The last part of iOS app development is distribution: getting your app tested, submitted to the App Store, and in the hands of users. Todd Perkins walks you through the entire process: preparing your app's visual assets, such as icons and launch screens; conducting user testing with TestFlight (a tool exclusive to the Apple Developer Program); and submitting the app to Apple for approval via iTunes Connect. Once you've finished this course, the last part of our iOS 10 App Development Essentials series, you should have the fundamental skills to start programming new iOS 10 apps with Xcode, Swift, and the iOS SDK.
