Swift ObjectiveC Interoperability with App Target and multiple Static Libraries.

Let's discover

1. how to create a project where both swift and objective c belong to App Tarbet and interact with each other.

2. We will discuss more advanced by creating swift and objective c static library and how they can interact with each other.

3. We will discuss about module.modulemap and how it is helping us to modularise the APIs.

4. Let's create mix lanugage libraries where both swift and objective c code reside and use them.

Let's take an Example where the dependencies look like:

When Both Swift and Objective-C file resides at App Target:

When both swift and objc file reside in same static library:

swiftc (swift compiler) contains clang (objc compiler) as a module, we do not need any import objc_module_name in swift classes to use Objective c classes.

When Both Swift and Objective C reside in different Static Library:
