Welcome to another issue!
Happy halloween! 👻
One of the scariest things about Halloween is that right under the corner Mariah Carey is hiding. And "All I Want for Christmas Is You" is coming for all of us! 💀
Now let's get serious.
There is one thing I think I shared a few months ago and will share it again. There are times when people unsubscribe from this newsletter (which is totally normal) and say that the texts are generated by AI or similar.
Since I am not a native speaker, some of the texts might sound strange, generic, stupid, etc. I'm sorry but I'm doing my best.
I write and collect everything myself - manual work. So no AI, no automation, etc. 👨🌾
I just wanted to let you know once again.
I appreciate your support and let's check what I found for you today! 🚀

Introducing Swift Testing. Lifecycle
The Swift Testing framework simplifies the creation and organization of tests. By using @Test, you can define test functions. Test suites can be created using structs or classes, allowing for setup and teardown logic.
The @Suite macro enables serial execution of tests.
Understanding actors in Swift
Swift actors offer a powerful solution to prevent data races in concurrent programming. By isolating mutable states and enforcing asynchronous access, actors ensure that only one task can modify shared data at a time.
This article delves into the core concepts of actors, including their definition, interaction with async/await, and the importance of Sendable types.
Using the #require macro for Swift Testing
The Swift Testing framework provides a powerful tool for writing clear and concise tests. The #require macro allows you to set prerequisites for a test to proceed, making your tests more reliable and easier to understand.
By using #require to unwrap optionals, you can write more concise and expressive tests. This enhances the overall quality and maintainability of your Swift code.
