Mutable Set SwiftUI remove all

XMLWordPrintableJSON

      Problem

      We are trying to use the 'removeAll' method for a mutable set in a SwiftUI context, if we do for example:

      mySet.removeAll()

      the app crashes because it is not in a transaction

      but if we do

      $mySet.removeAll()

      removeAll has not been implemented

      Solution

      could we add another method to this extension:

      @available(iOS 13.0, macOS 10.15, tvOS 13.0, watchOS 6.0, *)
public extension BoundCollection where Value == MutableSet<Element> {
    /// :nodoc:
    func remove(_ element: Value.Element) {
        write { mutableSet in
            mutableSet.remove(element)
        }
    }
    /// :nodoc:
    func insert(_ value: Value.Element) {
        write { mutableSet in
            mutableSet.insert(value)
        }
    }
}

      to implement removeAll like insert and remove?

      Alternatives

      for now we have written an extension on the SwiftUI binding that sets the wrapped value to an empty set:

      public extension Binding<MutableSet<String>> {
  func removeAll() {
    self.wrappedValue = MutableSet()
  }
}

      How important is this improvement for you?

      I would like to have it but have a workaround

      Feature would mainly be used with

      Local Database only
