eth address error

Hello, I used your framework to generate the btc address is correct, eth address is wrong, is there any good solution?

Cant find openssl files

Cant run the project because xcode cant find open ssl files

Incompatible with Swift 4.0

When i run "carthage update --platform ios" I get:

*** Skipped installing CryptoSwift.framework binary due to the error:
"Incompatible Swift version - framework was built with 4.1 (swiftlang-902.0.48 clang-902.0.37.1) and the local version is 4.0.2 (swiftlang-900.0.69.2 clang-900.0.38).

I really don't want to have to download an update of Xcode to be able to use this library. Any chance you can specify the CryptoSwift version to 0.7.0 so that Swift 4.0 works? Or are there any other options for me other then updating Xcode?

Thanks

Problems in derivation with testnet

Hi, I believe that there is a problem in derivation and some time doesn't work well. I made some tests with testnet and validate results with https://iancoleman.io/bip39/ and it doesn't match.

I found that in the file internal.m (line 130) you save new private key like this

        result = [NSMutableData dataWithLength:numBytes];
        BN_bn2bin(privateKey, result.mutableBytes);

and I believe that you need to save new private key like this

        result = [NSMutableData dataWithLength:32];
        BN_bn2bin(privateKey, &result.mutableBytes[32-numBytes]);

Regards
