Permission Set Assignment using apex

Question

Is there a limitation with PermsissionSetAssignment object in Apex. can't we insert the records using apex?

I am unable to compile the class as it is saying "Variable does not exist: AssigneeId" and "Variable does not exist: PermissionSetId"

public static void insertperms(){
        PermissionSetAssignment ps = new PermissionSetAssignment();
                ps.AssigneeId = UserInfo.getUserId();
                ps.PermissionSetId = 'qweqweqwe'; 
               // permList.add(ps);
    }

Sounds like a probable naming collision. If someone created a class named PermissionSetAssignment in your org, you would get exactly this error. To work around it, you can use the more verbose Schema.SomeStandardOjbect notation.

Schema.PermissionSetAssignment assignment = new Schema.PermissionSetAssignment();

It's not a great idea to introduce this type of naming collision. If it's not too late to change course, I suggest doing so.
