Exception in IKImageBrowserView in macOS 10.13 GM

I've got a fairly simply application, with IKImageBrowserView embedded in NSScrollView, as is the most common case. When running on macOS 10.13 High Sierra GM and whenever the IKImageBrowserView is presented and there are enough items in it to make it scrollable, it throws and exception with the following stack trace:

NSInvalidArgumentException

There's really nothing special in the implementation. IKImageBrowserDataSource mrotocol methods looks something like

- (NSUInteger)numberOfItemsInImageBrowser:(IKImageBrowserView *)aBrowser
{
    return [myItems count];
}
- (id)imageBrowser:(IKImageBrowserView *)aBrowser itemAtIndex:(NSUInteger)anIndex
{
    return myItems[anIndex];
}

and items implement IKImageBrowserItem also in a very simple way:

- (NSString *)imageUID
{
    return [self  identifier];
}
- (NSString *)imageRepresentationType
{
    return IKImageBrowserNSImageRepresentationType;
}
- (id)imageRepresentation
{
    return [self image];
}
- (NSString *)imageTitle
{
    return [self displayName];
}
- (BOOL)isSelectable
{
    return YES;
}
- (NSImage *)image
{
    if (!_image)
    {
        NSImage *image = [[NSImage alloc] initWithSize:NSMakeSize(128.0, 128.0)];
        [image lockFocus];
        NSRect imageRect = NSMakeRect(.0, .0, 128.0, 128.0);
        [[NSColor redColor] set];
        [NSBezierPath fillRect:imageRect];
        [[NSColor blackColor] set];
        [NSBezierPath strokeRect:imageRect];
        [image unlockFocus];

        [self setImage:image];
    }
    return _image;
}

The UI is implemented using xib file, not a storyboard. Even Apple's official sample code available here suffers from the same issue.

Have anyone find a workaround for this issue. It looks like a bug in the SDK.

Thanks,
