Getting Started With Vapor 3 Part 2: Vapor App Structure

July 5, 2018 | Swift, Server-Side Swift, Vapor, macOS

In Part 1 we saw how to install Vapor and create an Xcode project using the default `api` template. That project comes with a lot of code demonstrating the basics of building an API in Vapor. It uses SQLite as the database and a `Todo` model and controller as an example. Our app will eventually use PostgreSQL . . .

Getting Started With Vapor 3 Part 1: Installing Vapor and Creating A Project

Vapor is a web framework for Swift. It runs on macOS, iOS, and Linux, and can be used to build websites, web applications, and APIs. Frameworks like Vapor make it possible to build entire products in Swift, including a backend, web app, marketing site, and Apple device app (iOS, macOS, tvOS, watchOS).

Understanding Hashable, Equatable, and Set Membership

July 1, 2018 | Swift, Protocols, Collections, iOS, macOS, tvOS, watchOS

The `Hashable` protocol in the Swift Standard Library allows us to use our own custom types as a key in a dictionary or as a member of a set. Conforming to `Hashable` where appropriate can make our code safer and improve performance. However, it's important to understand how `Hashable` and `Equatable` work together . . .

Observing Real-Time Ouput From Shell Commands In A Swift Script

In the last tutorial, we saw how to generate code coverage reports using the new `xccov` tool. Part of that process is using the `xcodebuild` command to build a project with code coverage enabled. We ran that command directly in Terminal, but we could also run `xcodebuild` in a Swift script. The problem is `xcodebuild` takes time, and . . .

xccov: Generating Code Coverage Reports

June 21, 2018 | Swift, Unit Testing, Scripting, iOS, macOS, tvOS, watchOS

With the release of Xcode 9.3, Apple included a new command line tool called "xccov". It can be used to view code coverage reports as JSON, which can then be used to automate code coverage workflows. In this tutorial we'll see how to generate and view code coverage reports. We'll then write a Swift script to process the report.
