Hey there, sorry to hear you're stuck with this MapFileParser.sh: Permission denied error in Xcode 15.1—especially since you don't use CocoaPods and reinstalling Xcode didn't fix it. Let's walk through some practical workarounds that don't rely on Pods:

手动赋予脚本执行权限
The MapFileParser.sh script is part of Xcode's core installation files. You can fix its permissions directly via Terminal:
1. Open Terminal and navigate to the script's directory:
```
cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/
```
2. Run this command to grant execution rights (you'll need to enter your Mac's admin password when prompted):
```
sudo chmod +x MapFileParser.sh
```
重置Xcode命令行工具并验证完整性
Misconfigured command line tools can sometimes trigger unexpected permission issues:
1. In Terminal, reset the Xcode command line tools path:
```
xcode-select --reset
```
2. Open Xcode, go to Xcode > Settings > Locations, and make sure the Command Line Tools dropdown is set to "Xcode 15.1".
3. You can also try reinstalling Xcode's additional components: Open Xcode > Open Developer Tool > More Developer Tools, download the component package matching your Xcode 15.1 version, and install it.
清理Xcode缓存与派生数据
Corrupted cache files might be causing this permission error:
1. Close Xcode completely.
2. Delete derived data via Terminal:
```
rm -rf ~/Library/Developer/Xcode/DerivedData
```
3. Clear Xcode's app cache:
```
rm -rf ~/Library/Caches/com.apple.dt.Xcode
```
4. Restart Xcode and try building your project again.
用新项目测试排查问题
To rule out project-specific issues, create a new empty iOS project in Xcode 15.1 and try building it. If the error doesn't appear here, the problem might lie in your original project's build configurations—check your project's Build Phases for any custom scripts that might reference MapFileParser.sh incorrectly, or verify that your project folder has proper read/write permissions.
