Snapshot testing for iOS apps in Xcode Cloud

Snapshot testing is a useful testing strategy for iOS apps. PointFree’s snapshot testing library (https://github.com/pointfreeco/swift-...) is excellent to create these kinds of tests, but when using Xcode Cloud as CI provider, this library doesn’t work out of the box with it.

In this video I will show why snapshot testing is useful and how to overcome the problems of integration with Xcode Cloud.

The original inspiration for this video was taken from http://jaanus.com/snapshot-testing-xc... where I expanded with my own explanations and approach

As part of the examples I’ve prepared 2 pull request for this video:

1. A minimum approach on how I would fix snapshots testing integration with Xcode Cloud (https://github.com/fespinoza/sample-j...)
2. A more complete approach with utility types that I would use in real projects (https://github.com/fespinoza/sample-j...)

There also some other tricks when it comes to make SwiftUI views easier to preview/snapshot test that can be found in the repository which I may make a video about if people are interested and comment below 👇
