Parse for iOS - Undefined symbols for architecture i386 - iPhone 4s, iPhone 5

Question

I am getting few similar Undefined symbols for architecture i386: ... "_OBJC_CLASS_$_PFAnalytics", referenced from: errors while building for iPhone 4s simulator or iPhone 5 simulator.

With iPhone 5s-> everything works great. What am I doing wrong?

I have Parse and Facebook SDK's installed via CocoaPods:

    target 'My app' do
    platform :ios, '8.0'
    pod 'Parse'
    pod 'FBSDKCoreKit'
    end

Update 1:

I have architectures selected like this:

    //Debug, Release
    ARCHS = $(ARCHS_STANDARD)

    //Debug, Release
    VALID_ARCHS = arm64 armv7 armv7s

Answer 1

I finally got it working with the help of CocoaPods community. Problem was with the DerivedData. I cleaned DerivedData for my project (in XCode 7, Window -> Projects) and it started working perfectly again.
