For Catalina + Xcode 12 + iOS14 SDK no options for now to build Qt Application it's not supported by Qt 5.15.1. Awaiting announced Qt 6.0 that is going to be supported XCode 12 + iOS14 SDK. For Qt will be working only XCode 11 downloaded manually (do not install from AppStore). Dash, Xcode 11 and macOS Catalina. In case you like living on the edge, Dash 4 seems to work great with the macOS Catalina beta. The Apple API Reference docset was updated to work with the latest docs from the Xcode 11 beta. To use the Xcode 11 beta docs, make sure xcode-select -p (in Terminal) points to the location where you.

Xcode is the tool developers use to build apps for the Apple ecosystem – MacOS, iOS, and all things Apple.

This guide will walk you through how to successfully install Xcode onto your Mac, from start to finish.

Download Xcode for macOS 11.0 or later and enjoy it on your Mac. ‎Xcode includes everything developers need to create great applications for Mac, iPhone, iPad, Apple TV, and Apple Watch. Xcode provides developers a unified workflow for user interface design, coding, testing, and debugging.

Here are some handy tips to know before you get started:

Xcode only runs on a mac. If you are on a PC, sadly you won't be able to use Xcode.
You'll need a good, stable internet connection. The latest version is around 8 gigabytes in size.
Be sure to have at least 30 gigabytes of free space on your computer. The latest .xip file (v11.4.1 at the time of writing) is ~8 gigabytes zipped. When you unzip it, that's another 17 gigabytes. Then you'll need the command line tool, which is yet another 1.5 gigabytes.

Here's an overview of the steps to install Xcode

Download Xcode
Install the command line tool
Open the new version
Delete files

Note that I have listed some Terminal commands in the steps below. These commands can be typed into your present working directory. This means that you don't need to navigate to any particular folder.

If you really want to, you can first type cd before typing the commands in the below steps. This will return you back to the home folder.

Step #1: Download Xcode

There are two ways to do this. For the latest version and a theoretically 'easy' installation, you can use the App Store. I don't recommend this option.

I prefer to use the developer site. This comes with the bonus option of being able to download any version you'd like.

Option #1: Download via the App Store for the latest version (not my preferred option)

In theory, this should be a seamless and pain-free process. But if the installation fails for any reason on the last step, it is very hard to troubleshoot.

There are a few reasons for failure, and no easy way to know which is the underlying cause. If you do encounter a failure, you will need to re-download the entire file again each time you try to fix the failure. As the latest version is 8 gigabytes, I didn't much enjoy this approach.

But if you're feeling brave, here are the steps:

Open the App Store on your mac
Sign in
Search for Xcode
Click install or update

Option 2: Download via the Developer site for a specific version (my preferred option)

Head to the 'more' section of the Apple developer website
Sign in with your iTunes account id
Type in the version that you'd like, and download the Xcode_x_x_x.xip file. Keep in mind that Xcode 11.4.1 is 8 gigabytes, so this will take awhile depending on your internet connection.
Once the file is downloaded, click on .xip to extract it. Your laptop will extract it to the same folder you downloaded it to. This extraction process is automatic. You don't need to do anything more after you click on the .xip file. This step will take a few minutes.
[Optional] Once extracted, rename the application to “Xcode11.x.x” if you are using multiple versions.
Drag application to the Applications folder
[Optional] Set the new Xcode version as the default. Open Terminal and type sudo xcode-select -switch /Applications/Xcodex.x.x.app . Replace x.x.x with the version number. For example: Xcode11.4.1.app. You will need to enter in your computer admin password. I'm pretty sure this will update the default Xcode version for all users on your computer, so best to check with other users first

Step #2: Install the command line tool (CLT)

If you have multiple users on your computer, you will need to update the CLT for each user.

Download .dmg

To update the CLT, go to app developer website and download the command line tool .dmg.

If you have never installed Xcode before, you may be able to update with your Terminal by typing in xcode-select --install instead of visiting the developer website.

But if you have an existing version of Xcode installed on your machine, you'll probably see this error:

Install Xcode 11 On Catalina

This means you'll need to go to the developer website instead.

Installing the CLT

When the .dmg has finished downloaded, double click the file to open it. This will open a little window that looks like this:

Double click the box and follow the prompts to install the CLT. It will take a few minutes to complete.

It may ask you at the end of the installation whether you want to move this to the trash bin. When it does this, it's talking about moving the .dmg file to the trash bin. Since you should no longer need this file. I always say yes to this.

Step #3: Open Xcode

Open the Applications folder and open the new version of Xcode. If you renamed Xcode, make sure you open the correct application

Xcode may prompt you to install additional components. Click install. This will take a few minutes.

While it's installing, check that your default Xcode version is the one you just downloaded:

Open Terminal
Type brew config
You should see “CLT” and “Xcode” versions, as well as everything else. This should reflect the version that you have just downloaded. In my case, I downloaded Xcode 11.4.1.

Once the components are installed, Xcode will launch. You should be able to pick up your old projects and continue where you left off seamlessly*.

*Note that if you use any proxy tools, such as Charles, you will need to re-install those certificates in your simulator again.

If you encounter any errors while trying to build or run a project, check which device you are trying to launch. The new version may not remember the device you were using before. If so, click on the device and choose 'Add additional simulators' from the drop down menu to add the device you want.

Step #4. Delete the files

If you don't need the older versions of Xcode on your computer, you can uninstall them and get some hard drive space back.

You can also delete the .xip file of the version you just downloaded, as well as the CLT.dmg file.

That's everything. I hope this has helped you successfully install Xcode. Have fun with it!

Update: I always appreciate the traffic, but the folks at MacPorts have their official installer for Catalina available now. You should use it:
https://www.macports.org/install.php
Updated on 2019/10/09 to work with the public release of Catalina.

Another year, another round of “Oh, shit! My software doesn’t run on the latest version of MacOS!” While MacOS steadily marches towards being a consumer friendly OS that alienates the hardcore users, we continue to try to beat back the tide with tools like MacPorts. I’ll be curious to see how things go with future versions of MacOS, now that there are reports that upgrading to Catalina will wipe out a users /opt/ folder.

Below you will find my steps for getting MacPorts compiled by hand on MacOS 10.15 Catalina. I am working on a clean install of Catalina and Xcode 11. If you are trying an upgrade, or using a different version, your experience may be different. If you run into problems post a comment and I’ll do what I can to help out.

And so, without further ado…

Install MacOS Catalina
Install XCode 11
Launch XCode
1. Agree to the license agreement.
2. Enter your password when the authentication dialog box opens.
3. Wait for it to finish installing components.
4. Quit XCode
Open a terminal window.
(CMD-Space terminal <return>)
sudo xcode-select --install
(enter your user password)
When the pop-up opens asking for permission to install the command line tools, click “Install”.
Agree to the license agreement, despite what it says will happen to your first-born.
Back to your terminal window, inscribe these arcane incantations:
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
sudo xcodebuild -license
(Space through the document, and then type ‘agree'<return> – The ghost of Steve Jobs will not start haunting you until at least New Years.)
cd ~/Desktop
(A window will pop up asking for access to your desktop folder. Grant it, lest the imps be released.)
curl -O https://distfiles.macports.org/MacPorts/MacPorts-2.6.1.tar.gz
tar -xzvf MacPorts-2.6.1.tar.gz
cd MacPorts-2.6.1
./configure
make
sudo make install
(Enter your user password if prompted. You may not be prompted if you get through the above steps quickly.)
echo 'export PATH=/opt/local/bin:$PATH' >> ~/.zshrc
source ~/.zshrc
sudo port -v selfupdate
(Enter your user password if prompted. You may not be prompted if you get through the above steps quickly.)

At this point you are pretty much ready to start installing ports. I say pretty much, because there are two ‘optional dependencies’ that will make your life easier:

Install Java from https://www.java.com/en/download/mac_download.jsp
Install XQuartz X11 from https://www.xquartz.org/

Install Xcode 11 On Catalina Free

OK, now you are really, really ready to install ports. 🙂

Take your fresh Catalina install out for a spin and let us know how it goes!
