App Submission Issues

I bet many iOS developers are busy submitting apps to the App Store lately after fixing issues on iOS 9. This blog post just listed the issues I came across lately when submitting apps to App Store.

  1. I was using Xcode 7 GM to submit one app, which uses Carthage and Realm. Here is error message:

Unsupported architectures. The executable for xxxx/Realm.framework contains unsupported architectures [x86_64, i386]

Unsupported architectures. The executable for xxxx/RealmSwift.framework contains unsupported architectures [x86_64, i386]

The reason is that dynamic library has i386 or x86_64 code and we cannot embed them in the app, so we need to strip out any non-arm code from the app.

After some research I found the script from this blog, just go to the tab page "Build Phases" of the app target in Xcode, add a "New Run Script Phase", copy the script and paste there, archive your app then it should work. Here is the script:

APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"

# This script loops through the frameworks embedded in the application and
# removes unused architectures.
find "$APP_PATH" -name '*.framework' -type d | while read -r FRAMEWORK  
do  
    FRAMEWORK_EXECUTABLE_NAME=$(defaults read "$FRAMEWORK/Info.plist" CFBundleExecutable)
    FRAMEWORK_EXECUTABLE_PATH="$FRAMEWORK/$FRAMEWORK_EXECUTABLE_NAME"
    echo "Executable is $FRAMEWORK_EXECUTABLE_PATH"

    EXTRACTED_ARCHS=()

    for ARCH in $ARCHS
    do
        echo "Extracting $ARCH from $FRAMEWORK_EXECUTABLE_NAME"
        lipo -extract "$ARCH" "$FRAMEWORK_EXECUTABLE_PATH" -o "$FRAMEWORK_EXECUTABLE_PATH-$ARCH"
        EXTRACTED_ARCHS+=("$FRAMEWORK_EXECUTABLE_PATH-$ARCH")
    done

    echo "Merging extracted architectures: ${ARCHS}"
    lipo -o "$FRAMEWORK_EXECUTABLE_PATH-merged" -create "${EXTRACTED_ARCHS[@]}"
    rm "${EXTRACTED_ARCHS[@]}"

    echo "Replacing original executable with thinned version"
    rm "$FRAMEWORK_EXECUTABLE_PATH"
    mv "$FRAMEWORK_EXECUTABLE_PATH-merged" "$FRAMEWORK_EXECUTABLE_PATH"

done  

2.I was using Xcode 7 GM to submit one iPad app, which just supports landscape orientation, then encountered this error:

Invalid Bundle. iPad Multitasking support requires these orientations...

Invalid Bundle. iPad Multitasking support requires launch story board in bundle 'com.xxx....'

iPad Multitasking support requires all the orientations but the app does not, so we need to opt out it, just add the UIRequiresFullScreen key to your Xcode project’s Info.plist file and apply the Boolean value YES.

3.I was using Xcode 6.4 to submit one app, but got the following warning message after submitting the app to App Store.

Missing Push Notification Entitlement - Your app appears to include API used to register with the Apple Push Notification service, but the app signature's entitlements do not include the "aps-environment" entitlement. If your app uses the Apple Push Notification service, make sure your App ID is enabled for Push Notification in the Provisioning Portal, and resubmit after signing your app with a Distribution provisioning profile that includes the "aps-environment" entitlement.

Actually the app does not have any push notification code. Then I tried to resubmit the app using Xcode 7 and there is no warning anymore. It might be a bug that is also mentioned on StackOverflow.

4.I was using Xcode 7.3 to submit one app, then I got this error:

Command /usr/sbin/chown failed with exit code 1

This issue looks very weird, and I just fixed it by restarting Xcode.

Hope this helps,
Michael
