Hello,
I'm seeing a crash in production in my app. I'm wondering if I could get any help with this.
Issue: Crash when an array of objects is converted into a map via calls to .map() and .reduce(). Accessing a lazy var causes the map/reduce call, and results in this crash.
This code has been working for almost year, and started to fail in production since our update to Xcode 14.2.
OS versions vary from 15.7 to 16.4.x.
