Codable support

Is your feature request related to a problem?

You don't support Codable when using capture for events.

Describe the solution you'd like

Getting error: key does not conform to NSCoding and cannot be serialized for delivery.

Describe alternatives you've considered

Allow Codable

@JoeFerrucci do you mean https://developer.apple.com/documentation/swift/codable ?

[JoeFerrucci]

Yes, that is the one. When I try to pass a dictionary into capture(event:properties:) it fails with that error.

Here is a trivial example to help highlight it

struct MyType: Codable {}

posthog?.capture("My Event", properties: ["somekey": MyType()])

This yields the error. Technically PostHog SDK only needs to support Encodable; it doesn't need to be Decodable

Note: the error appears at runtime when you try to send the data over the wire; it's not a compile time error.

We're currently rewriting the iOS SDK and we'll consider this use case, thanks for the context. Edit: Consider using the customstringconvertible as well.
