AppCoda Weekly - Issue #189

By AppCoda Weekly • Issue #189 • View online

WWDC20 finished almost two months ago, but still we are all talking about the new frameworks, APIs, and improvements announced this year. Among all those there’s something that is going to have a strong impact to the way we work when implementing in-app purchases in our apps. That is the brand new capability of testing StoreKit locally in Xcode 12.

StoreKit Testing allows you to test in-app purchases locally without the need of connecting to the App Store servers. In this week’s tutorial, we will walk you through StoreKit, show you how to set up the test environment, and test in-app purchases in a local environment.

By the way, a quick reminder about the early access discount of our new Machine Learning book. The discount ends in 10 days!

As always, hope you enjoy all the great tutorials we collect for you this week.

Talk soon,

Simon
