//! Build script that invokes swift-bridge's parser on our bridge
|
|
//! module and emits the corresponding Swift and C glue.
|
|
//!
|
|
//! The generated artifacts land in `OUT_DIR/swift-bridge`:
|
|
//!
|
|
//! - `OpenPay.swift` — the idiomatic Swift surface
|
|
//! - `openpay-swift-bridge.h` — the C header that Swift imports
|
|
//! - `module.modulemap` — declares the C header as a Clang module
|
|
//! that Swift's importer can find
|
|
//!
|
|
//! The downstream Xcode build copies these into the consuming Swift
|
|
//! package. See `scripts/build-xcframework.sh` for the full workflow.
