Is it possible to copy text to clipboard on ios?
Programmatically in App Inventor, there is not. One question would be what might the design of this look like from a cross platform perspective. For example, should interacting with the clipboard be a separate component, or do we attach the behavior to an existing component like the Sharing component or Screen?
It'd not make sense to clutter the Screen component, there are probably tens of small things like these.
If it's just for a single CopyToClipboard block, it'd make sense to add it to the Sharing component.
But sometimes the features extends a little deeper (e.g. pasting from clipboard), so it's probably good to keep it modular incase we'd have to extend to some more features...
Over time, I'm pretty sure we'd need a lot more newer component definitions, there are tens of these small things like clipboard that would need to be supported for the iOS ecosystem by default, if to compensate for absence of extensions...
