genericExtensions has no effect for me

[stherold]

My config file looks like below (don't wonder I'm in setup mode right now and enable rule by rule). What exactly has to be written in the option generictypes?

#
# Format command: `swiftformat --swiftversion 5 --config "./.config/swiftformat" .`

--generictypes is a list of types that support being extended using a syntax like:

extension Array<Int> { ... }

Instead of

extension Array where Element == Int { ... }

[stherold]

Thx for the hint 👍

But still it SwiftFormat does not correct extension Array where Element == Int { ... } for me.

[nicklockwood]

@stherold it looks like you are setting the --swiftversion option to 5, but this syntax is only available since 5.7, so the rule will be disabled.

[stherold]

Ooops, this would have been a long journey without your hint! thank you very much 🎉

[stherold]

Works, thanks 🎉
