如何无需Xcode删除Derived Data及Xcode 9.2升9.3故障解决

Hey there, let's work through your Xcode problems step by step!

You've got a few straightforward options here:

Option 1: Use Finder #

• Open Finder, hold down the Option key, then click the Go menu in the top bar.
• Select Library from the dropdown (this only shows up when holding Option).
• Navigate to Developer > Xcode > DerivedData.
• You can either delete the entire DerivedData folder or just the subfolders inside it (each subfolder corresponds to a project's build data).

Option 2: Use Terminal #

Open Terminal and run this command to wipe all Derived Data at once:

rm -rf ~/Library/Developer/Xcode/DerivedData/*

Note: rm -rf is a powerful command—double-check the path before hitting enter to avoid deleting unintended files.

Let's break this down into parts to tackle each problem:

First: Fix App Store Update Error #

Even with enough storage, App Store cache glitches often cause this. Try these steps:

• Open Terminal and run these commands to reset App Store processes:

  killall -HUP StoreKitAgent
  killall AppStore
  

• Quit the App Store completely, then reopen it and try the update again. If this still fails, we'll focus on the clean install route.

Next: Fix XIP File Won't Unzip #

If the official XIP won't extract, here's what to do:

1. Verify file integrity:
   Run this command in Terminal to get the file's SHA256 hash (replace the path with your XIP file's location):

   shasum -a 256 /Users/YourUsername/Downloads/Xcode_9.3.xip
   

   Compare this hash to the official SHA256 value listed on Apple's Xcode download page. If they don't match, the file is corrupted—re-download it.
2. Extract via Terminal:
   If the file is intact, use Terminal to extract it (this often bypasses Finder-related issues):

   xip -x /Users/YourUsername/Downloads/Xcode_9.3.xip
   

   If you get a permission error, try adding sudo before the command (you'll need to enter your admin password):

   sudo xip -x /Users/YourUsername/Downloads/Xcode_9.3.xip
   

Finally: Remove All Xcode Residual Files #

CleanMyMac3 spotted leftovers, but you can also manually delete these key folders to ensure a clean slate:

• Delete simulator data: ~/Library/Developer/CoreSimulator
• Delete Xcode app support files: ~/Library/Application Support/com.apple.dt.Xcode
• Delete Xcode cache: ~/Library/Caches/com.apple.dt.Xcode
• Delete device logs: ~/Library/Logs/CoreSimulator

After deleting these, restart your Mac to clear any lingering processes. Then try re-extracting the XIP file or downloading Xcode from the App Store again.
