Here is my code:
PDKClient.sharedInstance().createPinWithImage(image, link: NSURL(string:"http://domain"), onBoard: "MyBoard", description: caption, progress: {percent in
print(percent)
}, withSuccess: {PDKResponseObject in
print("ok")
print(PDKResponseObject.boards())
}, andFailure: {error in
print(error)
})

Error 401 means one of the following.
1.Authentication failed.
2.Authorization failed.
3.You are not permitted to access that resource.
Double check your permissions, check your session token expired or not.
So I think that there is nothing wrong with your code, or the request. It's something with the permissions you have in your Pinterest app.
Try changing the request URL from http to https.
Check the parameters you sending to Pinterest, check whether the parameter names are correct or not, as specified in Pinterest documentation. Also those parameters has the proper type of data, I mean do not pass String in the place of Integer value.
