 ## Project Structure & Module Organization
 - Workspace with crates: `dash`, `hashes`, `internals`, `dash-network`, `dash-spv`, `key-wallet`, `rpc-*`, utilities (`fuzz`, `test-utils`), and FFI crates (`*-ffi`).
 - Each crate keeps sources in `src/`; unit tests live alongside code with `#[cfg(test)]`. Integration tests use `tests/` (e.g., `rpc-integration-test`).
-- Mobile SDK lives in `swift-dash-core-sdk/`; FFI bindings are in `*-ffi`. Shared helpers in `internals/` and `test-utils/`.
+- FFI bindings are in `*-ffi`. Shared helpers in `internals/` and `test-utils/`.
 
 ## Build, Test, and Development Commands
 - MSRV: 1.89. Build all: `cargo build --workspace --all-features`
 - Test all: `cargo test --workspace --all-features` or `./contrib/test.sh` (set `DO_COV=true`, `DO_LINT=true`, `DO_FMT=true` as needed)
 - Targeted tests: `cargo test -p dash-spv --all-features`
 - Integration RPC: `cd dash-spv && DASH_SPV_IP=<node-ip> cargo test --test integration_real_node_test -- --nocapture`
-- FFI iOS builds: `cd key-wallet-ffi && ./build-ios.sh` or `cd swift-dash-core-sdk && ./build-ios.sh`
+- FFI iOS builds: `cd key-wallet-ffi && ./build-ios.sh`
 - Lint/format: `cargo clippy --workspace --all-targets -- -D warnings` and `cargo fmt --all`
 - Docs: `cargo doc --workspace` (add `--open` locally)
