 Here are recommended best practices for developing for iOS:
 
 * The iOS file system is case-sensitive. Ensure that the case is correct for file names like `IntuneMAMResources.bundle`.
+* Registering custom URL schemes allows specific URLs to redirect into your app. iOS and iPadOS allow multiple apps to register the same custom URL scheme and the OS determines which application is invoked. Please refer to the Apple documentation [Defining a custom URL scheme for your app](https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app) for recommendations to help avoid custom URL scheme collisions and security guidelines for handling malformed URLs.
