XCode Linking Errors. Unity 5.2.3f1 XCode 7.2

Hi,

Just starting out with Unity and tried publishing an empty scene (with just a single plane, camera and directional light) to iOS (minimum version 8.0).

Ended up with a bunch of Linking errors (201 errors) on XCode when trying to compile to the iPhone 6 simulator:

ld: warning: ignoring file /Users/kusumaw/Desktop/Projects/Unity5/TestiOSProject/Build/iOS/iPhone/Libraries/libiPhone-lib.a, missing required architecture x86_64 in file /Users/kusumaw/Desktop/Projects/Unity5/TestiOSProject/Build/iOS/iPhone/Libraries/libiPhone-lib.a (3 slices) Undefined symbols for architecture x86_64: "_UnityADBannerViewFailedToLoad", referenced from: -[UnityADBanner bannerView:didFailToReceiveAdWithError:] in iAD.o "_UnityADBannerViewWasClicked", referenced from: -[UnityADBanner bannerViewActionDidFinish:] in iAD.o "_UnityADBannerViewWasLoaded", referenced from: -[UnityADBanner bannerViewDidLoadAd:] in iAD.o "_UnityADInterstitialADWasLoaded", referenced from: -[UnityInterstitialAd interstitialAdDidLoad:] in iAD.o "_UnityBindFramebuffer", referenced from:

Help?
