ProgramGuruTo count the number of occurrences of a specified element in an array in Swift, you can use methods like filter or loops to iterate through the array and count each occurrence.
In this example,
numbers with values 10, 20, 30, 40, 30, 50.filter method to filter elements equal to 30.count property of the filtered array.let numbers = [10, 20, 30, 40, 30, 50]
let count = numbers.filter({ $0 == 30 }).count
print("Number of occurrences of element 30: \(count)")Number of occurrences of element 30: 2
In this example,
fruits with values 'apple', 'banana', 'cherry', 'banana'.count to 0 to store the count of occurrences.count each time element 'banana' is found.count will contain the total count of occurrences of element 'banana'.let fruits = ["apple", "banana", "cherry", "banana"]
var count = 0
for fruit in fruits {
if fruit == "banana" {
count += 1
}
}
print("Number of occurrences of element 'banana': \(count)")Number of occurrences of element 'banana': 2
