Installing Xcode

Before we install Visual Studio, we need to download and install Xcode. Xcode is the official development IDE from Apple and contains all the tools they provide for iOS development, including SDKs for iOS, macOS, tvOS, and watchOS. 

We can download Xcode from the Apple developer portal (https://developer.apple.com) or from Apple App Store. I recommend that you download it from App Store because this will always provide you with the latest stable version. The only reason to download Xcode from the developer portal is if we want to use a prerelease version of Xcode, to develop for a prerelease of iOS, for example.

After the first installation, and after each update of Xcode, it is important to open it. Xcode often needs to install additional components after an installation or an update. You also need to open Xcode to accept the license agreement with Apple.
