如何在swift 3中生成OAuth1 HMAC SHA1签名

Question

I'm working on a small swift program to work with Yelp API over OAuth-1. I am looking to generate a HMAC-SHA1 signature.

I have the customer key, secret key , token and token secret.

From what I know, to make an API request with OAuth1 , we need the following attributes :

1. 1.oauth_consumer_key
2. oauth_token
3. oauth_signature_method = (HMAC-SHA1)
4. oauth_signature
5. oauth_timestamp
6. oauth_nonce

I have the first 1,2,3 parts but I don't know how do I generate #4,5,6 I am kind of new to ios/swift3 so please point me into right direction
