Issues with app delivery!

[Rick Harrison]

I had a couple of issues with the delivery of my
to the apple app store.

I followed Kee’s livecode lesson exactly, so what
do I need to do to fix this?

Here are the issues:
i386 (in com.(..myappname..).app/Contents/MacOS/revsecurity.dylib)
App sandbox not enabled - The following executables must include the "com.apple.security.app-sandbox" entitlement with a Boolean value of true in the entitlements property list. Refer to the App Sandbox <https://developer.apple.com/devcenter/mac/app-sandbox/> page for more information on sandboxing your app.
Your help is appreciated in advance!
Thanks,
Rick
