go: x/mobile: bind framework not found by Xcode

What version of Go are you using (`go version`)?

$ go version
go version go1.13.4 darwin/amd64

Does this issue reproduce with the latest release?

I believe I am on the latest version

What operating system and processor architecture are you using (`go env`)?

What did you do?

gomobile bind -o frameworks/ios/Shared.framework -target=ios

This completed successfully and I got a folder named Shared.Framework with obj-c files.

I drag and drop this into Xcode 11.2.1 (11B500) to use it in my app.

What did you expect to see?

I expected to be able to compile the app and use the framework in my Swift code.

What did you see instead?

The Xcode project no longer compiles, but fails with:

ld: framework not found Shared clang: error: linker command failed with exit code 1 (use -v to see invocation)

I alos tried adding the absolut path to Xcode build setting Framework search paths without success.

Thankful for your help!

Okey I got it working now! What was causing the issue was probably my use of the name “Shared” when there where no Go package called “shared” in the files I was binding.

If i omit the naming of the output -o and just bind it, the frameworks gets a different name but this frameworks gets found by Xcode and can be used, awesome!

But then a follow up question, is it not possible to name my framework to something custom?

In my case I am binding 3 different Go packages and want to create a single output framework of that. I do this like this:

gomobile bind -target=ios \ services/departure \ services/search \ presenters

And then the name of the framework becomes Departure, so I guess it just gets the name of the first package argument I give to bind.

So it works but it would be nice to name it something else. And am I doing it right when binding my 3 packages like I do?

Thanks.
