HelloWorldMacro

Super Simple Swift Macro

SUMMARY

To understand the structure of Swift Macros, I created a simple macro as a basic functionality.
This macro appends Hello World to any input string.

USAGE

let value = #sayHelloWorld(with: "XXXX") // "Hello World XXXX!!!"

HOW TO TESTING FOR MACROS

1	Switch the scheme to MacroFeature
2	Select My Mac from the Macs as the device to run on
3	If set up this way, it is possible to test

PRECONDITION

This time, the design involves adding macros within the app.
The project is separated into packages using the Swift Package Manager.
