I will include links to the articles as they are published. 6 | 7 | ## Setup 8 | 9 | To run the application, you will have to perform the following steps: installing the AWS dependencies, setting up the user pool configuration, and creating a sample user. 10 | 11 | ### Installing Dependencies 12 | 13 | This application utilizes [CocoaPods](https://cocoapods.org/) for managing the dependencies. At this point, the only dependencies are the specific pieces of the AWS iOS SDK which relate to Cognito User Pools. 14 | 15 | If you haven't used CocoaPods, be sure to read the [Getting Started Guide](https://guides.cocoapods.org/using/getting-started.html). Once you have CocoaPods installed, just navigate to the project directory in your terminal (the one which contains the Podfile file) and enter the following: 16 | 17 | ```bash 18 | pod install 19 | ``` 20 | 21 | This will install the needed dependencies for this project. 22 | 23 | ### User Pool Configuration 24 | 25 | To use this example application, you will need to create a Cognito User Pool and add in four specific values to a config file. The config file should be named `CognitoApplication/CognitoConfig.plist`. This file should have the following keys: 26 | 27 | | Key | Type | Value | 28 | |----|----|----| 29 | | **region** | String| This is the region in which you created your user pool. This needs to be the standard region identifier such as 'us-east-1' or 'ap-southeast-1' | 30 | | **poolId** | String | The id of the user pool that you created | 31 | | **clientId** | String | The clientId configured as a part of the app that you attached to the user pool | 32 | | **clientSecret** | String | The clientSecret that is configured as a part of the app that you attached to the user pool | 33 | 34 | ### Creating a Sample User 35 | 36 | This initial version of the application does not include user signup (that will be handled in the second article). This requires that you setup a user in the Cognito console. For this to work as expected, the `given_name`, `family_name`, and `email` should be the only required attributes. 37 | -------------------------------------------------------------------------------- /CognitoApplication/VerificationViewController.swift: -------------------------------------------------------------------------------- 1 | // 2 | // VerificationViewController.swift 3 | // 4 | // Copyright (c) 2017 David Tucker 5 | // 6 | // Permission is hereby granted, free of charge, to any person obtaining a copy 7 | // of this software and associated documentation files (the "Software"), to deal 8 | // in the Software without restriction, including without limitation the rights 9 | // to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 10 | // copies of the Software, and to permit persons to whom the Software is 11 | // furnished to do so, subject to the following conditions: 12 | // 13 | // The above copyright notice and this permission notice shall be included in all 14 | // copies or substantial portions of the Software. 15 | // 16 | // THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 17 | // IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 18 | // FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
