App Submission Errors

[Dan Friedman]

Using LC 8.1.9, Max OS 10.12.6, XCode 9.2 I created my app for iOS.  I followed the instructions to create a ipa file.  When I upload the ipa with version 3.7 of Application Loader, I get these errors:

ERROR ITMS-90032: "Invalid Image Path - No image found at the path referenced under key 'CFBundleIcons': 'AppIcon60x60'"
ERROR ITMS-90023: "Missing required icon file. The bundle does not contain an app icon for iPad of exactly '76x76' pixels, in .png format for iOS versions >= 7.0."
ERROR ITMS-90023: "Missing required icon file. The bundle does not contain an app icon for iPad of exactly '152x152' pixels, in .png format for iOS versions >= 7.0."
ERROR ITMS-90022: "Missing required icon file. The bundle does not contain an app icon for iPhone / iPod Touch of exactly '120x120' pixels, in .png format for iOS versions >= 7.0."

Have I got a setting wrong?  Or is there a LC bug?

Anyone have any insight to share?
