What did you do?

checked out the go mobile repo (follow instructions https://github.com/golang/go/wiki/Mobile) and opened it in xcode 11 and built.
verified Hello.framework exists in "Framework, Libraries and Embeded contents" and also listed in "Link Binary with Libraries".

What did you expect to see?

able to build and run the package.

What did you see instead?

"Module 'Hello' not found" in ViewController.m

I believe I experience the same issue. No matter what i bind, the framework is "not found" by Xcode. Even though there is an actual framework produced as output by gomobile bind.

Had the same issue, if you don't copy the framework into your projects directory, you should add the main directory to the framework search paths of the target. I've added an explanation to https://github.com/golang/go/wiki/Mobile as well.
