If you have an earlier release of Mac OS X, you may download the latest version of Xcode for Mac OS X 10.5 (Xcode 3.0 and Xcode 3.1 Developer Tools) or 10.4 (Xcode 2.4.1 and Xcode 2.5 Developer Tools) from the Apple developer website. I'm using the latest MAC OS Catalina v10.15.4 and none of the solutions above worked. For me, I have to download Xcode from the appstore and switch to appropriate node version my site is using and npm install worked! You can now submit apps built with Xcode 12.5 beta 3 using the SDK for iOS 14.5 beta 3, tvOS 14.5 beta 3, watchOS 7.4 beta 3 for internal and external testing.
Learn about the key features available in Xcode, the integrated development environment for building apps for Mac, iPhone, iPad, Apple Watch, and Apple TV. For detailed information on updates in the latest released versions, including each beta release, see the Xcode Release Notes.

If you've install macOS Catalina on VirtualBox you'll notice a small screen resolution which we fix macOS Catalina screen resolution that can be VirtualBox Catalina resolution, which doesn't expand when you switch to full-screen mode. Unlike VMware, when you've finished the installation, you will install VMware Tools on macOS Catalina which fixes most of the things that one of them is screen resolution. Plus enhances performance, graphics, and video settings. But unfortunately, that's not applicable here. Don't worry, there's another trick to it. Here's how to fix macOS Catalina screen resolution on VirtualBox.
One of the most important parts of using an operating system is its screen resolution. When you have a huge screen resolution or even if it's not huge, it's definitely bigger than the default screen resolution of the operating system you install. In this case, you would likely wish to experience the complete resolution when you've a larger screen.

It's really annoying. Let's see how to fix macOS Catalina screen resolution on VirtualBox.
Related:Install macOS Catalina on VMware on Windows PC
Step One: Switch Off macOS CatalinaXcode Catalina Download DmgFirst, shut off the virtual machine by clicking on close on the VirtualBox. This is super-important.
When the close virtual machine prompts up, click Power off the machine then click OK.
Step Two: Edit Catalina Screen Resolution KeyAt this point, you'll need a single file of the screen resolution key and modify it for your virtual machine.
For that, you'll need to download the macOS Catalina Screen Resolution. Once it is with you, open it and replace 'macOS Catalina' with your virtual machine. I guess it would be macOS Catalina or only Catalina, in which case, you'll only need to do a simple edit
Next up, modify the screen resolution which is '1920×1080' with the resolutions tested below.
Macos Catalina Xcode DownloadStep Three: Close VirtualBoxWhile the virtual machine is closed, now you need to exit from VirtualBox. These two are really important to be closed, so make sure they aren't open. Otherwise, this would probably make the virutal machine unusable.
Step Four: Apply Fix macOS Catalina Screen ResolutionThe commands are ready to apply now. The only step to fix Catalina screen resolution is now to apply the commands which are very important.
When you're done, open Command Prompt without administrator privileges.
On this window, in order to locate the VirtualBox, copy and paste the first line of the command.
Now copy and paste the next line of the command and hit Enter. This will change the default resolution to your desired resolution.
And there you go! With this simple trick, you've fixed the macOS Catalina screen resolution permanently.
Step Five: Switch on macOS CatalinaThis should work properly without any issue if you've done all the steps correctly.
To try and see everything, switch on the macOS Catalina machine from VirtualBox.
Without you switch to the entire resolution, it will automatically start in your preferred resolution. Simply sign in and you'll enjoy the perfect resolution.
To experience the seamless resolution, from the top menu, click on View and click on Full-screen Mode. It will perfectly cover your entire screen without a side black cover.
You'll see the gorgeous Catalina wallpaper across all across the edge of your screen.
To check, from the top click on the Apple icon and select About This Mac.
Xcode Catalina Download FreeFrom the menu, click on Display tab and the screen resolution will be in front of you.
Xcode 11 Download CatalinaThe resolution will completely fit and there's no problem at all. If it's smaller or doesn't cover your screen, you may change the resolution with the steps we did and change the screen resolution this time. This is the perfect way to enjoy the ideal Mac. That's all of how to fix macOS Catalina screen resolution on VirtualBox.
