realm. remove objects from ListBase

I have different realm models. They have List properties. I want to make universal way for removing objects from List properties. So I did the following:

if let list = self[property.name] as? ListBase {
    list._rlmArray.removeAllObjects()
}

but this just clear list property, without deleting objects from realm. The only way I've found is:

if let list = self[property.name] as? ListBase {

    while list.count > 0 {
        let object = list._rlmArray.firstObject()
        let any = object as Any

        if let theObject = any as? Object {
            realm.delete(theObject)
        }
    }
}

Code above works and doesn't generate any warning. But it looks ugly.

When Realm removed ListBase the following solution worked for me. Use RLMSwiftCollectionBase instead of ListBase.

You can use dynamicList(_ propertyName: String) to retrieve List property by name instead subscript.

if property.type == .array {
    try! realm?.write {
        realm?.delete(dynamicList(property.name))
    }
}
