how to get type of a variable in swift

Question

Every variable in swift has a type.

var c: Int = 0 // type is Int

var d: (Int,(String,Double)) // type is (Int,(String,Double))

how can I get type of a variable. See example below.

func retSomeThing ()-> ((Int,(String,b: Int))){
    return(10,("something",b: 56))
}

var a = retSomeThing()
var b = retSomeThing()
if (a.type.equal(b.type)) { // my problem is here.
    print("Hala Madrid")
}

I used this code

a.dynamicType

But it has shown : value of tuple type '(Int, (String, b: Int))' has no member 'dynamicType'

I don't see how your example ilustrates the need to get the dynamic types of `a` and `b` – you already know they're the same type. — Hamish, May 20 '17 at 12:20
@Hamish Yes I know the type in this example. But I need to get type of tuple variables. — Amir Shabani, May 20 '17 at 12:22

You can check the type of any variable using is keyword.

var a = 0
var b = "demo"
if (a is Int) { 
    print("It's an Int")
}

if (b is String) { 
    print("It's a String")
}

To compare any complex type, you can use below method:

if type(of: abc) == type(of: def) {
    print("matching type")
} else {
    print("something else")
}

'is' only is not suitable for tuple valuses – Amir Shabani May 20 '17 at 12:23
