Variables with a value check if nil Swift 5.1

If you don’t want to set a default value to your variable you will have to write your variable like this:

var myNilVariable: String?

// now you can test whether the variable has a value or not
if myNilVariable == nil
{
    print("nothing there")
}

// though if you assign a string variable to this then you will not be able to check if it is nil
// unless you have the ? After the variables declaration String

var myNilVariable:String? = "Hi"

// now you can test whether the variable has a value or not
if myNilVariable == nil
{
    print("nothing there")
}
