Because of this one reason, build always fails...Any ideas about what I could try?
EDIT: the solution is to open the xcworkspace instead of the xcproject!
I Had this Issue several Times with PODS Libraries.
Here is something you can Try:
Run pod cache clean --all
and pod install
again.
Check your Header Search Paths and Library Search Paths, Remove all entries and place $(PROJECT_DIR) in recursive mode and $(inherited) as a Second Entry
Go to your target Build Settings -> Other linker flags -> double click . Add $(inherited) to a new line.
