swift code exemplifying sandy metz style duck types
Sure, here's an example of a Swift code that uses duck typing, in a style similar to that of Sandi Metz:

swift
Copy code
protocol Quackable {
    func quack() -> String
}

// TL;DR: look at this cool thing in swift
let ibsTags = try ibsTagRecords().reduce(into: [Int64: [Int64]]()) {

  // this line here
  $0[$1.ibsID, default: []].append($1.tagID)
  
}

// V1 original

class RawOSMDataTests: QuickSpec {
  override func spec() {
    context("given a RawOSMData") {
      var subject: () -> RawOSMData? = { return nil }

      describe(".decode") {
        var json: String? = ""
        afterEach { json = nil }

        beforeEach {

Customization

<%= f.input :state, :collection => ['SA', 'WA'] %>

<%= f.input :state,
            :as => :radio_buttons,
            :collection => ['SA', 'WA'],

Services Communication Design

TL;DR The plan is to use protobuf for the format. Message calls should be made with gRPC when the client wants a response. High level messages should also be published to the bus. Message calls (events) that don't require a response can just be published to the bus.

There are 3 parts to consider:

• Messaging format
• Client calls that require a response - RPC
• Publishing events - BUS

Messaging Format

The message format must be statically typed, binary, good adoption and have RPC integration.
