Xcode Unit Testing with Cocoapods
I had the same issue. I solved it by moving pod 'Firebase' to my test target. Change your Podfile to this:
platform :ios, '9.0'use_frameworks!inhibit_all_warnings!target 'MyApp' do pod 'Firebase/Auth' pod 'Firebase/Database' pod 'Firebase/Storage' target 'MyAppTests' do inherit! :search_paths pod 'Firebase' endend
Try changing the inheritance to :complete, as in:
target 'MyAppTests' do inherit! :completeendImportantly it allows anyone else checking out your repo to just do a pod update as usual without having to copy .xcconfig files or other hackery just to build.
