I'm trying to move some older code for a reusable library to the Swift package format. The old code has an Objective-C class, used by Swift in the same library. Right now I get errors from Xcode 11 about how the "Use of undeclared type MyObjCClass". I've got the Obj-C code in one target, and the Swift code in a second target. Is there something to do so that the Swift code can see the Objective C class? Part of Package.swift:
targets: [
.target(name: "MyLib", dependencies: ["SomeCStuff"]), // swift
.target(name: "SomeCStuff") // C, Objective C
]
