+# iOS Release Checklist
+
+## Support Matrix
+
+- Minimum iOS: 17.0
+- Swift package shell also builds on macOS 14 for local smoke coverage.
+- Rust targets: iOS device and simulator targets still need TDLib validation.
+- TDLib: `tdlib-rs` 1.2.0 with `download-tdlib`; iOS packaging is not validated yet.
+- Bridge: UniFFI 0.31.1 generated Swift bindings.
+
+## Required Before TestFlight
+
+1. Install and select full Xcode with `xcode-select`.
+2. Create the Xcode app project or wire the Swift package into an Xcode app target.
+3. Add app icon, launch screen, bundle id, signing team, notification capability, and entitlements.
+4. Build TDLib for simulator and device architectures.
+5. Package Rust static libraries and generated UniFFI Swift/header/modulemap output into an XCFramework.
+6. Run simulator smoke with fake bridge.
+7. Run real-device smoke with real Telegram credentials.
+8. Archive and upload to TestFlight.
+
+## CI Gates
+
+- `cargo fmt -- --check`
+- `cargo check -p tele-core`
+- `cargo clippy --workspace --all-targets --all-features -- -D warnings`
+- `cargo test --workspace --all-features`
+- `scripts/generate-ios-ffi-bindings.sh`
+- `swiftc -typecheck` for generated Swift bindings
+- `swift build --product TeleTuiIOSApp`
+- `swift run TeleTuiIOSSmokeTests`
+
+## Rollback
+
+1. Disable the TestFlight build in App Store Connect.
+2. Re-upload the previous known-good archive.
+3. If the issue is TDLib/session related, revoke the affected build and keep existing accounts on the previous app version.
+4. Preserve account Application Support directories; do not delete TDLib databases during rollback unless the issue is confirmed to be corrupted local state.
