The release notes for 10.13 say:
If your application is linked on macOS 10.13 SDK or later, classes that return
NSPasteboardReadingAsKeyedArchive from readingOptionsForType:pasteboard: must
support secure coding, and will be decoded with a coder that requires secure
coding.
So I’m updating some of my classes to support NSSecureCoding, and I’m having
trouble figuring out how I should decode an array of Ints.
Previously, I had:
let array = decoder.decodeObject(forKey: kArrayKey) as! [Int]
I think that I need to replace that with something like:
let array = decoder.decodeObject(of: allowedClasses, forKey: kArrayKey) as!
[Int]
but I can’t work out how to define allowedClasses.

So I’ve tried:
let allowedClasses = NSSet(objects: NSArray.self, Int.self)
But I get an error: Cannot invoke 'decodeObject' with an argument list of type
'(of: NSSet, forKey: String)’
I also think there should be a way of doing this that uses Array and Set rather
than NSArray and NSSet
