plaid-swift

Swift wrapper for the Plaid API. See Plaid docs for more info.

##Quick start #####1) Copy the Plaid.swift file into you project:

#####2) In your AppDelegate.swift file, initialize plaid-swift with your client_id and secret:

See BaseURL section below for more info

Plaid.initializePlaid(clientId: "Your client_id", secret: "Your secret", appStatus: .Testing or .Production)

#####3) Use plaid-swift functions (They all begin with "PS_")

See Functions

####MFA functionality working, check back for updated documentation
