Many years ago I put an attribute named throws in a core data entity. Now I want to extract the data and move it to a new swift data with more function. I try to rename the entity to avoid compile problems with throws being a swift keyword, now banned as a SwiftData field.

I need a code path to extract from the original core data using swift. The SwiftData macros seem to choke on the throws keyword and substitute blanks.

DB rename of the attribute still uses the original throws name at the code level.

If I understand you correctly the issue is that you can't use the word throws in your code as an attribute name but maybe you can work around that by using backticks around it.

I know this works fine for variables and properties and in custom types so hopefully it works within a Core Data/SwiftData context as well.

So something like this should work,

var `throws`: String

To evolve from an attribute named throws, you can follow these steps:

Identify Usage:

Determine where the throws attribute is used within your codebase. This includes checking for its definitions, method signatures, and any relevant documentation.

Rename the Attribute:

If you want to change the attribute name, consider a more descriptive name that conveys its purpose more clearly. Ensure the new name adheres to your project's naming conventions.

Update References:

After renaming the attribute, update all references throughout your codebase. This includes method calls, property accesses, and any related documentation or comments.

Testing:

Conduct thorough testing to ensure that the change has not introduced any issues. Check for both unit tests and integration tests that might be affected by the renaming.

Documentation:

Update any relevant documentation to reflect the new attribute name. This helps maintain clarity for future developers who will work with your code.

By following these steps, you can effectively evolve from the throws attribute while maintaining code clarity and functionality. If you have further questions or need more specific guidance, feel free to ask!
