I am having trouble with this issue after updating Firebase through CocoaPods.
Any help is greatly appreciated.
Any Firebase Version beyond 4.0.2 causes the same error in Xcode (version 10.1).
The error:
Swift Compiler Error
'string' file not found
could not build Objective-C module 'CoreFoundation'
Already tried:
clean project
add SDK manually
removing level db and adding manually
Where is the issue? With the Swift file/header? With leveldb? Or Firebase?
Related (similar issue on GitHub, but the suggested solutions there do not work for me):
