Flurry Ads integration issue when using CocoaPods

I am using CocoaPods to integrate Flurry Ads in my project as per the instructions on the Flurry Developer Documentation.

I have my Podfile as below:

platform :ios, '9.0'use_frameworks!target 'Foo' do    pod 'Flurry-iOS-SDK/FlurrySDK'    pod 'Flurry-iOS-SDK/FlurryAds'end

I am not using a Bridging Header since in CocoaPods 0.39 we can use use_frameworks! to avoid the bridging header. I have set the 'Build Active Architecture' to Yes for Debug and No for Release.

This is the error I get: _OBJC_CLASS_$_FlurryXXXXXX referenced from FooViewController, linker command failed with exit code 1
