Issue Description​

iOS 18.0 introduced a bug which sometimes causes purchases to fail on-device, impacting the RevenueCat SDK's ability to display the purchase sheet to end users. When this bug occurs, no money is moved and the RevenueCat SDK's purchase functions throw a STORE_PROBLEM error.

Symptoms​

  • Calling any of RevenueCat's purchase functions to make a purchase on iOS 18.0-18.3.2 may fail.
  • StoreKit will log an error message in the following format to the console. The NSCocoaErrorDomain Code will always be 4097.
Product purchase for '${PRODUCT_ID}' failed with error:
systemError(Error Domain=NSCocoaErrorDomain Code=4097
"connection to service with pid ${PID} named com.apple.storekitd"

Workarounds​

Status​
