Bug: The condition if association.ext.is_empty() is inverted. It prevents file extensions from being added to the macOS bundle's Info.plist when they are present.
_{Severity: CRITICAL}

Suggested Fix

Invert the condition to correctly add the extensions when the list is not empty. Change if association.ext.is_empty() to if !association.ext.is_empty().

Potential issue: The code checks `if association.ext.is_empty()` before adding
`CFBundleTypeExtensions` to the macOS application's `Info.plist`. This logic is
inverted. When `association.ext` contains extensions, the `if` block is skipped, and the
extensions are never registered. When `association.ext` is empty, an empty array is
added. This will cause file associations to fail on macOS for applications that define
them, as the operating system will not be aware of the file types the application can
handle.
