Hi All. I have some incorrect code that is causing a compiler crash. Can somebody comment on whether this is worth a bug report? I was unable to match anything in JIRA.
The code can be found here: https://github.com/pepperdog/PepperDogFetch/tree/CompilerCrash-1 With some guidance as to what’s wrong, I may be able to make an isolated test, but as it is, there are too many layers. Thanks! -Kenny —— cut here 8<——8<—— CompileSwift normal x86_64 /Users/kenny/Projects/PepperDogFetch/PepperDogFetch/RelationalLayer/ResultSet.swift cd /Users/kenny/Projects/PepperDogFetch/iOSProject
