I got warning for the following method:
public NSArray<User> users() { return EOUtilities.objectsForEntityNamed(ec(), "User"); }
It said that "Type safety: The _expression_ of type NSArray needs unchecked conversion to conform to NSArray<User>"
How to provide 'unchecked conversion'?, What's the recommended way to fix this?
A suggestion has been provided, but here's an alternative. If you're using the standard WOLips/Wonder templates to generate your EO classes, you can re-write that as:
public NSArray<User> users() { return User.fetchAllUsers(ec()); }
That method is properly genericised, and so doesn't need casting or warning suppression.
