[当我尝试在Xcode的Canvas窗口中预览我的SwiftUI视图时，我的项目成功构建，但是在Canvas窗口中收到以下错误：
UVIntegration.DTXMessageError.messageRepliedWithError（“正在连接到已启动交互式代理6310“，可选（错误Domain = com.apple.dt.ultraviolet.service代码= 17“ connectToPreviewHost：无法连接到6310：Error Domain = RemoteBundleLoaderErrorCode = 17“无法加载库/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/PrivateFrameworks/XCPreviewKit.framework/Versions/Current/XCPreviewKit由于缺少引导符号”UserInfo = {NSLocalizedDescription =无法加载库/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/PrivateFrameworks/XCPreviewKit.framework/Versions/Current/XCPreviewKit由于缺少引导符号}“UserInfo = {NSLocalizedDescription = connectToPreviewHost：无法执行连接到6310：错误域= RemoteBundleLoader错误代码= 17“失败加载库/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/PrivateFrameworks/XCPreviewKit.framework/Versions/Current/XCPreviewKit由于缺少引导符号”UserInfo = {NSLocalizedDescription =无法加载库/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/PrivateFrameworks/XCPreviewKit.framework/Versions/Current/XCPreviewKit由于缺少引导符号}}）））

清理生成文件夹，然后杀死Xcode，启动Xcode，执行完整的生成可能（有时）解决问题。然后整个马戏团又开始了。我认为这对苹果有点可耻。最令人沮丧的是（至少对我而言）文档几乎不存在。这都是反复试验。主要是错误。
