Utility for creating version 3 UUID from name

gistfile1.txt

    func nameUUIDFromBytes(name: String) -> NSUUID{
        let nameBytes = name.data(using: .utf8)
        var digest : Data = (nameBytes?.md5())!
        digest[6] &= 0x0F
        digest[6] |= 0x30
        digest[8] &= 0x3F
        digest[8] |= 0x80
        
        var arr : [UInt8] = []
        for i in digest {
            arr.append(i)
        }
        return NSUUID(uuidBytes: arr)
    }

I should note you need CryptoSwift for this to work https://github.com/krzyzanowskim/CryptoSwift
