Xcode is currently on version 11.3, and is available to download from the Mac App Store. How to edit photos with macos photos app iphone. Writing Code in Xcode The core of the Xcode suite is the IDE, which itself is also called Xcode. To distribute a macOS app through the Mac App Store, you must enable the App Sandbox capability. App Sandbox Entitlement. A Boolean value that indicates whether the app may use access control technology to contain damage to the system and user data if an app is compromised. Following last week's disclosure of new iOS malware called XcodeGhost, which arose from malicious versions of Xcode hosted on third-party servers, Apple has outlined instructions for developers to ensure the version of Xcode they are using is valid. When downloading Xcode from the Mac App. Hello, I use Avast antivirus and it finds a virus 'MacOS:BitCoinMiner-AS Trj' The virus was detected in Xcode application ('Application/Xcode.app/contents/Framework.
Industry NewsiOS developers were the target of a recent malware attack, not Apple Store, although malicious code was spread through many apps downloaded via the online app store. Attackers inserted malicious code into a version of Xcode, Apple’s official app development software. The malicious version, dubbed XcodeGhost, was uploaded to China-based Baidu, a cloud service.
A link to download XcodeGhost was shared in Chinese developer forums, which lead developers to download the malicious version in order to create infected apps they submitted to Apple Store. But why would a developer download Xcode from a source other than Apple’s website?
According to an interview SCMagazine.com did with Palo Alto Networks, slow Xcode (size: three GB) download times in China (read: hours) could drive Chinese developers to download from unauthorized sources on Baidu instead of from Apple directly. Another article from TidBits blames it on China’s bandwidth limitations and restrictions to accessing foreign servers. But regardless, that’s still a big security risk for a developer, or any user, to take.
While the current version of XcodeGhost can’t actually be used to directly phish iCloud passwords, by changing just a few lines of code, it can be used to phish any kind of password, according to Palo Alto Networks researchers. The effect of XcodeGhost on infected apps is similar to adware or tracking frameworks, rather than malicious malware, as Appthority reported.
The more technical description of what infected apps can do involves sending request to servers with all kinds of device identifiers, with a response that can trigger different actions, like opening a URL. Check out more details by Appthority.
There were at least 39 confirmed applications containing XcodeGhost, removed by Apple from its store, including WeChat, which has also fixed the security flaw in its newest iOS version. Apple has also sent an email to affected developers, urging them to recompile using the official Xcode software and re-submit apps, according to an update from Palo Alto Networks.
Three command and control (C2) servers that communicated with the apps being hosted on Amazon were also identified and shut down, according to Threatpost, and Baidu has since removed links to download the malicious software.
XcodeGhost has been spreading since March, with download links indexed and promoted in search engines for over six months now, making it likely that far more infected apps are out there (unconfirmed numbers estimating the total as hundreds and even thousands).
How Can Developers Protect Themselves?
Most of the developers that were affected were located in China. To find out if you’re running XcodeGhost, the InfoSec Community Forums from SANS advises that developers check for a certain file in their software:
- Check for Library/Frameworks/CoreServices.framework/CoreService in SDK/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/
- Always download software from the official source
- Check any provided hashes (MD5/SHA1)
Validate Your Version of Xcode
Apple also released instructions on how to validate your version of Xcode:
- Run the following command in Terminal on a system with Gatekeeper enabled:spctl --assess --verbose /Applications/Xcode.app where /Applications/ is the directory where Xcode is installed.
- The tool should return the following result for a version of Xcode downloaded from the Mac App Store:
- /Applications/Xcode.app: accepted source=Mac App Store
- For a version downloaded from the Apple Developer website, the result should read either
/Applications/Xcode.app: accepted source=Apple or
/Applications/Xcode.app: accepted source=Apple System
Any result other than ‘accepted’ or any source other than ‘Mac App Store’, ‘Apple System’ or ‘Apple’ indicates that the application signature is not valid for Xcode.
Download a clean copy of Xcode and re-compile your apps before submitting them for review.
Apple also recently announced they would provide an official source for developers in the People’s Republic to download Xcode domestically from local China-based servers in response to XcodeGhost.
How Can Users Protect Themselves?
Affected users include those that downloaded apps in mainland China, Taiwan, Hong Kong or Macau - that is, anyone that downloaded an app from Apple’s App Store serving Greater China, according to 9to5mac.com. Here’s what users can do to protect themselves:
- Check for HTTP traffic to http://init.icloud-analysis.com in your firewalls or proxies logs.
- Check for traffic to the IP addresses listed.
- Remove the apps listed as malicious, which, according to Palo Alto Networks, includes:网易云音乐 2.8.3

Program Manager for Research and Development Mike Hanley of our security research team, Duo Labs, also advises:
This is an important opportunity to remember the impact that development tools can have on the security properties of any piece of software. Attacks against various elements of the supply chain are discussed more and more, and this is no exception. Good software development practices and the best intentions can still be thwarted when an attacker inserts themselves into the development path in this way. Always use trusted development tools and services to ensure you are not bringing essentially what amounts to a Trojan horse into your development shop.
Xcode is an Apple-created developer's toolkit for iOS and macOS app development. Xcode is one of the best tools for developers, but projects can take up a lot of space on your Mac hard disk.
The app also generates a lot of 'temporary' cache files that will grow over time until they become a hidden monolith of space waste. More than just wasting space, the junk can slow Xcode down, sometimes making it non-responsive.
When this happens you need to clean Xcode by completely removing old cache files and the app itself before doing a fresh Xcode install.
If you think you don't need help uninstalling Xcode, think again. A normal uninstall will not remove all the cache junk.
So to be very clear, when removing Xcode do not just move the icon to the Trash bin. This doesn't uninstall Xcode app completely, only parts of it. Caches, supporting files, your old builds, and so on — will remain on your drive in multiple directories and libraries.
Don't worry, we'll show you how to safely and, most importantly, completely remove Xcode from your Mac.
How to uninstall Xcode manually
If you want to get your hands dirty then you've come to the right place, but before you start, please note the following:
Manually removing files comes with some risk. If you don't follow the instructions carefully, you could experience unintended consequences. We assume no responsibility for what may occur from a manual app removal.
If you're up for the challenge, please carry on. If you would prefer the safer methods, go ahead and skip this section.
Now that we've cleared this up, here’s how to get Xcode off your Mac by hand:
- Open the Applications folder
- Drag the Xcode icon to the Trash
- Clean out the Trash bin
Lync web app not installing on mac. This will delete the main part of the app. Now, to the rest of the Xcode files.
- Open Finder.
- In the top menu, choose Go.
- Go to Folder..
- ~/Library/Developer/
- Find the Developer folder.
- Delete it.
https://everwebsite339.weebly.com/blog/burner-phone-app-mac. If you had earlier versions of Xcode, like 7 or 8, they leave footprints all over the place. To remove these remnants of old Xcode iterations follow these steps:
- Open Terminal.
- Run: sudo /Developer/Library/uninstall-devtools --mode=all
- Confirm your admin password.
- Wait until the scripts are done running.
- Quit Terminal.
The only thing left is getting rid of Xcode application caches. In some versions of the app they are left even after the purging, so visit this directory to make sure you have no files stored there.
~/Library/Caches/com.apple.dt.Xcode
If you find any files, clean up the folder.
Once all traces of Xcode have been removed, reinstall the app and you should enjoy a much faster experience. You’ll also have more space on your hard disk to play with.
How to quickly remove old Xcode build files
If you think the manual method sounds too risky and complicated, we’re going to show you a much better way to remove old Xcode build files. No need for dirty hands and crossed fingers, you just need to download an uninstaller app like CleanMyMac X.
Follow these steps to easily remove old Xcode build files:
- Launch CleanMyMac X
- Click on System Junk module
- Click Scan
- When the scan finishes click on Review details
- If you only want to clear Xcode files click Deselect All before you start
- Now click on Xcode Junk
- Select old iOS simulators, Xcode Derived Data (the old project builds), and old caches you don’t need anymore
- Click Clean
In the example above we were able to free up almost 15GB of wasted space. Not bad for a couple minutes of work. Can you do even better?
How to quickly remove Xcode
The fastest way to get an Xcode-free Mac is to download CleanMyMac X for free and use its uninstaller tool. This way the whole process will only take a couple of minutes and you won’t have to worry about the leftover files or deleting the wrong thing with a manual removal.
Here’s how it works:
- Launch CleanMyMac X.
- Click on the Uninstaller tab.
- Find Xcode on the list and select it.
- Click Uninstall.
Now, dealing with caches and stray parts:
- Choose System Junk tab.
- Run Scan.
- Click Review Details.
- Scroll to the bottom and choose Xcode junk.
- Hit Clean.
Xcode junk removed
Whether you want to uninstall Xcode completely or just get rid of old Xcode junk, we recommend you take action. You’ll gain more storage space and a lighter, cleaner, and faster Xcode experience.
