updateIfExists pull request?

[Kondamon]

Hey all,

thanks for the great framework. I would be interested in having an update function only if an object already exists in the array. Otherwise the update does nothing. If you think this is a useful addition I would create a merge request for this feature.

public mutating func updateIfExists(_ item: Element) -> Element?

It would be great to have this option!

I believe you can use optional-chaining to qualify subscript assignment:

array[id: element.id]? = element

Does this work for you?

[alinless]

Yes, that works! Didn't know about this feature. Thank you!
