Swift 6 support improvements

[ishanijerin1]

You can now build in Swift 6 language mode, and if you can't jump straight to Swift 6, a new build setting lets you adopt Swift 6 features individually.

I have been talking about the negative aspects of Swift 6, such as the time it takes to adapt to it, but Swift 6's Swift Concurrency feature is a powerful feature for preventing data races and helps create robust projects.

Traditionally, String Catalog was introduced saudi arabia email address as a localization tool for the SwiftUI era, but some features have been enhanced.

The String Catalog filter bar has been enhanced to support more complex search criteria, including Begins with, Does not contain, and more.

The String Catalog editor now displays inline warnings and errors for a variety of issues.

Testing improvements
A new testing framework called Swift Testing has been introduced.

The Test Plan Editor now lets you include or exclude Swift Testing tests and suites by tags.

Also, when you run tests from Xcode, code coverage is automatically displayed in Xcode.
