I use SwiftyStoreKit to request In App Purchases and get only this error with iOS 13:
Error: Optional(Error Domain=ASDErrorDomain Code=507 "Error decoding object" UserInfo={NSLocalizedDescription=Error decoding object, NSLocalizedFailureReason=Attempted to decode store response})
I cannot request information about the products, nor make purchases with a sand box account. However, it works fine in iOS 12.1 on my device. It does not work with the iPhone 11 simulator or an actual device with iOS 13.
I have found a lot, that the Xcode 11 GM seed 1 beta simulator had this problem, but have not found a solution yet. I also tested it with the new released Xcode 11 GM seed 2 version, but there was no fix for me.
Does anyone have a solution on how I can request and purchase In App Purchases again with iOS 13 installed?
Best Answer
Restarting Xcode and simulator did the trick: now my in-app purchases load properly in iOS 13 simulator.
EDIT: This happens in release Xcode 11 too. And happens once in a while, but restarting Xcode and simulators still helps.
EDIT 2: In Xcode 12 beta this bug is also present. But the solution is to create new StoreKit Configuration file (in
File -> Newmenu)Then add all your products there. Use the same product id's as in AppStore Connect.
Then add this file to Run Scheme configuration.
