@yura Unfortunately, this not what expected to be done here.

You cannot just change expected result, because it's coming from canonical-data json file which is shared across all exercism tracks.

Moreover, you cannot just chage *Tests.swift file, because all of them are generated from template.swift. And even if you try to modify the template you would find out that there is no test data at all. It's all got from canonical-data repo.

So, what is needed to be done here is to modify closures for foldl in template (and verify other functions) to work as it is expected in canonical-data. And it's expects { element / accumulator }. And then you need also to fix .meta/*Example.swift solution for CI tests to pass.

Feel free to ask any questions!
