使用UInt8数组作为值的Swift字典

Question

Is it possible to declare a dictionary? Type String as its key, and value with multiple types(String, Int, [UInt8]) ?

Answer 1

First that came my mind:

var content:[UInt8] = [1,2,3]
var arr = [String:Any]()
arr["1"] = 1
arr["2"] = "test"
arr["3"] = content

Or you want to get values with type casted?

UPD: Another solution in my mind was to use generics, but then you should realize your own class or protocol for storaging. And find on stack similiar solution here

Answer 2

You can do what you want using a dictionary of type [String: Any] .

var theDictionary = [String: Any]()
theDictionary["blue"] = "sky"
theDictionary["lucky"] = 7
theDictionary["bytes"] = [UInt8](arrayLiteral: 0x01, 0xFE, 0x54)
