I'm having the same problem… Here's what I found:

this issue would be due to Apple introducing a new typealias called SubscriptionPeriod in iOS 18.4, which I guess clashes with an existing class in RevenueCat, because namespacing in Swift is fun.
https://developer.apple.com/documentation/storekit/subscriptionperiod
So if the code is in RevenueCat, they will need to prefix it with RevenueCat eg RevenueCat.SubscriptionPeriod.
