How to remove an element of a given value from an array in Swift

Question

I want to remove all elements of value x from an array that contains x, y and z elements

let arr = [\'a\', \'b\', \'c\', \'b\']

How can I r

Answer 1

If you need to modify initial array, you can use the function removeAll(where:) that is available in Swift 4.2/Xcode 10:

var arr = ["a", "b", "c", "b"]
arr.removeAll(where: { $0 == "b" })
print(arr) // output is ["a", "c"]

However, if you are using Xcode 9 you can find this function in Xcode9to10Preparation (this library provides implementations of some new functions from Xcode 10).
