In this Swift programming tutorial, you are going to learn how to find the maximum and minimum values from an integer-type array.
Swift already comes with the in-built
min() methods. We can use these methods to perform our tasks. Both of these methods work similarly.
max method will help us to find the largest value. On the other hand, the
min method will get the integer smallest value.
Suppose, we have an integer type array that contains some integer type values in it. Now we have to find the maximum value among the items.
Below is the code example in Swift for getting the maximum value from the array:
let valuesArray = [13, 22, 54, 7, 19] let maxVal = valuesArray.max() print( "maximum value is \(maxVal!)" )
In the above code, we have used the Swift
max() method to get the maximum value from our array.
Just like the above example, we can also get the minimum array item value. In this case, we have to use the min() method. Below is how we can do it:
let valuesArray = [13, 22, 54, 7, 19] let maxVal = valuesArray.min() print( "maximum value is \(maxVal!)" )
You can see that, in both of the above programs, we have used the “
!” in our program. This is because we have to get only the integer value.
I hope, you have understood how to use the
max() and the
min() method in Swift programming.
