+## KC-7 — App Store upload: "iPad Multitasking must provide a launch screen"
+
+**Status:** Resolved (fix in `72f4566`; re-archive required to ship)
+**Reported by:** User (App Store / Transporter validation)
+**Area:** Build / App Store
+
+### Symptom
+Upload fails validation:
+> Invalid bundle. Apps that support Multitasking on iPad must provide the app's
+> launch screen using an Xcode storyboard, or using UILaunchScreen … Verify that
+> the UILaunchStoryboardName key is included in your com.kutesir.KisaniCal bundle.
+
+### Root cause
+The app targets iPad (`TARGETED_DEVICE_FAMILY = "1,2"`) with multitasking
+(`UIApplicationSupportsMultipleScenes = true`), but `project.yml` had
+`INFOPLIST_KEY_UILaunchStoryboardName: ""` (empty) and no `UILaunchScreen` —
+so the bundle shipped no valid launch screen.
+
+### Fix
+- Added `KisaniCal/LaunchScreen.storyboard` (blank, `systemBackgroundColor`).
+- `project.yml`: `INFOPLIST_KEY_UILaunchStoryboardName: LaunchScreen`.
+- `xcodegen generate`. Verified a clean **Release** build emits
+  `UILaunchStoryboardName = LaunchScreen` and ships `LaunchScreen.storyboardc`.
+
+### ⚡ If it happens again — solve it fast
+This error almost always recurs because a **stale archive** was uploaded, NOT
+because the code is wrong. Checklist:
+1. Confirm the fix is present:
+   `grep UILaunchStoryboardName project.yml` → must be `LaunchScreen` (not `""`).
+   `git log --oneline -- KisaniCal/LaunchScreen.storyboard` → should show `72f4566`.
+2. If Xcode was open, **reload the project** (xcodegen rewrites `.xcodeproj`).
+3. **Product → Clean Build Folder (⇧⌘K)** — a cached build folder re-emits the old
+   Info.plist. This is the step people skip.
+4. **Bump `CURRENT_PROJECT_VERSION`** in `project.yml` + `xcodegen generate`
+   (a failed upload can "use up" the build number).
+5. Re-Archive → Validate → Distribute.
+6. Sanity check any archive:
+   `/usr/libexec/PlistBuddy -c "Print :UILaunchStoryboardName" <App>.app/Info.plist`
+   and `ls <App>.app | grep LaunchScreen` (expect `LaunchScreen.storyboardc`).
+
+Committed: fix `72f4566`, build-number bump `345415e`.
