Linker command failed with exit code 1; undefined symbols for architecture armv7s.

问题

This is a first time I've been trying to upload binary (new version of an iOS App, not a completely new app) to the iTunes store. When I attempt to create an archive, I receive three Apple Mach-o linker errors, which show up red in issue navigator.

This is what shows up:

ld: warning: ignoring file /Users/alinam/Library/Developer/Xcode/DerivedData/Latina_1-bklvousdwnrhhgenrxpftegwerkb/Build/Intermediates/ArchiveIntermediates/Latina 1/BuildProductsPath/Release-iphoneos/libCordova.a, file was built for archive which is not the architecture being linked (armv7s): /Users/alinam/Library/Developer/Xcode/DerivedData/Latina_1-bklvousdwnrhhgenrxpftegwerkb/Build/Intermediates/ArchiveIntermediates/Latina 1/BuildProductsPath/Release-iphoneos/libCordova.a
Undefined symbols for architecture armv7s:

  _OBJC_METACLASS_$_MainViewController in MainViewController.o
"_OBJC_CLASS_$_CDVViewController", referenced from:
  _OBJC_CLASS_$_MainViewController in MainViewController.o`


ld: symbol(s) not found for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)`

In one of the existing discussions I read that it might have something to do with linking binary with libraries.

Well, under Build Phases -> Link Binary With Libraries the libCordova.a shows up red (missing?).

If so, how and where do I get it and what do I do with it then?

Update:

I resolved the issue of not being able to archive the app by removing armv7s and arm64 (and leaving only armv7) in the app's Build Settings -> Architectures -> Valid Architectures.

Now it looks like this.

I've left everything as it was under CordovaLib.xcodeproj -> Build Settings -> Architectures, which looks like this.

So I have a new question: can I really simply remove armv7s and arm64 from Valid Architectures without any consequences? Will the app run on all the devices it should? In all the related discussions I've read through I couldn't find a definite answer to this.
