We're already starting new projects on PHP 7.4 with strict typing and typed properties.
It would be nice if at some point in the near future Skipper would be able to export typed properties for "annotation" mode if configured to do so.
It's definitely on our todo list.
The current state where Skipper can read such definitions but not write is an only a temporary solution (https://support.skipper18.com/402/downloads-skipper-beta).
Unfortunately, it will be a huge job because currently all parsers/exporters are able to modify only @orm annotations. Now it will be necessary to update also non-annotations parts and modify code directly.
Welcome to the Skipper support forum. This support forum covers both Skipper and its older version, ORM Designer issues.
Feel free to ask us anything about Skipper or ORM Designer. If you find any problem or glitch, or if you have an idea for an enhancement, please let us know.
