# tele-ios-ffi

UniFFI bridge for the future native iOS app.

Current scope:

- Exposes a fake-backed `SessionHandle` for Swift integration tests and app shell work.
- Mirrors the `tele-core::session` DTO/event model with UniFFI-compatible records and enums.
- Supports a fake-only build for UI work and a real TDLib build path using local iOS TDLib artifacts.

Generate Swift bindings and headers:

```bash
scripts/generate-ios-ffi-bindings.sh
```

The script builds `target/release/libtele_ios_ffi.a` and writes Swift sources,
headers, a Swift typecheck-friendly `tele_ios_ffiFFI` module map, and an
XCFramework-compatible module map under `build/ios-ffi/`.

Build the fake-only iOS simulator XCFramework without linking TDLib:

```bash
DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/build-ios-fake-ffi-xcframework.sh
```

Run an executable Swift smoke test against matching fake-only UniFFI bindings:

```bash
DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/smoke-ios-ffi-swift.sh
```

Typecheck the Swift app bridge against generated UniFFI bindings:

```bash
DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer scripts/typecheck-ios-uniffi-app-bridge.sh
```

Current linking status:

- Xcode is installed at `/Applications/Xcode.app`, and `DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer xcodebuild -version` reports Xcode 26.5.
- The iOS 26.5 simulator runtime is installed and `scripts/check-ios-prereqs.sh` passes with available iPhone/iPad simulators.
- The current app shell uses the fake Swift bridge.
- `tdlib-rs` does not publish iOS `download-tdlib` archives, so real iOS linking uses `tele-core/tdlib-local` and `LOCAL_TDLIB_PATH`.
- Local TDLib linking is validated for `aarch64-apple-ios-sim` via `scripts/check-ios-tdlib-linking.sh` and for `aarch64-apple-ios` via `IOS_RUST_TARGET=aarch64-apple-ios scripts/build-ios-ffi-with-local-tdlib.sh`.
- `scripts/build-ios-real-ffi-xcframework.sh` packages local simulator Rust slices plus local `libtdjson` into app-local XCFrameworks, generates Swift bindings, and enables Xcode builds with `TELE_IOS_USE_LOCAL_FFI=1`.
