XCode project build fail: x duplicate symbols for architecure x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Question

I have come across this issue frequently when manipulating the pod file of my xcode project.

Wether I am adding a few pods or just a single one, this error seems to persist. When searching I mostly found that I had to run

pod install

or

pod update "some pod"

Both of these suggestions did not fix the issue even though when reading the documentation for pod update, it seems to be the exact command necessary.

In order to fix this issue all you have to do is

cat podfile

Make sure that all your pods are within the file, then

pod deintegrate
pod install
