Question or issue on macOS:

How To Update El Capitan 10.11.6
Can I Upgrade From El Capitan 10.11.6

I am taking a course on programming with flutter, and it needs Xcode 9 or higher. My mac is currently running 10.11.6 and it can't update any more. I was wondering if there was any way to get Xcode. Xcode For 10.11; Xcode For El Capitan 10.11.3 Download Mac; Mar 21, 2016 Thank you. I gave up after an hour w no visible change. I was upgrading from 10.11.3. I simply turned off the 2 yr old dual 27″ iMac, waited a bit, then restarted.

I’m just updated my Mac to OS X 10.11 El Capitan DP 2, and I disappointed that it does not support Xcode 6.3.2

The latest Xcode running under 10.11.6 would be Xcode 8.2.1. You can download Xcode 8.2.1 on apple developers site. I do not remember which SDKs Xcode 8.2.1 comes. Mar 29, 2017 MacOS 10.11.6 XCode 8.2.1. Find the Download URL. The first thing you have to do is find the file that you need to download. To do this, open up XCode and click on “Preferences Components” to see a list of available simulators to download. Click the down arrow next to the simulator you want to download to begin the normal download process.

Now, how do I work? I have a project to do, and it’s not a good time to convert my project to Swift 2/Xcode 7 since it’s impossible to submitting at this time?

How to solve this problem?

Solution no. 1:

Open terminal and use this command

/Applications/Xcode.app/Contents/MacOS/Xcode </dev/null &>/dev/null &

Solution no. 2:

From the El Capitan release notes:

Xcode versions prior to 7 are not supported on OS X El Capitan Beta 3

And from the Xcode 7 beta 4 release notes:

How To Update El Capitan 10.11.6

Xcode 6.x has known compatibility issues when run on OS X version 10.11 El Capitan. It is strongly encouraged that you use Xcode 7 when running on OS X El Capitan.

I know it doesn’t help you much now, but as a general rule of thumb, I recommend not upgrading anything in your build process if you’re on a deadline and you can’t easily revert.

Hope this helps!

XCode is an integrated development environment developed to work on Mac operating systems. It contains a suite of software development tools developed by apple. XCode facilitates us to develop software for macOS, tvOS, iOS, and watchOS. The latest stable release of XCode is 11.0, which is available on the Mac App Store for all the users of macOS Mojave. In this section of the tutorial, we will go through various contexts of XCode. We will also go through multiple sections of XCode.

Version History

SN	Release year	Operating system	Features
1.x series	2003	MacOS 10.3 +	It is based on the project builder. XCode 1.5 has an improved debugger and better code compiler.
2.X series	2005	MacOS 10.4 +	It included the Quartz Composer, better code sense indexing for Java, and Ant support. The XCode 2.1 could create pre-compiled binary files.
3.X series	2007	macOS 10.5+	The XCode 3.X series includes DTrace debugging tool(instruments), refactoring support, context-sensitive documentation, and Objective C 2.0 with garbage collection.
4.X series	2011	macOS 10.6.8+	XCode version 4 integrated the XCode editing tool and interface builder into one application. Among many changes, it also included the support for iOS iOS 5.1, enhancements to iOS simulator, and suggested the move to LLDB debugger versus the GDB Debugger.
5.X series	2013	macOS 10.8+	It added support for iOS 7 SDK. It also added a version of Clang generating 64-bit ARM code for iOS 7. Apple removed support for building garbage collected Cocoa binaries in XCode 5.1
6.x series	2014	macOS 10.9.4+	XCode version 6 provided many enhancements, including the support for all new programming language of apple i.e., Swift. XCode 6 also includes the support for playgrounds and live debugging tools.
7.x series	2015	macOS 10.10.3+	XCode version 7 provided support for Swift 2 and metal for OS X. It also added the support for deploying an iOS device without having an apple developer license.
8.x series	2016	macOS 10.11.5+	XCode version 8 provided support for Swift 3.
9.x series	2017	macOS 10.12.6+	It provided support for Swift 4 and metal 2 for OS X.
10.x series	2018	macOS 10.13.6+	Xcode 10 introduced support for the Dark Mode announced for macOS Mojave, the collaboration platforms Bitbucket and GitLab (in addition to GitHub), training machine learning models from playgrounds, and the new features in Swift 4.2 and Metal 2.1, as well as improvements to the editor and the project build system.
11.X series	2019	macOS 10.14.4+	XCode 11 introduced support for the new features in Swift 5.1, as well as the new SwiftUI framework (although the interactive UI tools are only available when running under macOS 10.15). It also supports building iPad applications that run under macOS; includes integrated support for the Swift Package Manager; and contains further improvements to the editor, including a 'minimap' that gives an overview of a source code file with quick navigation.

The latest version of XCode i.e., Version 11, can be installed on macOS Mojave from the Apple Mac App store. However, in this tutorial, we are going to use XCode 10.2.1

A Quick walkover of XCode

Let's have a quick walkover of XCode 10.2.1 and understand how the development in XCode is going to be done.

When we create a new XCode Project, the following window is shown which provides the target information of the XCode Project. It shows every information of the project that includes Bundle Identifier, App version, Build Version, Signing Information, Deployment Information, Linked Binaries and framework information, and application launch icons.

Above the target information, there is a pane of project information which shows all the information about the project given in the following image. It contains information about the iOS version for which the application is created. It also contains release information.

We will discuss the target and project information later in this tutorial in detail.

Now let's look at all the components of an XCode window (below image) in detail.

Standard Editor

Can I Upgrade From El Capitan 10.11.6

The standard editor is shown in the middle of the window. As the name suggests, it is the standard editor of the project in which the project files are edited. It contains the information about the file commented at the top and the initial View Controller class file with the lifecycle method created. (The lifecycle methods will be discussed later in this tutorial. At the topmost pane of the Standard editor, the hierarchical information about the project file is shown. It can also be used to open other files in the same editor. However, we can also navigate to other project files using the project navigator also.

Assistant Editor

The Assistant Editor is mainly used to create outlets of the storyboard components (Textfield, Label, etc.) in the corresponding View Controller class file. However, the Assistant editor facilitates us to look at two files in the editor simultaneously.

Project Navigator

The project navigator is shown at the left of the window. It shows the file structure of the project. It is used to navigate through the project. Initially, an XCode project contains the files shown in the following image.

File Inspector

The inspectors are shown in the right of the XCode window, as shown in the below image. The file inspector shows the full information about the corresponding swift file opened in the standard editor. It contains the Name, Type, Location, and the interface builder document-related information.

Quick help inspector

It is used to provide help to the user where it can search the documentation about the syntax. It is shown as the below image.

Identity Inspector
