Optional setter

[dral3x]

Hi,

In our code we will generate a json representation of some entities. We would like to have setters that handle optional to NOT output "null" values but simply ignore the key-value all together.

For example, by doing

var json = JSON([String: JSON]())
json["test"] = nil

the result should be {} and not {"test":null}

Is there something already built-in for this?

There hasn't been much activity on this issue for a while so I'm gonna go ahead and consider it fixed. Please let us know it you'd like to reopen it.

@ldiqual As far as I know, it's not fixed. I did an extension to work around this limitation

extension JSON {

    // MARK: Setter with optional
    public mutating func optionalSetter(key: String, value: String?) {

        guard let value = value else {
            return
        }

        self[key].string = value
    }
...
}

Of course I did a function of each data type supported.

I can make a PR if you want to embrace this. Just let me know!

I'd like to see optional setters support as well. @dral3x could you send a PR to try and get this going?

Here it is the PR #784

More than 1 year has passed and this issue is still open.
Is there any problem in integrating the PR I made?

Thanks!

I guess we have all moved to Swift4 support by now :/
