Summary:

Exporting an app with Xcode 9 beta 3 (9M174d) results in a broken binary, when linking with the AddressBook framework and using NSDistributedNotificationCenter.

The application crashes at launch with the following error:

    Dyld Error Message:
    Symbol not found: _OBJC_CLASS_$_NSDistributedNotificationCenter
    Referenced from: /Users/USER/Desktop/AB.app/Contents/MacOS/AB
    Expected in: /System/Library/Frameworks/AddressBook.framework/Versions/A/AddressBook

Note that the crash does not occur when running the app on macOS High Sierra beta.
It only affects previous macOS versions (tested on 10.12 and 10.11).

Beta 3 of Xcode is the only version affected. Exporting the same app with the previous beta (9M137d) results in a working binary.

Attached is an Xcode project demonstrating the issue.
Application is linked with AddressBook.framework, and only does, in applicationDidFinishLaunching:

    [ [ NSDistributedNotificationCenter defaultCenter ] postNotificationName: @"foo" object: @"bar" ];

Complete crash report is also attached, as well as the faulty generated binary.

--------------------------------------------------

Steps to Reproduce:

Use some methods from NSDistributedNotificationCenter in an app linked with the AddressBook framework.

--------------------------------------------------

Expected Results:

App should launch...

--------------------------------------------------

Observed Results:

Application crashes with a Dyld error, because it cannot find the NSDistributedNotificationCenter class symbol in AddressBook.framework.

--------------------------------------------------

Version:

Xcode 9 beta 3 (9M174d)
macOS 10.13 Beta (17A306f)
