missing, it assumes all hell broke loose. So, deleted the folder, re cloned it and then grabbed a fresh copy of the restkit and threw it in there and voila, everything worked.
I found that I need to manually build the RestKit target for the header files to be copied into the build directory. Apparently the master project build does not reliably run the subproject build?
So, my steps for fixing this issue:
Select the RestKit run target
Build
Make sure the header search path was set on all target (apparently on project itself is not enough)
Build main project
Had a very similar problem. It turned out to be I had accidentally added the build setting to "User Header Search Paths" rather than "Header Search Paths".
My solution:
When adding "$(BUILT_PRODUCTS_DIR)/../../Headers" to
Targets -> Build Settings -> Search Paths -> Header Search paths,
the value was not set.
Instead the value has have been set up to User Header Search Paths.
So you double click to Header Search Paths, some pane with lines appear, you click + down left, paste that string there, click somewhere else to dismiss the window and... nothing.
The Header Search Paths didnt get updated but User Header Search Path did.
?!!!
So you click on the disclosure button on Header Search Paths.
Click + sign right of the attribute and add the value...
Here's a common mistake that'll make you want to slap yourself after you fix it.
Yes, you definitely do want to add "$(BUILT_PRODUCTS_DIR)/../../Headers" to your target's Header Search Paths, but don't forget to include the quotes!
I'm talking about the quotes that are before $(BUILT and after _DIR)/../../Headers
If your build configuration has a space in the name (e.g. mine is 'Ad Hoc') and you've just added $(BUILT_PRODUCTS_DIR)/../../Headers without the leading and trailing quotes, you may end up getting the "Lexical or Preprocessor issue: RestKit/RestKit.h file not found" problem.
This is a problem that I don't think has enough answers for this problem, because if you have this problem it feels like there is nothing to be done! After trying all of the proposed solutions (none of them worked). I finally found the problem
The problem was that one of my folders had a space in it. Don't use spaces in your source folder names!
Used to be : (/Xcode projects/basicRestkit etc...) -- lots of pain and suffering
changed to : (/projects/basicRestkit) -- lots of rejoicing
This caused the header search paths not to work, and therefore not to find the files. There may very well be a way to use alter the header search paths to find your files even with spaces.
This might not help you, but it very well could. Good luck.
For me only these steps works. Check here Hope this will help.

Three20.h file not found when building with xcodebuild

I build my project(include subproject Three20) successfully using xcode GUI,but when I use xcodebuild,it failed with this below:
/Users/***/MyProject/Classes/ComposeSMSViewController.h:14:9: fatal error: 'Three20/Three20.h' file not found [1] #import <Three20/Three20.h> 1 error generated.
my Header Search Paths are $(BUILT_PRODUCTS_DIR)/../three20 and $(BUILT_PRODUCTS_DIR)/../../three20 and Classes/Three20/Build/Products/three20
That works on GUI building but failed on xcodebuild.
How can I solve this? Thanks
I think you should restart three20's install , it need several steps and make sure it's without mistake. Best regards. It may help you: http://three20.info/article/2011-03-10-Xcode4-Support
If it still doesn´t work (and an error like "Three20.h file not found" is shown), try setting "Skip Install" to "Yes" for all of the Three20 dependencies and projects in your app (except your main project): graphically . This onle creates an .ipa for your project, but not for your three20 projects.
I resolved this issue today by accident. I tried all the solutions I found online and it didn't work. I was pretty confident that the problem was within xcode because the app built fine on my boss's machine. Turns out my scheme name didn't match my target name. This was a result of duplicating a target, which automatically named my scheme to "myapp copy". When I matched the scheme name to the target name, everything worked fine and the three20.h file was found. Hope this helps anyone with similar circumstances.
Product-> Manage Schemes... and rename the file

refactor function error - "is not part of the build phase of any targets in the Xcode 3 projects in this workspace and so can't be refactored"

Trying to rename a function's name via the refactor->rename button in a categoriy's .h file in XCode 4.1 I'm getting this error: (error and body)
UINavigationController+ZG.h is not part of the build phase of any targets in the Xcode 3 projects in this workspace and so can’t be refactored.
Add the file to the build phase of a target in an Xcode 3 project in this workspace, or make a selection in another file.
Not sure what it wants and why it's saying something about xcode 3 when i don't have any xcode 3 projects or anything like that.
I had this issue today on a project which don't use workspace at all.
I couldn't get why Xcode behave wired. Auto complete worked, but return some really unrelevant results as my FAMILY NAME (?!) for a class I was working on.
I found it to be a bug in Xcode 4.1 under OS X 10.7.1 along side with other issues i had.
When I reopen my project, the message was gone, refactoring worked as expected and auto-completing worked as well.
September 2013 Update:
It seems that this bug is happening also on Xcode 5 & 10.8.5.
Restarting Xcode did not fix this for me (although it does normally fix a lot of things). I also didn't like the idea of File >> Save As Workspace. As the workspace should already be in my .xcodeproj file, so I didn't want another one. I found another solution that fixed it for me: Window >> Organiser and then Delete Derived Data for my project. Found it mentioned in this other question.
I was able to get past this error by choosing File >> Save As Workspace.
For me personally it was a combination of things.
Deleted derived data from Organizer > projects. (Didn't work after this step)
Restarted Xcode. (Worked after this step)
I have just run into this issue as well. I found that running:
Product->Clean
Fixed the problem, and I can now use refractor again.
I replaced some dead values in project.xcworkspace (Show Package Contents on your Xcode project file) and the problem went away
Have you ever deleted .xcworkspace in Finder? Although the file will be auto-generated by Xcode again, yet its content will be changed. I think that causes your problem.
I saw a post recommends to delete .xcworkspace for the purpose of enhancing build speed. Well, mind the catch.
