'Class' is ambiguous for type lookup in this context

Question

I did a core-data model:

class Order: NSManagedObject {
    ... //code
}

but when I try to build I get an error:

'Order' is ambiguous for type lookup in this context

Answer 1

so I figured - the Entity 'Order' should be defined in the core data properties panel.

1. open core data .xcdatamodeld file

2. select the Entity 'Order'

3. On the right select "Current Product Module" under module

4. select "Category/Extension" under Codegen

Answer 2

Below are steps that worked for me,

• Delete "NSManagedObject" files created
• Clean build
• Open core data .xcdatamodeld file
• Open the right pane by selecting "Entity"
• Set Module to "Current Project", Codegen to "Module None" Setting One Ref Image
• Now go to Editor Menu from the top and create a subclass "NSManagedObject"
• Build the project
• Go back to Enity right pane and change Codegen to "Class Definition" Setting Two Ref Image

I feel the right solution is to delete the files created by Xcode foe the entity class and attribute class and change the codegen to class definition.

I had the same issue, on codegen option i had choosen class defination,To fix this: 1.Delete the generated class files 2. Select the Order Entity and on codegen on your right hand side choose manual\none 3. Navigate to Xcode Editor and select "Create NSManagedObject subclass to generate the classes again.

Answer 6

In my case I had an entity named "Client". Client seems to be used internally under the hood somewhere. Changing the entity name to "Company" resolved the issue. So check if your naming is reserverd by the system or other components.
Be sure to change both entity and class name (at least the class name).

2. Click on one of your entities

3. Press this button on the top-right of the screen

4. Select the last tab and fill in this information
