App Store receipt signing certificate changes in 2023

Apple announced a change in the App Store receipt signing certificate, requiring developers to update their apps by February 7th to avoid validation failures due to the expiration of the old certificate. This change primarily affects apps using on-device receipt validation with hardcoded certificates, which could lead to paying users losing access to content if the update isn't made. Apple recommends updating the validation process to match their guidelines, which involves passing receipt data through a secure server, although this can be complex and time-consuming. Alternatively, developers can switch to solutions like RevenueCat, which offers an easier implementation and additional features for managing app subscriptions. The situation highlights the ongoing challenges developers face in keeping up with evolving technical requirements of the App Store, emphasizing the importance of using reliable tools to focus on core app development.
