Unfortunately I am very novice at swift so I probably cannot be helpful in terms of PR fixing this one. But some community help would really be appreciated 😄

@bherila thanks for reporting the issue with the spec. We'll look into that ...

@bherila it's due to number used in enum values. I filed #2508 to support number in enum and will merge it on Monday.

Will let you know once it's merged.

@wing328 I am still seeing this exact same error on 2.2.0 even though #2508 seems to indicate that it should be fixed

[wing328]

@bherila @alecgorge fixed via #3535. Please pull the latest master to give it a try.

@wing328 yup, it works great. Thanks so much for the quick turn around.
