Terms of Use. Email Address. IOS developer based in barcelona. Jul Alberto Moral. A package is simply a collection of Swift source code files and a metadata, or manifest , file called Package. Download the project materials using the Download Materials button at the top or bottom of this tutorial.
Open the starter project in Xcode. Build and run. Within my team, the same person always volunteers to start a stand-up or scribe meeting notes. Ideally, everyone should share this load, so I started spinning a pen on the table to pick somebody at random for each task.
Tap the pen. A slider controls the number of resting positions under the pen. These represent the number of people in your team. You can access a settings screen via the gear icon in the navigation bar.
There you can set the style of the pen. Apple has acknowledged the bug and is working on a fix. Workarounds are available, but they add complexity to the app. Navigate to the settings screen and select the fountain pen.
Now navigate to the main screen. The body property defines a VStack. What if you wanted to add more pen types later, perhaps triggered by an in-app purchase or as a reward after unlocking extra functionality? Select an Empty file underneath the Other heading. Click Next , name your file pens. This file will contain the data about the available pens. Each new pen starts with a dash character and contains three properties: a key , label and url. But how to parse the YAML? You could write your own YAML parsing code, but surely somebody has already done this.
This is where SwiftPM comes in. The next screen asks you to define the package options for this package. For now, select the default which accepts any version of the package up to the next major version. As of writing this is therefore from 2. Click Next. Click Finish. Select the PenOfDestiny target and note that Yams is automatically linked as a framework to your project target.
Build and run just to check that everything is still working. Yams will now be built as well and linked to your app.
Open SettingsStore. This class defines a simple data store that saves the selected pen to UserDefaults as well as a function to get all available pens and the array of pens themselves. Next, delete the availablePens static variable and replace the contents of getAvailablePens with the following:. Build and run the app. Navigate to the settings screen and confirm that the three pens from before are still available. No code is perfect and all code changes over time, either to add new functionality or to fix bugs.
And more importantly, how do you know if an update is likely to break your project? All Swift packages should adhere to semantic versioning. Every time a package is released it has a version number, made up of three sections in the following format: major. For example, if a package is currently at version 3. The package will be imported into Xcode after which you can use it in the main. This is needed to be able to use our executable as an actual command-line tool from the terminal. As we can now make use of the ArgumentParser framework we can start writing the code to generate the banners.
This protocol allows us to add a command configuration in which we can configure things like the abstract, subcommands, and the command name. The command name is by default derived by converting the name of the command type to hyphen-separated lowercase words.
In our case, this is set to banner , which is perfect! The Banner. Arguments will be parsed and handled accordingly. The Generate struct conforms to the ParsableCommand which allows us again to define a configuration with a describing abstract. Each property wrapper takes different types of arguments and allows us to set a help description.
We can set a default value for optional arguments and we can make use of a flag to enable specific configurations like verbose logging. Both the Option and Flag property wrapper allows you to set a name type. All we have to do is to run it programmatically, and assert that it created a file with the name that was specified.
First add a test module to your Package. I hope you enjoyed this post. Also, let me know if you have any comments or questions, along with requests for any future weekly blog posts on Twitter johnsundell.
