Flurry iOS Native Ad view composition

FlurryiOSNativeAdViewComposition.swift

func adNativeDidFetchAd(nativeAd: FlurryAdNative!) {
   NSLog("Native Ad for Space \(nativeAd.space) Received Ad with \(nativeAd.assetList.count) assets");
      for asset in nativeAd.assetList {
         switch(asset.name) {
            case "headline":
                streamTitleLabel.text = asset.value;
            
            case "summary":
                streamDescriptionLabel.text = asset.value;
            
            case "secImage":
                if let url = NSURL(string: asset.value!!) {
                    if let imageData = NSData(contentsOfURL: url) {
                        streamImageView.image = UIImage(data: imageData);
                    }
            }
            
            case "source":
                streamSourceLabel.text = asset.value;
            
            case "secHqBrandingLogo":
                if let url = NSURL(string: asset.value!!) {
                    if let imageData = NSData(contentsOfURL: url) {
                        streamSponsoredImageView.image = UIImage(data: imageData);
                    }
            }
            
            default: ();
      }
   }
}

It's hard to tell from the existing Pod documentation if nativeAd.space and nativeAd.assetList are guaranteed to be non-nil. You may want to add a guard before using them.

Use the native for-in syntax and switch statements to make this more concise and swifty. You can also lose some of the extra steps of creating optional NSURL and NSData instances.

e.g. (This was freehand, not guaranteed it compiles)

for asset in nativeAd.assetList {

    switch (asset.name) {
        case "headline":
            streamTitleLabel.text = asset.value

        case "summary":
            streamDescriptionLabel.text = asset.value;

        case "secImage":
            if let url = NSURL(string: asset.value) {
                if let imageData = NSData(contentsOfURL: url) {
                    streamImageView.image = UIImage(data: imageData);
                }
            }

        case "source":
            streamSourceLabel.text = asset.value;

        case "secHqBrandingLogo":
            if let url = NSURL(string: asset.value) {
                if let imageData = NSData(contentsOfURL: url) {
                    streamSponsoredImageView.image = UIImage(data: imageData);
                }
            }
    }
}

nativeAd.space and nativeAd.assetList will are guaranteed to be non-nil, as this method is a callback function which is called on successfully fetching an ad.

As for using the native for-in syntax, I'll update the gist with your respective changes.
