# Logseq iOS Simulator Build & Launch ## Prerequisites - macOS arm64 with Xcode installed (`xcodebuild -version` works). - opam switch `5.5.0` with dune (`opam exec --switch=5.5.0 -- dune --version`). - An iOS simulator: `xcrun simctl list devices available | grep iPhone`; boot one with `xcrun simctl boot <UDID>`. ## Build steps 1. `scripts/bootstrap-ios-ocaml.sh simulator` — builds host + cross OCaml 5.5.0 under `_build/apple-toolchains/ios/` (long first run; stamps skip rebuilds). 2. `scripts/build-mobile-ios-simulator.sh` — builds `shared/native/logseq_mobile_entry.exe.o` via dune context `ios_simulator`, then `swift build` (product `LogseqShell`), xcodebuild for the share/widget extensions, and assembles+codesigns `.build/Logseq.app`. Note: the script can exit non-zero at the end even when all artifacts are produced correctly — re-running it (incremental) and checking for `.build/Logseq.app/Logseq` is the practical check. 3. `xcrun simctl install booted .build/Logseq.app` 4. `xcrun simctl launch booted com.logseq.logseq` → prints `com.logseq.logseq: <pid>`; verify the process stays alive via `xcrun simctl spawn booted launchctl list | grep logseq`. 5. Screenshot: `xcrun simctl io booted screenshot out.png`. ## Pitfalls - `bootstrap-ios-ocaml.sh` host `./configure` must pass `--without-zstd`, else zstd-compressed .cmi files break the LG toolchain later (LG2000 errors). - Cross-compiling OCaml for iOS: configure's link-only `AC_CHECK_FUNC` detects symbols (pipe2, dup3, accept4, execvpe, prctl, secure_getenv, __secure_getenv) that link but are NOT declared in the iOS SDK headers → "call to undeclared function" errors under modern clang. Fix by passing `ac_cv_func_<name>=no` to the target configure. Check for more with a compile probe: `xcrun --sdk iphonesimulator clang -target arm64-apple-ios17.0-simulator -isysroot <sdk> -c t.c` where t.c calls the function after including the SDK headers. - First launch may show a local-network permission alert; dismiss it via Simulator UI. - The app opens to a "Logseq / Sign in" screen (Cognito hosted UI); going past it requires credentials. - `duniverse/` pulls only the lockfile dirs (129). The `logseq/*` pins NOT vendored (`datascript-ocaml`, `lg`, `lui`, `mldoc`, `persistent-sorted-set-ocaml`, `signal-lg`) must be cloned manually into `duniverse/` at the SHAs listed in `logseq.opam` — same loop as `.github/workflows/e2e.yml`. A fresh `opam-monorepo pull` wipes these dirs, so re-clone them after each pull. - `scripts/build-mobile-ocaml.sh` regenerates `_build/dune-workspace.mobile` from `dune-workspace.mobile`; set `LOGSEQ_OPAM_SWITCH=5.5.0` when running outside `opam exec`. ## Maestro e2e (test-ios-e2e-suite.sh) - Install Maestro: `curl -fsSL https://get.maestro.mobile.dev | bash` → `~/.maestro/bin`. - The e2e flows hit the app's sync server at `http://127.0.0.1:8787`. That server is `deps/db-sync` in the `logseq` repo, and it MUST run from the `feature/native-mobile-app` branch (the canonical `../logseq-1` checkout) — the app requires `schema-version` in the `/sync/<id>/snapshot/download` response, which only exists there (`main` returns without it → "Add sync graph" fails with `NSURLErrorDomain Code=-1017`). Setup: `cd ../logseq-1/deps/db-sync && pnpm install && clojure -M:cljs release db-sync-node` (needs `JAVA_HOME=$(/usr/libexec/java_home -v 21)`), then `DB_SYNC_PORT=8787 DB_SYNC_DATA_DIR=~/db-sync-data ./start.sh`; health check `curl http://127.0.0.1:8787/health`. - Run: `LOGSEQ_IOS_SKIP_BUILD=1 LOGSEQ_E2E_USERNAME=<u> LOGSEQ_E2E_PASSWORD=<p> ./scripts/test-ios-e2e-suite.sh smoke` (4 flows: capture-responsive, cold-start-composer, search-status-regression, sidebar). - `scripts/test-ios-e2e.sh` wipes the app data container between flows; `<container>/tmp` must be recreated (the script does `mkdir -p`) or the OCaml core crashes writing the initial graph snapshot via `Filename.temp_file` (`Sys_error ...tmp/logseq-initial-*.snapshot`). ## Devin Secrets Needed - `LOGSEQ_TEST_USERNAME` / `LOGSEQ_TEST_PASSWORD` for hosted sign-in and e2e.
