This is a concept re-implementation of the @Binding and @State property wrappers from SwiftUI | |
The only purpose of this code is to implement those wrappers myself | |
just to understand how they work internally and why they are needed, | |
⚠️ This is not supposed to be a reference implementation nor cover all | |
subtleties of the real Binding and State types. | |
The only purpose of this playground is to show how re-implementing | |
them myself has helped me understand the whole thing better |
