## Declaration

@discardableResult mutating func remove(_ member: Self.Element) -> Self.Element?

#### Summary

Removes the given element and all elements subsumed by it.
In the following example, the .priority shipping option is removed from
the options option set. Attempting to remove the same shipping option
a second time results in nil, because options no longer contains
.priority as a member.
    var options: ShippingOptions = [.secondDay, .priority]
    let priorityOption = options.remove(.priority)
    print(priorityOption == .priority)
    // Prints "true"
    print(options.remove(.priority))
    // Prints "nil"
In the next example, the .express element is passed to remove(_:).
Although .express is not a member of options, .express subsumes
the remaining .secondDay element of the option set. Therefore,
options is emptied and the intersection between .express and
options is returned.
    let expressOption = options.remove(.express)
    print(expressOption == .express)
    // Prints "false"
    print(expressOption == .secondDay)
    // Prints "true"

#### Returns

The intersection of [member] and the set, if the
  intersection was nonempty; otherwise, nil.

### Parameters

| Name | Type | Summary |
| --- | --- | --- |
| member | Self.Element | The element of the set to remove. |
