There is no one best way. Different people have different expectations, requirements, experiences.

If you are just starting to learn about app development, maybe start with the language document, and with a Swift Hello World program, or similar.

Also start with Playgrounds and its Swift tutorials, and not Xcode: Swift Playgrounds - Apple Developer

Playgrounds are intentionally simpler than Xcode. But Playgrounds are very capable, and very useful. Why Playgrounds first? Learning both Swift and Xcode at the same time is a much larger effort, and learning Swift first will get you productive more quickly. (I use both Xcode and Playgrounds. Xcode itself is way more complex than is Playgrounds.)

As for learning more about the Swift language and syntax (in addition to the tutorials online), here is a (free) Apple book:

If you’re just starting out with programming more generally:

Learn, Build, and Innovate - Apple Developer

Here are a Stanford iOS Swift course and an intro-to-programming Harvard Python course (both are college level courses, and free):

For a wider introduction, and wider options, beyond Swift:

The current Xcode for macOS.
