I have defined a class :
class Item: NSObject, NSSecureCoding {
var name : String = ""
var color : ColorTag = .black // defined as enum ColorTag: Int
var value : Int = 0
static var supportsSecureCoding: Bool {
return true
}
Its decoder includes the following print statement to start:
required init(coder decoder: NSCoder) {
print(#function, "item should not be nil", decoder.decodeObject(of: Item.self, forKey: someKey))
Another class uses it:
class AllItems: NSObject, NSSecureCoding {
var allItems : [Item]?
static var supportsSecureCoding: Bool {
return true
}
and decodes as follows
required init(coder decoder: NSCoder) {
super.init() // Not sure it is necessary
allItems = decoder.decodeObject(of: NSArray.self, forKey: mykey) as? [Item]
print(#function, allItems) // <<-- get nil
}
I note:
decoder returns nil at line 5
I have tried to change to
decoder.decodeObject(of: [NSArray.self, NSString.self, NSColor.self, NSNumber.self], forKey: mykey))
Still get nil
And, decoder of class Item is not called (no print in the log)
What am I missing ?
