Using PropertyAccessor in your project

To use the PropertyAccessor library in a SwiftPM project, add the following line to the dependencies in your Package.swift file:

.package(url: "https://github.com/jrsaruo/PropertyAccessor", from: "1.0.0"),

and add PropertyAccessor as a dependency for your target:

.target(name: "<target>", dependencies: [
    .product(name: "PropertyAccessor", package: "PropertyAccessor"),
    // other dependencies
]),

Finally, add import PropertyAccessor in your source code.

Note

You may see an alert that says “'PropertyAccessorMacros' must be enabled before it can be used. Enable it now?” so you will have to trust and enable it.
