So I am very new to Swift and XCode. I am trying to use an external library called JJFloatingActionButton the projects build fine but when I try run it on an emulator I get:
dyld: Library not loaded: #rpath/JJFloatingActionButton.framework/JJFloatingActionButton
Referenced from: /Users/mkangwa/Library/Developer/CoreSimulator/Devices/

Reason: image not found
Now of course I know you can't come ask a question like this on StackOverflow without researching and trying to find a solution yourself, so thats what I've been doing for the past few hours I have been looking at what was causing this, I started thinking that maybe it was the library it's self so this one is the third or fourth I've tried till I came across a few posts on SO that were about this issue.
Most people fixed this by just putting the Framework into the Embedded Binaries in the targets General Settings. And I tried this but I now receive a log:
I also get a Dependancy Analysis Warning:
I don't know much about these types or warning and errors but it's saying that it can't find the file which is pretty self explanatory but when I am adding the file to Embedded Binaries it shows the framework file there
What I often do when I have problems with cocoapods is remove cocoapods from the project and reinstall it.
You could use pod deintegrate (https://github.com/CocoaPods/cocoapods-deintegrate) to remove it and then a pod install to reinstall.
So it took a day and a half to work this out but I have finally got it and I can carry on with my project.
Problem:
The problem in my particular case (because other methods seemed to have worked for people trying to achieve the same thing) that the reason my project wouldn't build and was throwing Build Time errors was because after adding the Framework to Embedded Binaries it was also adding it to Embed Frameworks in my targets Build Phases. This then, I believe, caused the compiler to try and build it twice hence the Multiple Build Commands error
Solution:
So the errors I kept getting where saying No such file or directory above it was saying Multiple build commands for output file and what I did to fix this I went to Build Phases in my target settings and deleted the framework from Embedded Frameworks but made sure it was still under [CP] Embed Pods Frameworks.
in my case I was have to make framework "embed & sign" in stead of "don't embed"
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
Hello I'm trying to build MailCore framework since two days... it's giving too many errors.
first it was giving 'config.h no such file' error. I downloaded another copy of MailCore and this one is giving two errors
1-target specifies product type 'com.apple.product-type.framework', but there's no such product type for the 'iphonesimulator' platform
2-Internal error occurred while creating dependency graph: ASSERTION FAILURE in /SourceCache/IDEXcode3ProjectSupport/IDEXcode3ProjectSupport-928/Xcode3Sources/XcodeIDE/Frameworks/DevToolsBase/pbxcore/Target.subproj/PBXTargetBuildContext.m:1966
please help me out.. I'm sick of it.
Thanks in advance.
I solved the issue by implementing the instructions exactly what is told here... http://libmailcore.com/...
no need to build framework... just include the files in your project as told by the link I've mentioned and you are done...
I can only speak to that "config.h" error:
Turns out you have to have MailCore in a folder with no spaces in the directory path.
See: https://github.com/mronge/MailCore/issues/35
I moved the folder to /Users/bill/Documents/dev/lib/MailCore and was able to build the project there. Leaving MailCore at that location, I dragged the MailCore.xcodeproj file into my project (located elsewhere on the hard drive) and was able to compile my project.
Would be nice if someone would add this as a warning to to the directions here
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.
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
