Re: Pasteboards and NSSecureCoding

Thanks for your detailed comments! Something I’ve realised through this is that you need to be really careful about upgrading your system on a development machine. Going from 10.12 to 10.13 - and finding that pasteboard functions compile just fine but no longer work - is almost as big a jump

Re: Pasteboards and NSSecureCoding

It seems that I can write: let array = decoder.decodeObject(of: [NSArray.self], forKey: kArrayKey) as! [Int] But shouldn't I be able to specify that this is an array of Ints, and not just an array of anything? I should probably avoid force unwrapping - this ought to be a failable
