Improve/use shorthand syntax for unwrapping optionals and fix typos

Improved code with shorthand syntax for unwrapping optionals and fixed a few typos in documentation.

For example:

This code:

if let error = error { ... }

is replaced with

if let error { ... }

Thanks for the PR!

Looks like there are some build errors on Xcode 14 in CI which we plan to support for the next few months as long as the App Store does.

Marking for review and merge for the next major release, when we'll have dropped Xcode 14 support.
