Classification:Serious bug Reproducible:Always
 
Summary:
When generating a Swift NSManagedObject subclass with Integer, Double, or Float properties, Xcode generates properties of NSNumber.

Steps to Reproduce:
1. Create an entity in Core Data with Integer, Float, Double attributes
2. Generate NSManagedObject subclass
3. Note that all properties are NSNumber instances

Expected Results:
For an entity with a Int64, Float, and Double, Xcode should generate the following Swift class:

class TestEntity: NSManagedObject {

    @NSManaged var myInt: Int64
    @NSManaged var myDouble: Double
    @NSManaged var myFloat: Float

}

Actual Results:
Xcode generates the following instead:

class TestEntity: NSManagedObject {

    @NSManaged var myInt: NSNumber
    @NSManaged var myDouble: NSNumber
    @NSManaged var myFloat: NSNumber

}
