![]() □ It handles all tedious tasks, like generating screenshots, dealing with code signing, and releasing your application.įastlane has been an amazing tool to dabble for developers in order to automate their deployment workflows and easy to integrate in applications by virtue of its clear documentation. It could include such tasks as getting provisional profiles, updating our project with resources, etc.Fastlane is the easiest way to automate beta deployments and releases for your iOS and Android apps. The Dev subcommand is intended for our team. We can obtain sensitive info from the execution environment like this: import Foundation Subcommands could contain sensitive info usage, like API keys or passwords for production certificates. We intend to use CI subcommand in our continuous integration system. Static var configuration = CommandConfiguration( Habramator contains 2 subcommands which might look like this: import Foundation Then we define our subcommands if needed. If your CLI doesn't need subcommands or you need a default action, override the func run() throws for that at the Habramator struct level. In this case, the habramator is our CLI entry point. If you're building your CLI as a package, you'll need a attribute added to the Habramator struct. Static let configuration = CommandConfiguration(Ībstract: "Command line tools for your iOS project",įirst, we define our app's main command. Here's my example of using CLI to test the iOS app on pull requests.Īdding app`s entry point import Foundation With that dependency in place, we could write our reusable commands and subcommands in either object-oriented or protocol-oriented way. At the same time, we are maintaining our CLI code readable and structured. Swift Argument Parser is supported by Apple itself and uses all the latest Swift features like property wrappers and structured concurrency. Swift package manager would be a great option nowadays. Then add a Swift Argument Parser framework using your dependency manager of choice. Create an Xcode project with a command line tool template. The fun wayīut if you plan to build a thorough CLI with subcommands and arguments there is a nicer way. The final script file will look like this: #!/usr/bin/env swift We can consider adding a instead of u for our developer scripts. ![]() Where u is the owner and x is the execution permission. We should also make our file executable and give it all the needed permissions to run: It implies you have Xcode command line tools or a separate swift runtime installed. We only need to add a swift environment to our script like so: #!/usr/bin/env swift This simple example wouldn't need compiling and could be executed as a script. Let num1 = Int(arguments), let num2 = Int(arguments) Without any additional dependencies, we could create a Script.swift file and add code like this: import Foundation The first alternative would be to create a project in Xcode and use the Command line tool template. It's currently in beta, and most times it's just a bridge to Ruby code. ![]() As a multipurpose language, Swift allows us to write not only apps, but also backend, scripts, and, specifically, command line tools.Īn interesting note on Fastlane – they are adding the Swift version of their tools. To counter that, we can use our currently most popular language in iOS – Swift. There are 200+ lines in Gemfile.lock describing dependencies. Setting up a Ruby environment could be quite tedious and require additional devs' expertise to write and support those scripts.Īlso, Fastlane comes with a lot of dependencies itself. However, there's a great chance you considered moving away from Fastlane to avoid learning Ruby and to lower the entry threshold for your developers. Fastlane is a great tool, convenient and fairly easy to use, and a lot of effort came into building it. The most popular CLI for app signing and build automation is, without a doubt, Fastlane, which was initially written in Ruby. ![]() In iOS, we usually use scripting languages like Bash or Ruby to build those CLIs and automate mundane tasks. Command-line interfaces (CLI) are a common way to use applications.
