Swift Arrays: Loop
Swift Arrays: Loop
Use for-in to loop values.
Use enumerated() for index and value.
Loop Elements
Loop values with for-in, or use enumerated() for index and value.
Example
let fruits = ["Apple", "Banana", "Cherry"]
for fruit in fruits {
print(fruit)
}
for (i, fruit) in fruits.enumerated() {
print("\(i): \(fruit)")
}Get index and value with enumerated().
forEach
Use forEach for a functional style loop. It reads values but cannot use break/continue.
Example
let fruits = ["Apple", "Banana", "Cherry"]
fruits.forEach { print($0) }
fruits.enumerated().forEach { print("\($0.offset): \($0.element)") }
