When I try to build ios my react-native project, Xcode is showing that error message
ld: file not found: /Users/macbookpro/Library/Developer/Xcode/DerivedData/myapp-ffcnutcqdnueacfosafqnwvmdnhh/Build/Products/Debug-iphonesimulator/myapp.app/myapp clang: error: linker command failed with exit code 1 (use -v to see invocation)
I already tried that solution: https://stackoverflow.com/a/27496743/9238414. it's not ok since I didn't change my target name before.
it's frustrating. anyway, I solved the issue by creating a new scheme,
it worked for me.
getting the following error.
i did have duplicate names for a var but i have now changed these and the error is still there how can I fix this?
duplicate symbol _main in:
/Users/James/Library/Developer/Xcode/DerivedData/project2_18094969-dbsiivorqvjflcejayyqrobtrdwt/Build/Intermediates/project2_18094969.build/Debug-iphonesimulator/project2_18094969.build/Objects-normal/x86_64/main.o
/Users/James/Library/Developer/Xcode/DerivedData/project2_18094969-dbsiivorqvjflcejayyqrobtrdwt/Build/Intermediates/project2_18094969.build/Debug-iphonesimulator/project2_18094969.build/Objects-normal/x86_64/AppDelegate.o
ld: 1 duplicate symbol for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Please check whether you have deleted the names which has been already connected to outlet. If so, remove the outlet. This scenario will throw linker error. I had experienced these type of error.
That error may contains many different errors not only on your code. Some times on your files. Try to check the files in your project(if deleted that is in the code), or check the upper part of the error because it'll give the source of error.
> but i have now changed these and the error is still there how can I fix this?
Trash your derived data and do a clean build, this will solve the issue.
Path: ~/Library/Developer/Xcode/DerivedData
Clean your xcode project and try to build again, if you have already removed duplicacy in code.
I am trying to create archive of my project and everytime i am getting this error:
ld: can't open output file for writing: /Users/ranbeerhora/Documents/KicksendRepo/KickSend/trunk/KicksendiOSSwift /Build/Intermediates/ArchiveIntermediates/KickSend/IntermediateBuildFilesPath/KickSend.build/Release-iphoneos/KickSend.build/Objects-normal/arm64/KickSend, errno=21 for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
i have tried different things but none of the solution works.
I got the answer.I was not giving path of the objective-c bridging header file in the build setting, when i gave the file path it worked.
Explanation:
xcode was not able to open output file for writing because it was not able to access that file since the path was not given when i gave the path xcode found the file and i was able to create the archive.
I have created the project, when I am trying to run the project I get the following error and build fails.
ld: file not found: /Users/mohammad/Library/Developer/Xcode/DerivedData/SPA-clncipsgigcqmgaourubdrurgfyz/Build/Products/Debug-iphonesimulator/SPA.app/SPA
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Any suggestions.

/Library/Developer/Xcode/DerivedData

I was getting same error and I got it resolved this way.
Try to set Build Active Architecture Only to NO for 'Pods' project and
your app's target
Make sure that you are using the .xcworkspace file
Don't use .xcodeproj file even if it run the app successfully on your device. It wouldn't help you to make a general build.
