When you create a new project in Xcode 11, you automatically get the new SceneDelegate for free. This is great if you want to build an app that's for iOS 13 and newer but as soon as you change your deployment target to an iOS version that's lower than iOS 13, your app will have trouble compiling. Xcode 11 brings lots of new features such as support for Swift 5.1, Apple’s latest iteration of the Swift programming language, SDKs for iOS 13, tvOS 13, watchOS 6 and macOS Catalina 10.15. Xcode 11 welcome screen. Xcode is an integrated development environment (IDE) that allows users to create and test iPhone, iPad, Mac and Apple Watch apps using OSX and iOS. Xcode supports a variety of programming languages such as Swift language, C, C, AppleScript, and etc. Xcode 11.3.1 comes with: Transporter App; Command Line Tools for Xcode 11.3; iOS Simulator SDKs. Xcode 12.2 beta includes support for iOS 14.2, tvOS 14.2, and more The latest Xcode beta for macOS Big Sur includes support for unreleased operating systems likely to be used in the upcoming.
Xcode is a complete developer toolset for creating apps for Mac, iPhone, iPad, Apple Watch, and Apple TV. Xcode brings user interface design, coding, testing, debugging, and submitting to the App Store all into a unified workflow.

Submitting apps to the App Store using Xcode
If you’re an Apple Developer Program member, Xcode provides an integrated workflow to prepare and submit apps to App Store. You should use the latest version of Xcode available on the Mac App Store to submit your apps, or when available, the latest GM seed release from the Downloads page.
Do not submit apps built using beta software, as beta versions of Xcode, Operating Systems, and SDKs are for development and testing only.

Providing feedback and reporting bugs
Your feedback goes a long way towards making Xcode even better. With Feedback Assistant, you can report issues or request enhancements to APIs and tools. Include detailed information about issues, including the system and developer tools version information, and any relevant crash logs or console messages. To ask questions and find answers by Apple engineers and other developers, visit the Apple Developer Forums.
Invalid private key and certificate pairing
If you received an error message saying, 'Xcode could not find a valid private-key/certificate pair for this profile in your keychain.' This error message indicates that the Keychain Access application on your Mac is missing either the public or private key for the certificate you are using to sign your app.
This often happens when you are trying to sign and build your app from a different Mac than the one you originally used to request your code signing certificate. It can also happen if your certificate has expired or has been revoked. Ensure that your app’s provisioning profile contains a valid code signing certificate, and that the Keychain Access application on your Mac contains that certificate, the private key originally used to generate that certificate, and the WWDR Intermediate Certificate.
For instructions on how to resolve this and other code signing errors, review the Code Signing Support page.
