UXPlatform

UXPlatform hands an application the driver for the backend its build links. With it, main() has no platform-aware line:

#import "UXPlatform.xc"

void main(void) {
    UXApplication* app = new UXApplication();
    app.setDriver(UXPlatform.driver());
    app.setDelegate(new Controller());
    app.run();
}

Overview

The backend follows the target where the target decides it: win64 is Win32, wasm32 the web, arm9 GEM, ios-sim and ios iOS, android Android. Otherwise the build names it with -D UX_GTK or -D UX_GEM (GEM on a host). With neither, an arm64 build is the Mac’s AppKit and an x86_64 build is GTK on Linux. Only the driver the build uses is imported.

A build script may differ per platform, in its link flags, its shims and these defines. The .xc source does not.
