clang: error: linker command failed with exit code 1 (use -v to see invocation)

I've tried followings but no result :(

1) Clean and build

2) Enable bitcode: no

3) Valid architectures: delete arm7 and arm64, only left armv7

4) pod update

Any help?

Answer 1

I’ve created another project and copy all the old files into the new one. I’ve installed the same pods. Nothing changed from the old project. Now it works.

Answer 2

Please share your pod list, some of them have double info.plsit files that causes this problem in xcode 9, plus, try to go to "build pashes" and remove your info.plist from there, and one more question. what device and ios are you using?

Answer 3

Have you tried clearing your DerivedData folder? It is located in /Users/Your_User/Library/Developer/Xcode/DerivedData. After, just recompile your app, and see if it works.

You should also look for any duplicate files, SDKs, classes, variables, etc.

If this does not work and you are using Cocoa pods, you can run pod cache clear and then pod install to reinstall your pods.

Finally, if this doesn't work, and you have source control enabled, you can try to remove your local copy and then fetch your project again.
