Swift 3 generic object wrapper gives EXC_BAD_ACCESS

wrapper.swift

/*

I've been using an object like ObjectWrapper in Swift 2.x without any problems
to store a Swift struct as a property an Objective-C object, and then later
access and use that struct from other Swift code.

Upon upgrading to Swift 3, trying to access the value field of the ObjectWrapper
results in an EXC_BAD_ACCESS. If I de-generecise things, ala PersonWrapper, then
everything works OK. Is this a Swift 3 bug, or something I shouldn't have been able
to do in the first place?

class ObjectWrapper<T> : NSObject {
	let value: T?
	
	init(value: T?) {
		self.value = value
	}
}

class PersonWrapper : NSObject {
	let value: Person?
	
	init(value: Person?) {
		self.value = value
	}
}

struct Person {
	let name: String
	let age: Int
	let country: String
}

let person = Person(name: "Brian", age: 38, country: "USA")
let testWrapper = PersonWrapper(value: person)

var newName: String
if let wrappedPerson = testWrapper.value { //This access works fine
	newName = wrappedPerson.name
} else {
	newName = "No person"
}
print(newName)

let testWrapper2 = ObjectWrapper(value: person)

if let wrappedPerson = testWrapper2.value { //This gives EXC_BAD_ACCESS
	newName = wrappedPerson.name
} else {
	newName = "No person"
}
print(newName)
