Description

vapor_jwt is failing to build on and internal/6.1 with the following error

error: compile command failed due to signal 6 (use -v to see invocation)
<unknown>:0: note: automatic synthesis of 'Hashable' is not supported for class declarations
SIL verification failed: method does not appear in the class's vtable: VerifyClassMethodVisitor(member).Seen || operandType.isForeignReferenceType()

This is actually an issue with MemberImportVisibility. @tshortli is looking into this. @justice-adams-apple we have a radar for this - rdar://142433039
