+# XcodeGen spec — generates ScanReceipts.xcodeproj on macOS.
+#
+# Why XcodeGen instead of a hand-committed .xcodeproj: the project file is a
+# fragile, Xcode-internal plist format tied to UUIDs Xcode itself assigns.
+# Generating it from this YAML on the machine that actually builds keeps the
+# real project file out of git entirely (see .gitignore) and avoids merge
+# conflicts in a format nobody can diff sensibly.
+#
+# Setup (macOS, once): `brew install xcodegen`
+# Generate the project:  `cd app/ios && xcodegen generate`
+# Then open ScanReceipts.xcodeproj in Xcode.
