MSPasteboardManager.writeXX seems to be broken on Sketch 70.5

Calling MSPasteboardManager.writePasteboardLayers_toPasteboard like so:

// 'layer' is a native sketch object
MSPasteboardManager.writePasteboardLayers_toPasteboard(
    MSPasteboardLayers.pasteboardLayersWithLayers([layer]),
    NSPasteboard.pasteboardWithName(NSDragPboard));

seems to be broken, throwing an Objective-C exception:

NSInvalidArgumentException *** -[NSMutableArray addObjectsFromArray:]: array argument is not an NSArray

...

Any ideas anyone :-)

romannurik Oh and yes, passing an empty array ([]) throws the same error as [layer].

I've found a workaround, basically getting access to the MSPasteboardLayersReaderWriter and using its writeData_toPasteboard method directly:

let layerWriter = Array.from(NSApp.delegate().pasteboardManager().writers())
    .find(x => String(x.className()) === 'MSPasteboardLayersReaderWriter');
layerWriter.writeData_toPasteboard(
    MSPasteboardLayers.pasteboardLayersWithLayers([layer]),
    NSPasteboard.pasteboardWithName(NSDragPboard));

Huh thats kinda strange… I imagine you are doing some drag and drop stuff eh? I haven't had a chance to work with that yet. I think the Sketch folks probably have the most insight as to what might have changed with that internal method.
