WXKDarkSky

This Swift package is a Codable layer over the Dark Sky API for quick and easy access to API response objects. It’s super straightforward and directly modeled after the Dark Sky API docs.

This package is written in pure Swift, and it has no dependencies, so you don’t need to worry about conflicts or anything like that.

Compatibility

WXKDarkSky should work great with Swift 5.1.

Installation

Install WXKDarkSky via Swift Package Manager, or if you really don’t want to, you can also import the source files manually. CocoaPods and Carthage are not officially supported. Use them at your own risk.

Swift Package Manager (recommended)

Of course, you’ll need to add this package as a dependency in Swift Package Manager:

.package(url: "https://github.com/loopwxservices/WXKDarkSky.git", from: "4.0.0")

Then, just be sure to add "WXKDarkSky" as a dependency in the targets section.

Manual

Just get the source files out of the Sources folder and drag them into your Xcode project, and add them to any relevant targets. Just make sure to keep updated should changes be made to the Dark Sky API.

Usage

The DarkSkyResponse object structure should perfectly match that of the documented response format for ease of reference. In keeping with the documentation, nearly everything is an optional value, even if it is frequently included. Absolutely no assumption is made about the availability of weather data!

Build URLs for networking

WXKDarkSky does not include its own networking code, but you can build a URL for a request like so:

// Set up the request with your API key.
let request = DarkSkyRequest(key: "YOUR_API_KEY_HERE")
// Specify the point to use in the request
let point = DarkSkyRequest.Point(43.02, -108.38)

// Build a URL to use for a request using the default options
if let url = request.buildURL(point: point) {
    // ...
}

Your API key should never be hard-coded into a public product like an app; this puts it at risk of being compromised and, should it become compromised, will leave you with no way to replace the API key in code that already shipped.

Request configuration

The buildURL method supports two additional parameters for configuring your request. It takes an optional time parameter which defaults to nil, to which you may pass a Date object for a Time Machine request.

You can also create a DarkSkyRequest.Options object to specify the following options for the Dark Sky API:

• exclude: Data blocks to exclude from the request.
• extendHourly: Whether to extend the hourly forecast to 168 hours instead of 48 hours.
• language: Language to be used in the response.
• units: Units to be used in the response.

A DarkSkyRequest.Options object can be initialized with any combination of the above four. If you do not include one, it will use the default setting. You can also use Options.defaults to access the default options (for example, Options.defaults.extendHourly).

Accessing data from a response

After you obtain data from the Dark Sky API, using WXKDarkSky is very simple:

let data = // the data you retrieved
if let response = DarkSkyResponse(data: data) {
    // Sample to get the current temperature from the decoded JSON
    if let temperature = response.currently.temperature {
        print("Current temperature: " + String(describing: temperature))
    }
} else {
    // Gracefully handle a decoding error...
}
