Property `expirationDate` of `NSUserActivity` class is bridged as non-optional `Date` in Swift 3.0 (Xcode 8.2). Reading the property makes the app crash.

From NSUserActivity header:

    /* If non-nil, then an absolute date after which this activity is no longer eligible to be indexed or handed off. */
    @available(iOS 9.0, *)
    open var expirationDate: Date


Steps to reproduce:
1. Create an NSUserActivity object
2. print(userActivity.expirationDate)

Expected results:
Prints out the value of expirationDate property

Actual results:
Crash - EXC_BAD_INSTRUCTION (code=EXC_i#*^_INVOP, subcode=0x0)

Fixed in iOS 11 / Xcode 9 beta 4

From the header:

/ If non-nil, then an absolute date after which this activity is no longer eligible to be indexed or handed off. / 

@available(iOS 9.0, *)
open var expirationDate: Date?
