For Lazarus (an IDE with visual components similar to Delphi) I switched to code-first components and did away with the form files. You can probably do this with all of these frameworks.
We’re building an AI agent for Delphi — and a major part is it supporting visual form editing. It works. You can see the form change live in the designer as the AI does its stuff.
Right, good that you've got that going, congratulations to you and your team. Design time does make human development much easier, since you are able to see the working prototype run as you design it, not sure what the point is if AI is doing that, since the value is in making the development cycle shorter, which the AI has no use for.
