# Swift Combine: last() operator. Unknown but useful operator.

Let’s learn about the `last()`

operator. You can pretty much guess the last operator is going to find the the last value in the sequence that satisfies a particular condition that is set by you.

# find the last element using last()

`let numbers = (1...9).publisher `

numbers

.last(where: { $0 % 2 == 0 })

.sink {

print($0) // 8

}

I created numbers with range from 1 to 9 and made it a publisher. You can clearly see that `last()`

operator takes a closure where you must define your condition. Here in this example, I wanted to find the last even number in the sequence.

This is the whole purpose of `last()`

operator. **It is going to wait until the last value has been checked and then simply return the value which satisfies your condition.**

# Conclusion

`last()`

operator searches for the entire sequence to find the last element that meets your criteria.
