Filter Queries - Example Use Cases

Here are a few example use cases, these use cases combine filter with other parameters to make useful API queries. The syntax for any of this may change between now, implementation, and release - they're meant as illustrative examples :)

Fetch 3 posts with tags which match 'photo' or 'video' and aren't the post with id 5.

api.posts.browse({filter: "tags:[photo, video] + id:-5", limit="3"});

GET /api/posts?filter=tags%3A%5Bphoto%2Cvideo%5D%2Bid%3A-5&limit=3

Refreshing SwiftUI on changes within objects in a collection.

How to approach updating UI for changes within objects held within a collection? After experimenting a bit, I think there are basically two approaches.

1. The conformance to BindableObject by the object that contains the collection needs to be deep and not shallow. It needs to fire didChange if the collection, or anything recursively within the collection, changes. In my example from yesterday, this means that MainViewModel would need to figure out how to fire didChange if anything within any of its existing rows changes - not just changes to the collection itself. or
2. The parent/container can have shallow conformance to BindableObject if the row model themselves conform to BindableObject and the row view declares the dependency with @ObjectBinding.

You must do one or the other if you want a row to refresh when isTyping changes value. I suspect that in the general case, #2 will be simpler.

    init(_ hex: UInt32, opacity:Double = 1.0) {
        let red = Double((hex & 0xff0000) >> 16) / 255.0
