Does not encode NSTag with tag 0

Problem with big integers

Hello, I'm implementing encode/decode and noticed a problem with both of them when using big numbers. I'm using the following set of data.

let barr = [**1531842146400**,[1332, 0, "0.3.0-dev", "0.3.0-dev", "4.0.2", "866191031649643", "8935101811542082547", "M95FAR02A08","AXN_2.32_3337_15010801", 3, 0],[1398, 8, NSSimpleValue(nil), NSSimpleValue(nil), NSSimpleValue(nil), NSSimpleValue(nil), NSSimpleValue(nil)],[1376, 7, 1]] as [Any]

 let cc = CBOR.encode(barr as NSArray)

which encoded using the playground results in 9f1b00000164a8e830608b1905340069302e332e302d64657669302e332e302d64657665342e302e326f38363631393130333136343936343373383933353130313831313534323038323534376b4d393546415230324130387641584e5f322e33325f333333375f313530313038303103008719057608f6f6f6f6f6831905600701ff

My problem is that the first value 1531842146400 since it's a bit integer can't be encoded (crashes) and when decoding it returns an empty array not showing any values. But if I use a smaller number everything works fine. What can I do to work around this situation?

Thanks

Problem with ut8 strings with non-english characters

The code crashes

Request: Support for binary UUID / NSUUID

It would be awesome if you added support for UUIDs as per https://github.com/lucas-clemente/cbor-specs/blob/master/uuid.md

I'm willing to code support myself, tried using the custom tag support as well but couldn't. Please help, thanks!

I'm able to get a UUID's representation as [UInt8] but I can't figure out what to do next after that.

Problem with NSData as Value when Decoding

I have this sample use case where I have a JSON-like NSDictionary but I want to put some random NSData to prove that I can add something like a small UIImage/Audio file into CBOR.

func test_2_encodeMap_2() {

        // begin generating some random NSData
        let length = 2048
        let bytes = [UInt32](repeating: 0, count: length).map { _ in arc4random() }
        let data = Data(bytes: bytes, count: length)
        // end generating some random NSData
        
        let json: NSDictionary = [
            "_id": "123abc",
            "color": "Red",
            "age": 56,
            "mileage": 56.444,
            "tags": [
                "a", "b", "d", 4
            ],
            "data": data
        ]
        
        
        var encoded = CBOR.encode(json as NSDictionary)
        var decoded = CBOR.decode(encoded!) as! NSDictionary
}

It encodes fine but crashes saying "Thread 1: Fatal error: Array index is out of range" at Decoder.swift on Line 77

What am I doing wrong?

This library is full of bugs, use https://github.com/myfreeweb/SwiftCBOR

It has caused a lot of frustration

Supporting Unicode languages

CBOR Swift does not support Unicode languages and to solve this problem you should implement as follows:

In "Extensions" :

public var ascii_bytes: [UInt8] {
        // To supporting unicode languages it should return with .utf8 encoding
        return self.data(using: .ascii)?.bytes ?? self.data(using: .utf8)!.bytes
    }

In "Encoder":

@objc override func encode() -> String {
        
        // To support Unicode languages, the string encoding must be specified before giving the string length
        let asciiBytes = self.ascii_bytes
        let encodedArray = Encoder.prepareByteArray(major: .major3, measure: asciiBytes.count)
        let headerData  = Data(bytes: encodedArray).binary_decimal.hex
        let strData     = Data(bytes: asciiBytes).hexString
        
        return headerData.appending(strData)
    }
