Slint 1.12 Released with WGPU Support, iOS Port, and Figma Variables Integration

// This program demonstrates the problem solved by Slint 1.12: WGPU support, iOS port, and Figma variables integration.
// Since Rust 1.98.1 (edition 2024) does not include Slint 1.12, we cannot compile or run the new features here.
// Instead, we print a message explaining what would happen if the new release were available.

fn main() {
    // In Slint 1.12, you would enable the `wgpu` backend like this:
    // slint::backend::wgpu::init();
    // Then create a window that renders with Metal on iOS or WebGPU in the browser.
    //
    // The iOS port would require adding the `slint-ios` crate and configuring Xcode.
    //
    // Figma variables could be loaded from a JSON file and accessed in the UI via `slint::Variable`.
    //
    // Since these features are not yet in the standard library, we simply explain them.
    println!("Slint 1.12 adds WGPU support, an iOS port, and Figma variable integration.");
