Higher order functions in Swift are extremely powerful tools to have in your developer toolkit.
And Higher order functions are functions that operate on other functions by taking function as argument or returning function.
In this tutorial, I’m going to present the most famous and mostly used higher order functions in iOS swift.
So use of this we can achieve the solution in a quick way.
Because of the higher-order function, we can save our time.
Returns an array containing the results of mapping the given closure over the sequence’s elements.
Sorted using the given predicate as the comparison between elements.
So use of this function you can sort the array in an easy way
Returns an array containing, in order, the elements of the sequence that satisfy the given predicate.
So this filters the array in an easy way. because of the filter function, we can create the optimized code.
Returns the result of combining the elements of the sequence using the given closure
So use the reduce we can add the array element in fast way
-> Remove All
Removes all the elements that satisfy the given predicate.
Use this method to remove every element in a collection that meets particular criteria
And this works very fast and provides a very quick solution.
Returns the bool value if any array contains data or not with a given predicate.
A closure that takes an element of the sequence as its argument and returns a Boolean value that indicates whether the passed element represents a match.
