Well this is certainly a real bummer, folks. Swapchat, the popular unofficial Snapchat app for Windows Phone, has been pulled due to a copyright complaint filed by Snapchat. While there's the potential good news of an official client on the way for Microsoft's platform, until that day comes consumers are going to be stuck with no third party alternative.
Unfortunately, we had to remove Swapchat from the Store after a Copyright Complaint from Snapchat. Sorry guys.— SRC Apps (@src_apps) July 13, 2013
If you still have Swapchat installed, it's reported that all is okay and you can continue using the service as normal. If you haven't, you're going to have to wait for an official Snapchat app to be released. We'll keep you all in the loop with what's happening in the realm of Snapchat, but if tweets published by the SRC Apps team are to be taken seriously, we won't have to wait long.
