Instance MethodSwift


    Removes all the elements that satisfy the given predicate.

    mutating func removeAll(where shouldBeRemoved: (Self.Element) throws -> Bool) rethrows



    A closure that takes an element of the sequence as its argument and returns a Boolean value indicating whether the element should be removed from the collection.


    Use this method to remove every element in a collection that meets particular criteria. The order of the remaining elements is preserved. This example removes all the odd values from an array of numbers:

    var numbers = [5, 6, 7, 8, 9, 10, 11]
    numbers.removeAll(where: { $0 % 2 != 0 })
    // numbers == [6, 8, 10]
