I'm new to swift and I'm trying to search an array of strings and return a specific value, for example let's say i want to search my array and check if contains mango, if it does then I would like to print that.
var fruitArray: Array = ["Banana", "Apple", "Mango", "Strawberry", "blueberry"]
fruitArray.append("Orange")
for fruits in fruitArray{
print(fruits)
}
You don't need to iterate over the array yourself.
let searchTerm = "Mango"
if fruitArray.contains(searchTerm) {
print(searchTerm)
}
You can use collection's method firstIndex(of:) to find the index of the element on your collection and access the element through subscript or if the index of the element is irrelevant you can use first(where:) to find the first element that matches your element or any predicate you may need:
var fruits = ["Banana", "Apple", "Mango", "Strawberry", "blueberry"]
fruits.append("Orange")
if let firstIndex = fruits.firstIndex(of: "Mango") {
print(fruits[firstIndex]) // Mango
// if you need to replace the fruit
fruits[firstIndex] = "Grape"
print(fruits) // "["Banana", "Apple", "Grape", "Strawberry", "blueberry", "Orange"]\n"
}
or
if let firstMatch = fruits.first(where: { $0.hasSuffix("go")}) {
print(firstMatch) // Mango
}
