Availability of Currency transfer in objective c

[Pavan96]

Hello, Thanks for good library.
I have integrated this library into the objective c project. But due to complier limitations it not able to convert the some swift files to objective c compatible. The possible workaround for this one will be as follows -
1. Inherit the Currency class from NSObject
2. Convert the PrivateKey and PublicKey structs to class, so that complier can create respective objective c files in bridging header
If you have any other solution will be appreciated.
