Not to long ago Frederico Viticci of Macstories wrote this post. In it highlighting why these prerelease app reviews were harmful to developers. Seeing as betas like iOS 9 are still not out for the public its understandable that there’ll be bugs with certain 3rd party apps. As developers work to update for the upcoming version.
As Frederico states
Betas are, by definition, unfinished software, and unfinished software has bugs and works inconsistently. As Apple writes on their Beta Software Program website, “you can take part in shaping Apple software by test-driving pre-release versions and letting us know what you think”.
Developers here are crippled in that they literally can’t post updates for iOS 9 & OS X El Capitan as the App-Store won’t allow it. So users on these betas have who’ve been experiencing bugs have been taken to the review section.
However as of today that changes as Apple now restricts anyone from writing reviews on prerelease versions of iOS, as it should be. While most apps work fine on iOS 9 there are still some bugs & crashes you’ll experience that aren’t on the fault of developers who are well aware of the issue. As of right now this is limited to iOS but we’ll surely see this adapted to OS X betas as well. For now however it’s a good start.
