🍎(in-progress) XCode LSP with Emacs

A random collection of stuff before I actually write a real guide

• Use xcodebuild to list schemes

• Use xcode-build-server config to configure a buildServer.json

• The lsp-sourcekit package will be able to handle all languages from then on

• REQUIRES a build from XCode (very annoying): Product > Build For > Running

  • Based on the source codes (https://github.com/SolaWing/xcode-build-server/blob/master/server.py and https://github.com/apple/sourcekit-lsp/blob/main/Sources/SKCore/BuildServerBuildSystem.swift#L181), there are three important things that need to exist:

    • indexDatabasePath: Typically in `~/Library/Caches/xcode-build-server/-Users-name-path-to-project/indexDatabasePath-*`

    • indexStorePath: Typically in ~/Library/Developer/Xcode/DerivedData/ProjectName-hashlike/Index.noindex/DataStore

    • compile_file: Typically called ~/Library/Caches/xcode-build-server/-Users-name-path-to-project/compile_file-ProjectName-md5Hash

• For god knows what reason, when you do xcodebuild -workspace ... -scheme ..., you only get indexDatabasePath and indexStorePath. compile_file can only be generated by xcode (the app)

  • There's probably a root cause for this, but I can't be bothered

• So, for a project to be successfully, fully indexed, you need to build at least once in xcode (the app). This is a problem if you're trying to bypass signing with CODE_SIGN_IDENTITY="" CODE_SIGNING_REQUIRED=NO CODE_SIGN_ENTITLEMENTS="" CODE_SIGNING_ALLOWED=""

TODO: Put the other commands here
