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

Download from the Mac App Store – versions have now diverged – this repo contains the latest fixes

• Works on selected Swift code to switch between public, private, fileprivate, internal 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, private and fileprivate code becomes internal, internal becomes public, and any public code stays as is.
• Decrement access levels. private code stays as is, fileprivate and internal become private, and public code becomes internal.
• Create API – changes all internal code to public, exposing it as API for your framework
• Remove API – similarly, changes all public code to be internal, removing its visibility as API
• Set all appropriate access modifiers to one level
• Remove access notation entirely
• Setters with overriden access levels (for example, private(set) internal var) are treated separately: when incrementing/decrementing access, or making/removing API, overridden setters maintain their current access level. If the underlying entity ends up with the same access level as the overriden setter, the explicit override is removed. When setting code to a single access level, the explicit setter override is removed so the entire entity is set to the desired level.

• It’s not particularly smart, so for example it doesn’t know if a function can’t be made public because it relies on an internal type. Or if a subclass can't be made public because its superclass isn't public. And it certainly can't reason about anything going on in any other file. It just operates on the bits of selected Swift code that could, grammatically speaking, have an access control modifier.
• It also doesn’t support open or final for the moment, mostly because it’s a bit more work and just ship it already, and partly because I sort of feel those notations should require a bit more forethought when planning a framework.
• Next on the list are the (new I think) warnings in Swift 5 about redundant public declarations of top level members in public extensions. Work in progress, to come shortly 😅

Available to download now on the Mac App Store – versions have now diverged – this repo contains the latest fixes

The MAS and github versions are currently in sync woohoo! But if you want to install yourself:

• Download the Xcode project
• Archive the Mac app target
• From the Organizer window, which should open automatically, click Distribute and export the created archive using the option Copy to use locally. Save wherever you like.
• Launch the app
• The extension will now be available in System Preferences, under the Extensions pane, listed as an Xcode Source Editor extension. Activate!
• After an Xcode restart, find it under the Editor menu - it only works on selected Swift code
• For even more radness, you can bind keyboard shortcuts to the menu commands

• Please create an issue or tweet @zoejessica.
