AI BriefingSwift REPL
Key point
Replit has released a beta version of a Swift REPL that maintains state and allows interaction, going beyond the existing simple execution approach.
Details
Existing web-based Swift implementations have been limited to editor-style formats where you simply write code and press a run button, failing to provide an environment that maintains state and allows interaction.
Replit, inspired by DrScheme (now DrRacket), has released a beta version of a Swift REPL that lets you interact directly with the resulting environment in the console after running code.
When a user writes and runs code in the editor, the interpreter executes the code, and based on the environment created afterward, the user can perform the following in the console:
- Call defined functions
- Change and manipulate variable values
- Freely interact within the running environment
Since a new environment is loaded every time you run the code, users can always test and experiment starting from a clean state.
