__CoatySwift__ is a [Coaty](https://coaty.io/) implementation written in Swift 5.
The CoatySwift package provides the cross-platform implementation targeted at
__iOS__, __iPadOS__,and __macOS__ native applications.

CoatySwift comes with complete API documentation, a developer guide, a tutorial,
and best-practice examples.

## What is Coaty

Using the Coaty [koʊti] framework as a middleware, you can build distributed
applications out of decentrally organized application components, so called
*Coaty agents*, which are loosely coupled and communicate with each other in
(soft) real-time. The main focus is on IoT prosumer scenarios where smart agents
act in an autonomous, collaborative, and ad-hoc fashion. Coaty agents can run on
IoT devices, mobile devices, in microservices, cloud or backend services.

Coaty provides a production-ready application and communication layer foundation
for building collaborative IoT applications in an easy-to-use yet powerful and
efficient way. The key properties of the CoatySwift framework include:

* a lightweight and modular object-oriented software architecture favoring a
  resource-oriented and declarative programming style,
* standardized event based communication patterns on top of an open
  publish-subscribe messaging protocol (currently [MQTT](https://mqtt.org)),
* and a platform-agnostic, extensible object model to discover, distribute,
  share, query, and persist hierarchically typed data.

## Learn how to use

If you are new to CoatySwift and would like to learn more, we recommend checking
out the following resources:

-   [Tutorial](https://coatyio.github.io/coaty-swift/tutorial/index.html) -
    shows how to set up a minimal CoatySwift app.
-   [Developer
    Guide](https://coatyio.github.io/coaty-swift/man/developer-guide/) -
    explains how to develop a CoatySwift app.
-   [API Documentation](https://coatyio.github.io/coaty-swift/api/index.html) -
    the source code documentation of public types and members of the CoatySwift
    framework.
-   [Design
    Rationale](https://coatyio.github.io/coaty-swift/man/design-rationale/) - in
    case you want to know why certain things have been implemented in a
    particular way in the CoatySwift implementation.

## Getting started

Coaty Swift now supports both Swift Package Manager and CocoaPods!

It is compatible with the the following deployment targets:

| Deployment Target | Compatibility |
| ----------------- | ------------- |
| iOS               | 9.0+          |
| macOS             | 10.14+        |

### CocoaPods

To use Coaty Swift with Cocoapods you need XCode 10.2 or higher. CoatySwift is
available through [CocoaPods](https://cocoapods.org). Ensure you have installed
**at least** version `1.8.4` of CocoaPods, i.e. running `pod --version` should
yield `1.8.4` or higher.

You can add the CoatySwift pod to the Podfile of your app as follows:

```ruby
target 'MyApp' do
  pod 'CoatySwift', '~> 2.4.0'
end
```

Then, run a `pod install`.

### Swift Package Manager

To use CoatySwift with Swift Package Manager you need XCode 11.0 or higher. The
Swift Package Manager is a package manager integrated into the swift compiler.

Once you have your Swift package set up, add CoatySwift by modifying the
`dependencies` attribute in your `Package.swift` file.

```swift
dependencies: [
    .package(url: "https://github.com/coatyio/coaty-swift", from: "2.4.0"),
]
```

## Examples

If you want a short, concise look into CoatySwift, feel free to check out the
[CoatySwift Tutorial](https://coatyio.github.io/coaty-swift/tutorial/index.html)
with a step-by-step guide on how to set up a basic CoatySwift application.

The source code of this tutorial can be found in the
[CoatySwiftExample](https://github.com/coatyio/coaty-swift/tree/master/Example)
Xcode project inside of the CoatySwift repo. Just clone the repo, open the
`Example.xcodeproj` file and run the project on a device / simulator.

You can find additional examples in the `swift` sections of the
[coaty-examples](https://github.com/coatyio/coaty-examples) repo on GitHub. You
will find the following Xcode projects there: `Hello World` and `Remote
Operations`. They are interoperable with the corresponding Coaty JS examples and
intended to be used along with them. These projects can serve as blueprints for
how to design CoatySwift applications.

## Testing

If you want to run unit tests on CoatySwift, look at
(https://github.com/coatyio/coaty-swift/tree/master/Tests) Xcode target of the
CoatySwift repo. Just clone the repo and wait for XCode to fetch all of the
required dependencies. Then select the Test Navigator in Navigator View, enable
chosen tests and run them. Plese note that an MQTT Broker must be present to
test some of the functionality (running on `localhost:1883`) - you may use the
Coaty Development Broker, as described in e.g.
[coaty-examples/hello-world/js](https://github.com/coatyio/coaty-examples/tree/master/hello-world/js).
