Missing Icon file / Missing Push / Non-Pie Binary Release questions

Hello I just uploaded my first Unity app and received this email,
Are these highlighted items reasons for a rejected review or can I ignore them?

I quote:-
Dear developer,
We have discovered one or more issues with your recent delivery for “APPS WORLD”. Your delivery was successful, but you may wish to correct the following issues in your next delivery:
Missing recommended icon file - The bundle does not contain an app icon for iPhone / iPod Touch of exactly ‘120x120’ pixels, in .png format.
Missing recommended icon file - The bundle does not contain an app icon for iPad of exactly ‘76x76’ pixels, in .png format.
Missing recommended icon file - The bundle does not contain an app icon for iPad of exactly ‘152x152’ pixels, in .png format.
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. See “Provisioning and Development” in the Local and Push Notification Programming Guide for more information. If your app does not use the Apple Push Notification service, no action is required. You may remove the API from future submissions to stop this warning. If you use a third-party framework, you may need to contact the developer for information on removing the API.
Non-PIE Binary - The executable ‘WORLD.app’ is not a Position Independent Executable. Please ensure that your build settings are configured to create PIE executables. For more information, refer to Technical Q&A QA1788 - Building a Position Independent Executable
If you would like to update your binary for this app, you can reject this binary from the Binary Details page in iTunes Connect. Note that rejecting your binary will remove your app from the review queue and the review process will start over from the beginning when you resubmit your binary.

many Thanks Unity folk for any comments.

I saw the last 2 as well, and it sounds like it’s just making sure you are aware, not that it will harm anything. The icons missing might make them reject though?

Thanks for the reply, on your suggestion have found this link.

near the end it suggests that using Xcode 5 is the simplest way ahead as these are the new icon sizes required that are catered for in that version.

Did you ever figure out the “Non-Pie Binary Release” problem? I am dealing with the same thing. I saw this tech doc on it, but can’t seem to find the settings in xcode to change.
