Evaluating code during debugging

[shoplab7]

When I stop on breakpoint, how do I evaluate expressions(similar to p/po/etc in xcode)?
Also, how do I fix this issue?

Exception: Could not find type system for language swift: TypeSystem for language swift doesn't exist

In dap-ui go to repl buffer and hit a :). I’m not sure what’s the second issue. Maybe try a clean build from Xcode

Thanks 😅
Regarding second issue: it seems like some issue with codelldb and it isn't going away after clean build.
Whenever I try to evaluate any expression(even p 1), I'm hit with

[debug-adapter stderr] [ERROR codelldb::debug_session] error: Could not find type system for language swift: TypeSystem for language swift doesn't exist
error: Could not find type system for language swift: TypeSystem for language swift doesn't exist

Was I supposed to do anything besides downloading .vsix for my os(MacOS with M1 -> codelldb-darwin-arm64), unpacking it and updating codelldbPath in config?(Also, I tried printing the resulting path and it is correct)

Hmm, it should be enough, you can check also:
https://github.com/wojciech-kulik/xcodebuild.nvim/wiki/Integrations#-debugger

Alternatively, try switching to the sample config and see if the issue still occurs: https://github.com/wojciech-kulik/xcodebuild.nvim/wiki/Neovim-Configuration#%EF%B8%8Fsample-config-for-ios

or maybe something is wrong with the latest codelldb release?

I had mason and it seems like it was overriding whatever xcodebuild did to dap.
I removed mason, now I'm getting

HOME/tools/codelldb-darwin-arm64/extension/adapter/codelldb exited with code 101
Couldn't connect to 127.0.0.1:13000: ECONNREFUSED

Also, when I accidentally opened HOME/tools/codelldb-darwin-arm64/extension/adapter/codelldb it got blocked by macos security, so I allowed it and some subsequent .py script

[shoplab7]

Tried dap/dapui configs from starter kit and codelldb 1.10.0, still getting

HOME/tools/codelldb-aarch64-darwin/extension/adapter/codelldb exited with code 101
Couldn't connect to 127.0.0.1:13000: ECONNREFUSED

I tried starting it in terminal myself with

Path/codelldb --port 13000

nvim was able to connect to it, but when I tried to evaluate an expression, I got

[ERROR codelldb::debug_session] error: Could not find type system for language swift: TypeSystem for language swift doesn't exist

Found the issue - I'm using xcodes, so my path to xcode is /Application/Xcode-16.1.0.app/ instead of /Applications/Xcode.app
After I tried changing it in

xcodebuild.nvim/lua/xcodebuild/integrations/dap.lua

Line 416 in 157197d

lldbPath or "/Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework/Versions/A/LLDB",

, everything started working fine. So, I reverted it and created symlink for xcode.

You might also use xcode-select --print-path to determine the path to Xcode before using /Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework/Versions/A/LLDB as the path to LLDB.
