As you could see, there was a delay with good reads for Apple developers. Let's recap most of the good articles for these weeks. This would be long list of reads for the following week, not a weekend.

Let's dive in.

Multiple clones of now popular Wordle game were submitted to App Store, including those with $30 yearly subscription. None of these apps are related to original web game.

After the social network backlash Apple removed all these game clones from App Store.

However, this is not the only scam app on App Store. Another report shows that Apple even promoted scam app with purchased reviews.

So, the problem persists. On the other hand, sometimes unfair and unethical apps are still removed from App Store.
