Ugh. With 4.19.0 I get:
UATHelper: Packaging (iOS): ERROR: System.IO.DirectoryNotFoundException: Directory ‘/Users/Shared/Unreal Projects Local/icontest418release 4.19/Build/IOS/Build/IOS/Resources/Graphics’ not found.
UATHelper: Packaging (iOS): RunUAT ERROR: AutomationTool was unable to run successfully.
PackagingResults: Error: Unknown Error
I will try to make a new project and test. This was just a test project to see what is in the .ipa
