Looking at the KMMBridgeKickstart … Can someone explain why the analytics module is listed as an
api()
dependency (and is exported in the cocoapods configuration)?

I think that was to save needing to forward calls through the umbrella module. We went back and forth a bunch internally over how much detail we wanted to go into in that module structure.
analytics is a relatively simple API so exposing that isn't as heavy as exposing something like a bunch of database tables

So, it was “we chose to” and not, “we had to”, right?

Soo … here’s something I’ve noticed anecdotally … My
allShared
module has a dependency on another module called
adw-program
.
adw-program
defines a class, called
Program
.
allShared
defines a class called
IosContainer
.
IosContainer
has a function,
getProgram()
that returns an instance of
Program
. in my
allShared
module, if i use
implementation
for the
adw-program
dependency, and don’t export it via the cocoapods framework, then in my swift code, the
Program
class’s type is actually
Adw_programProgram
… Also, any of the other classes in my
adw-program
module are NOT available at all in my ios/swift project. the
Adw_programProgram
class is available only because the
IosContainer
has a method that returns an instance of it. However, if I make the
adw-program
an
api()
dependency (and export it via cocoapods), then things in Swift are more “what you would expect”. I have a
Program
class, and I can see all of the (public) classes declared in
adw-program
.

yeah, that's about what I would expect. If you export, you'll get everything without a prefix. If you don't export, you'll get only the minimal set of things that are exposed via the public API of your top-level module, and they will be prefixed
One option for more fine-grained control is to split
adw-program
into two separate modules. One has just the public API that you'll expose through
allShared
and the other has impls and internal details. Then you can export the API module but still control what gets exported based on whether it's in the api or the impl module, and you won't see the module name prefix on things from the api module.

04/19/2023, 9:00 PM
yeah, that’s kind of what I’m doing.
adw-program
exposes my “Repository”, and there are additional modules for
adw-network
,
adw-storage
, etc that have the ktor and sqldelight stuff. I also have
adw-models
that contains all of the models (data classes), so that one I definitely want to use api exports for.
So I’ll probably end up with
adw-program
and
adw-models
being exported api’s, and all the others being implementations that are kept “internal” to the library
