This happened to me when I set up a development target. The production target was working fine but the development kept bringing up those errors. My issue was in the pod file. At first:

target 'NAME-OF-TARGET' do
# Comment the next line if you're not using Swift and don't want to use dynamic frameworks
use_frameworks!

# Pods for MAIN-TARGET
pod 'GoogleSignIn'
pod 'Firebase/Core'
pod 'Firebase/Database'

target 'DEV TARGET' do
    inherit! :search_paths           <----------
    # Pods for dev-target
    pod 'GoogleSignIn'
    pod 'Firebase/Core'
    pod 'Firebase/Database'
end

The line I have indicated the arrow was the issue. I changed it from inherit! :search_paths to use_frameworks! and the errors were done.
