Incompatible with Swift 4.0

[Fonta1n3]

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
