找不到在Xcode中设置本地路径的地方，请问该如何解决此问题？

这个报错的核心原因是Xcode的运行Scheme未正确关联可执行产物，或者构建产物路径配置异常，导致调试器找不到要启动的可执行文件。按以下步骤排查：

1. 检查Scheme的可执行文件关联 #

• 点击Xcode顶部工具栏的Scheme下拉菜单，选择Edit Scheme...
• 在弹出窗口左侧选择Run，切换到Info标签页
• 确认Executable下拉框已选中synctex对应的可执行目标（产物类型为com.apple.product-type.tool，与报错信息中的参数一致）
• 若下拉框为空或无有效选项，点击下拉框选择Other...，手动定位到项目构建后的可执行文件（默认路径为DerivedData/[项目名]/Build/Products/Debug/[synctex可执行文件名]）

2. 验证目标构建设置 #

• 在项目导航栏选中synctex目标，打开Build Settings标签页
• 搜索Product Name，确认名称无误；搜索Executable Path，确保值为默认的$(EXECUTABLE_NAME)，无需手动修改
• 检查Build Products Path，确认路径为$(BUILD_DIR)，保证产物输出路径有效

3. 清理并重新构建 #

• 执行Product > Clean Build Folder（快捷键Cmd+Shift+K），清除旧的构建缓存
• 执行Product > Build（快捷键Cmd+B），等待构建完成后再尝试运行

4. 重置DerivedData目录 #

• 打开Xcode的Preferences > Locations，找到Derived Data的路径
• 手动删除该路径下对应项目的文件夹，然后重新构建项目
