How to convert optional NSData to optional Bool

Question

I have a NSData variable called: isMaxVersionEnabled? it is a optional.

I want to convert isMaxVersionEnabled to an optional Bool.

So far I have figured out how to convert a NSData value to a bool like this:

NSKeyedUnarchiver.unarchiveObjectWithData(<NSData value>)

but I am not sure how to utilize it because the input must be unwrapped and that is a problem since isMaxVersionEnabled might be nil.

Answer 1

You can get NSData Int value(very first bytes) and compare with 0 to get bool value

var boolValue = false
var value: Int = 0
isMaxVersionEnabled?.getBytes(&value, length: sizeof(Int))
if value != 0 {
    boolValue = true
}

print(boolValue)
