So without warning this week saw Apple unleash a new feature which is a good step forward for some apps but a potential disaster for others. Allowing old versions of apps to be downloaded is a great idea in theory but as Kyle Richter points out there are some significant downsides to it. Since launching this feature, Apple have updated it to allow specific old versions to be removed from sale but this doesn't solve the problems that we are now selling versions of an app which can't ever have bug fixes applied to them. It feels a little like this wasn't thought through before being implemented.
Note: In the article linked here it is not clear that the feature to remove specific versions from sale has actually been deployed by Apple and is live right now. We struggled to find the option to enable this but it does exist. Navigate into your app and then into to Rights and Pricing and then click Indicate a legal issue with iCloud for this app. Can I just be the first to say that this is a crazy place to hide this very important feature.
