I try to implement the Native Ad on Xcode8. I met crash issue. "NativeAdSample(10831,0x1b6871c40) malloc: *** error for object 0x1740b1100: pointer being freed was not allocated".
Even, I use the "NativeAdSample" example project from Official Facebook iOS SDK. And I get the same issue. After I assign the "PlacementID" and "addTestDevice", and I click the "Load Native Ad" button. And then it crash.
