Checking array is empty
To check if a array is empty or not, we can use the built-in isEmpty property in Swift.
The isEmpty instance property returns true if an array is empty; otherwise returns false.
Here is an example:
var names:[String] = []print(names.isEmpty)
Output:
true
or we can also check it like this:
var names:[String] = []if(names.count == 0){ print("names array is empty")}else{ print("names array is not empty")}Output:
"names array is empty"
