Description:

I'm trying to encode the OAuthSwiftCredential that I get when successfully authenticated so that I can store it in UserDefaults, then decode it to use for future sessions. (If this isn't the right way to avoid having to re-authenticate every time I run my app, please let me know!) I've tried using JSONEncoder and NSKeyedArchiver; however, the former doesn't work because there hasn't been an OAuthSwift release with the Codable version of that file, nor can I use the NSKeyedArchiver, because it dies with the following error:

Could not cast value of type '_NSZeroData' (0x10c079bf8) to 'NSMutableData' (0x10d0820e0).
2018-04-15 21:50:43.124514-0400 xctest[36373:2534923] Could not cast value of type '_NSZeroData' (0x10c079bf8) to 'NSMutableData' (0x10d0820e0).

Ideally, you would issue a new OAuthSwift version that includes the Codable credential, or figure out why the NSKeyedArchiver version doesn't work.

there is Decoder/Encoder implementation

I do not test it myself, someone else implement it
I do not know if there is unit test about it

Yes, there is a Decoder/Encoder implementation, but it's not included in any released version of the code.

Hey! master branch is working well with the Codable implementation. I'm also waiting for a release on CocoaPods. Thanks!
