Unsolvable linker error when compiling app in Xcode

Question

I've been working on an app for some time now and it had been giving me trouble compiling on an iPhone. Recently, it stopped compiling even on the simulator. I've browsed stack overflow and other websites for answers but I can't seem to find anything that resolves the issue. Below is the error I'm getting.

I've restored an earlier version of the entire app to see if that fixed the problem but it didn't seem to make any difference. I'm still getting the same error.

Can anyone help?

Just clean your Project & simulator or reset your simulator try it — Mayank Patel, Jan 20 '16 at 08:29
have you clean your project in Xcode ? goto Products -> Clean — Mayank Patel, Jan 20 '16 at 08:32

There is no error there, that's just the linker commandline and environment setup. What's the actual error? — damian, Jan 20 '16 at 08:42
@damian the code below says ld: library not found for -lPods clang: error: linker command failed with exit code 1 (use -v to see invocation) — Beau Harper, Jan 20 '16 at 08:44
Looks like this is a duplicate of http://stackoverflow.com/questions/9863836/library-not-found-for-lpods — damian, Jan 20 '16 at 08:49
@damian I took a look at that question and tried all of the solutions provided but came up empty-handed — Beau Harper, Jan 20 '16 at 08:56

After further review and fiddling, and after reviewing a similar question referenced by @damian, it seems that the solution was this:

I separated the app and the test targets in the Podfile by using

target :App do
…
end

target :AppTests do
…
end

This resulted in two new products libPods-App.a and libPods-AppTests.a, respectively and they made the previous product libPods.a obsolete. I had to remove this product from the Link Binary With Libraries Section of the Build Phases configuration of both targets.

Thanks for the input everyone!

Awesome. Good job hunting that one down. – Stephen Paul Jan 21 '16 at 09:16 — Stephen Paul, Jan 21 '16 at 09:16

Try deleting your Derived Data folder, restarting Xcode and and running the project again. Go to Window -> Projects and navigate to your project. There should be mention of your derived data folder. Press Delete, restart Xcode and try building it again. See if that kicks it back into high gear again.

I deleted all derived data both through Xcode and through terminal and I'm still getting the same error. – Beau Harper Jan 20 '16 at 08:41
