v1.2.0 violates semantic versioning

[allewun]

The latest SipHash, 1.2.0, requires Swift 4.

The last version of BigInt to support Swift 3, v2.1.2, depended on SipHash ~> 1.1. This means that SipHash 1.2.0 is now being used by CocoaPods, which is incompatible and results in failed compilation.

Seems like v2.0.0 would've been a better version to use for this breaking change.

For those that are having the same issue with BigInt, just add SipHash explicitly to your Podfile. You can just specify pod 'SipHash', '1.1.2' to pin that version and prevent CocoaPods from implicitly choosing a higher version.

This violation was already made and we can't revert it as this would break even more projects. Also as of now most people are using Swift 4 and upwards anyways so it doesn't really matter. I'm closing this issue due to inactivity. If you have any other problems just open a new one.
