IOS13 beta 5: Does SKProductsRequest supposed to work on simulator?

The issue has been fixed by Apple in Xcode beta 6 (August 16th, 2019).

[UPDATE Sept 30th 2019]

For those who's still experience the issue, did you download Xcode v11.1 (11A1027), Released on September 24, 2019? I don't have any issue with it. If you still, try to add some information so that I can help you further.

Had the same problem, as mentioned in the comments to the author's answer.

( request:didFailWithError: with error message being: Error Domain=ASDErrorDomain Code=507 "Error decoding object" UserInfo={NSLocalizedDescription=Error decoding object, NSLocalizedFailureReason=Attempted to decode store response} )

I changed project's iOS deployment target to iOS 13.0 and products loaded successfully in a simulator.
