![]() ![]() Information including CPU usage, top memory processes, memory storage, load averages, and disk space will all be stored one click away. IStat Menus has a notification widget which allows you to tuck your tracked stats in the Notification Center. There are unique ways to style the menu bar icons, menu drop down lists, and generated graphs. Version 6 also boasts more color and theme options than ever before. iStat Menus can pull up the weather on your current location or search the weather for nearly any city worldwide. You can also pull up a detailed weekly weather overview and hourly forecast. IStat Menus has a new weather monitoring tool that allows you to view current weather conditions on your menu bar. You can receive notifications on things like a change in public IP, a spike in CPU usage, a lack of internet connection, or a near-infinite combination of other customizable data. You can choose your notifications based on GPU, CPU, disks, memory, network connections, battery life, sensors, general power, and weather updates. IStat Menus has a comprehensive notifications system that can notify you of a wide range of potential events. It's also gone through multiple upgrades, each upgrade improving upon the previous version and adding multiple new features. IStat Menus has a huge variety of personalized data types that it can monitor. The goal of iStat Menus is to create customizable notifications, menu bars, and monitors to suit each individual Mac user's uniq. For now, we use it to store the default coordinates of the location we fetch weather data for.IStat Menus is an advanced system monitor created to monitor your Mac. This struct stores several default values that come in handy. I have added another struct to Configuration.swift, Defaults. Return BaseURL.appendingPathComponent(APIKey) It combines the value of BaseURL and APIKey. This computed property returns the base URL for an authenticated request. ![]() Moreover, the application we are creating would be of little use if BaseURL would not contain a valid value.īefore we move on, I would like to add a computed property to the API struct. That said, since we are responsible for the value of BaseURL and we know that it is a valid URL at compile time, I consider it safe to force unwrap the value we assign to BaseURL. I always emphasize to be careful with the use of forced unwrapped values. Note that we force unwrap the value that is assigned to BaseURL. ![]() Static let APIKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" You can create a free Dark Sky developer account on the Dark Sky website. If you want to follow along, replace the value of APIKey with the API key of your Dark Sky developer account. Note that both constants are static properties. We declare a BaseURL and an APIKey constant. We use the API struct to namespace constants that are related to the Dark Sky API. Add an empty file to the group and name it Configuration.swift.Īdd an import statement for the Foundation framework and create a structure, API. In the Project Navigator, create a new group, Configuration, and a corresponding folder for the group. This is easy to solve with constants, but Swift adds a dash of elegance to this approach that I am particularly fond of. Why is that necessary? I have a fierce allergy for hardcoded values and string literals, especially if they are scattered throughout the codebase of a project. You can use structures or enumerations to create namespaces for constants and convenience methods to access them. Yesterday, I wrote about an undocumented side effect of nested types in Swift. ![]() If you want to follow along, clone or download the project from GitHub. In this tutorial, I also show you how to organize the configuration we need to accomplish this. This tutorial focuses on fetching weather data from Dark Sky and deserializing it, ready to use in the application. As I mentioned earlier, the application we are building uses the Dark Sky API to fetch data for a particular location. We built a basic user interface in the previous tutorial and it is now time to fetch weather data that we can show to the user. ![]()
