Same class of fix as the Android NDK build: rquickjs-sys has no prebuilt
FFI bindings for Apple targets, so bindgen needs the iOS SDK sysroot and
clang target triple explicitly, or it falls back to the host's own
headers and fails. Unverified — this machine has no Xcode/macOS to
actually run the build; needs confirming on a real Mac.
Phase 0 of the fluxa-android KMP/CMP migration needs an xcframework +
Swift UniFFI bindings for fluxa_core. Adds an "ios" feature (full-api +
uniffi-bindings, no jni/dolby_vision, mirroring the existing "desktop"
feature), a staticlib crate-type for xcframework embedding, a
[bindings.swift] uniffi.toml section, and a macOS-only build script
that produces FluxaCore.xcframework for aarch64-apple-ios and
aarch64-apple-ios-sim.
Verified on Linux: `cargo check --target aarch64-apple-ios --features
ios` and the aarch64-apple-ios-sim equivalent both compile cleanly, so
the crate itself has no Android/JNI-only code leaking into the iOS
feature set. Actual linking/xcframework packaging needs a Mac with
Xcode — untested here.
