Xcode extension to change the access control level of Swift code selection

This project was inspired by (AccessControlKitty)[https://github.com/zoejessica/AccessControlKitty].

Due to AccessControlKitty being outdated and no longer maintained by the author, and Swift being a constantly evolving language, the original version used regex matching to parse code, which leads to a large number of syntax recognition errors in the latest version of Swift.

AccessControlNinja uses swift-syntax to parse Swift code, ensuring it can understand every line of Swift code.

AccessControlNinja also supports package access control level and import statements.

• Works on selected Swift code to switch between public, private, fileprivate, internal, open, package or no access control modifier. Choose an option from the new Access Level of Selection item at the bottom of Xcode's Editor menu:

• Increment access levels in selected code. So, fileprivate code becomes internal, internal becomes public.

• Decrement access levels. private code stays as is, fileprivate become private, and public code becomes internal.

• Set all appropriate access modifiers to one level

• Remove access notation entirely

Since swift-syntax only parses Swift syntax and does not understand the code, it will not determine whether this access control can be applied in the current context.
