This plugin is provided as-is with no guarantees of any kind.
Syntax highlighting is from original xclangspec created by Raphael Bartolome: https://github.com/rbartolome/xcode-cappuccino It is a work-in-progress - a copy of the Objective-C xclangspec is included from Xcode 12.3 for reference (but not installed). Xcode has adopted the Language Server Protocol for C, C++ and Objective-C, but does not yet use it for syntax highlighting. Development of an Objective-J LSP server would allow implementation of code-completion, refactoring and other beneficial features.
Plugin and installer guided by: https://github.com/youknowone/rust-xcode-langspec https://github.com/steventroughtonsmith/lua-xclangspec https://github.com/BrainiumLLC/rust-xcode-plugin https://github.com/touchlab/xcode-kotlin
From Xcode 8 onwards, Xcode plugins must be code-signed by Apple, with the exception of those for language syntax colouring. Even those must conform to a plugin registration scheme, which must also include the app UUID for supported versions of Xcode.
If Xcode UUID is not listed here, please create an issue (or preferably a pull request!).
The UUID for the requested UUID must be provided when creating an issue and can be found with this command:
$ defaults read /Applications/Xcode.app/Contents/Info DVTPlugInCompatibilityUUIDThe UUID can also be immediately added to the above-referenced Info.plist.
Once added, execute the setup.sh script using sudo.
Xcode must be restarted if already loaded.
