Converting Boolean value to Integer value in swift 3

Question

I was converting from swift 2 to swift 3. I noticed that I cannot convert a boolean value to integer value in swift 3 :\\ .

let p1 = (\"a\" == \"a\") //true
         


        

Answer 1

Swift 5

Bool -> Int

extension Bool {
    var intValue: Int {
        return self ? 1 : 0
    }
}

Int -> Bool

extension Int {
    var boolValue: Bool {
        return self != 0 
    }
}

Answer 2

Tested in swift 3.2 and swift 4

There is not need to convert it into Int

Try this -

let p1 = ("a" == "a") //true

print(true)           //"true\n"
print(p1)             //"true\n"

Int(true)             //1

print(NSNumber(value: p1))   

Answer 3

You could use hashValue property:

let active = true
active.hashValue // returns 1
active = false
active.hashValue // returns 0

Answer 4

let boolAsInt = <#your bool#> ? 1 : 0

Answer 5

Try this,

let p1 = ("a" == "a") //true
print(true)           //"true\n"
print(p1)             //"true\n"

Int(true)             //1

Int(NSNumber(value:p1)) //1

Answer 6

You could use the ternary operator to convert a Bool to Int:

let result = condition ? 1 : 0

result will be 1 if condition is true, 0 is condition is false.
