Question

I want to check if my array is empty or null, and on base of which I want to create a condition for example.

if(array ==  EMPTY){
//do something
}

Answer 1

Swift 3

As in latest version of swift 3 the ability to compare optionals with > and < is not avaliable

It is still possible to compare optionals with ==, so the best way to check if an optional array contains values is:

if array?.isEmpty == false {
    print("There are objects!")
}

as per array count

if array?.count ?? 0 > 0 {
    print("There are objects!")
}

There are other ways also and can be checked here link to the answer
