How to authenticate Trello API user with read, write permissions using OAuth1Swift - ios

Question

I am trying to authenticate a user getting read, write access permission to Trello API. I am using OAuth1Swift for authetication but cannot add paramaters to add a permission and app name.
How do we add these paramateers? This is my code below.
OAuthSwift Library
Trello API Docs
func doOAuthTrello() {
let oauthswift = OAuth1Swift(
consumerKey: "consumerKey",
consumerSecret: "consumerSecret",
requestTokenUrl: "https://trello.com/1/OAuthGetRequestToken",
authorizeUrl: "https://trello.com/1/OAuthAuthorizeToken",
accessTokenUrl: "https://trello.com/1/OAuthGetAccessToken"
)
self.oauthswift = oauthswift
oauthswift.authorizeURLHandler = getURLHandler()
let _ = oauthswift.authorize(
withCallbackURL: URL(string: "oauth-swift://oauth-callback/trello")!,
success: { credential, response, parameters in
self.showTokenAlert(name: serviceParameters["name"], credential: credential)
self.testTrello(oauthswift)
},
failure: { error in
print(error.localizedDescription, terminator: "")
}
)
}

Answer 1

After trying everything, this is the solution:
lazy var paramaters:[String: String] = {
return [
"consumerKey": "consumerKey",
"consumerSecret": "consumerSecret",
"requestTokenUrl": "https://trello.com/1/OAuthGetRequestToken?scope=read,write,account&expiration=never&name=AppName",
"authorizeUrl": "https://trello.com/1/OAuthAuthorizeToken?scope=read,write,account&expiration=never&name=AppName",
"accessTokenUrl": "https://trello.com/1/OAuthGetAccessToken?scope=read,write,account&expiration=never&name=AppName"
]
}()
The magic happens by adding ?scope=read,write,account&expiration=never&name=AppName to the url parameters
