Update (4am PDT 12 April 2016): Some of the third-party Reddit clients have now returned to the App Store. Both Narwhal and Antenna are now available in the App Store, but both have been updated to remove the NSFW toggle that used to be in their apps. It is our understanding that Apple's objection is with the implementation of those NSFW toggles. Apple wants them removed from all Reddit apps so that if a user does want to view NSFW content, that toggle must be manually changed from the Reddit website.
Today, numerous third-party Reddit clients were removed from the App Store by Apple for breaching clause 18.2 of the App Review Guidelines. This clause states that apps will be rejected if they contain "user generated content that is frequently pornographic".
The official Reddit app, which launched last week and was featured by Apple on the App Store, currently remains in the App Store, but other Reddit clients including Narwhal, Antenna, Eggplant and BaconReader have all been removed for sale. These third-party Reddit clients were removed from Apple without any advance notice to developers, despite some of the apps being available on the App Store for well over a year. It should also be noted that many of these third-party apps, such as Narwhal, did have a filter to enable or disable NSFW content.
It is our understanding that Reddit did not ask Apple to remove the third-party Reddit apps. This aligns with Reddit's statement from last week (after the launch of the official Reddit app) in which Reddit's VP of Consumer Product stated "if you already have an app you like, you're free to continue enjoying it".
Rick Harrison, co-author of the Narwhal Reddit client provided this quote to MacStories:
It also seems that a few other popular third-party Reddit apps were removed from the store, but not the official Reddit app. I reached out to Reddit asking them if they knew anything, and they informed me that they did not request Apple to pull these apps, and they were also receiving issues from Apple about 18.2. I think that Apple did not pull their app because they are a big company and were recently featured. As shown time and time again, Apple does not really care whatsoever about indie developers. From taking 30% of barely any revenue to rejecting apps based on features that have been available for 18+ months.
It is too soon to say, but Apple's actions today may well be the latest example of policy and procedural failure on App Review. We covered this topic in detail in a story last month which chronicled the depth of developer frustration at App Review.
We will continue to monitor this story and provide further updates and details as we come across them.
