I use 11ty to generate a static website and S3 to host it. This post describes how I set up a workflow in GitHub Actions to build and deploy the website. The workflow uses the AWS - CLI S3 - sync command to transfer the files.
This post describes how to:

This post assumes you already have set up an S3 bucket. If not, please see the Hosting a static website using Amazon S3 guide.

In this post, I will discuss autoscaling PDF images and how to add one to a watchOS project.
The PDF format allows an image to scale without looking fuzzy at different sizes. This format is best used with vector artwork; think icons. Programs like Inkscape, Adobe Illustrator and, Vectornator can export PDF images.
For more details on designing a PDF image see the Image Optimization page in the Human Interface Guidelines for watchOS. It includes the scales used for the different screen sizes.
Setting certain flags in XCode will tell WatchKit to scale the image based on screen size. And so, you have an autoscaling PDF image. This means the project only needs one image for all screen sizes. Otherwise, the project would need multiple scaled image files.

I hit a small milestone recently, I submitted my first app to TestFlight. I thought this process would be quick. Maybe a day or two. A week later I finally had a working app on TestFlight. During that time I learned much about crash logs and debugging. Here is my story.

I wrote a unit test that used the XCTUnwrap function. This feature was added in XCode 11 and
“Asserts that an expression is not nil and returns the unwrapped value.”
However, when I pushed my code to GitHub, the build broke with the following error.
