iOS - "could not generate package manifest"

[tsimmons]

Using: LiveCode 7.0.1 (latest stable release), OS X Mavericks (10.9.5), Xcode 6.1.1, iOS SDK 8.1
Building for iOS
Already have: all the icons and splash screen images, signing / provisioning certificate
Problem: This is my first project for the iOS - it will be a free app offered through the state agency I work for, and it will basically help employers understand how to comply with various employment laws. My project can build sufficiently to test in the iOS Simulator, but when I try to build the standalone, I get the following series of messages: "Building executable, Signing app bundle, Codesign wants to sign using key "WilliamSimmons" in your keychain" (to which I indicate "Allow"), Building classes, Assembling assets, There was an error while saving the standalone executable could not generate package manifest". I did not find any other posts with this specific error message listed for iOS builds. Any insight would be appreciated. Thanks!
