 #### iOS Build
 
+iOS builds require full Xcode with the iOS SDK installed and CocoaPods on your
+`PATH`. Select the intended Xcode installation with `xcode-select`.
+
+For a Release device archive, run `make ios`. It rebuilds the frontend and native
+projects, selects the generated workspace and matching scheme (`Devplace` for
+development, the configured brand name for production), and writes an unsigned
+`.xcarchive` and `.xcarchive.tar.gz` under `bin/`. Set
+`SP_PRODUCTION_RELEASE=true` for the production app. Signing/exporting the archive
+for distribution is a separate step; installing on a physical device requires
+your Apple development team and provisioning profile.
+
+Prebuild also raises pod deployment targets below React Native's minimum,
+including privacy/resource bundles rejected by Xcode 27. Higher pod minimums are
+preserved. Regenerate with `pnpm app prebuild` after changing native configuration;
+do not edit generated Xcode projects or the Podfile.
+
+For a simulator or development-device build:
+
 ```shell
 pnpm run app ios
 ```
