NSExtensionPrincipalClass引发iOS应用验证与安装冲突问题求助

我正在开发一款为Shortcuts应用提供动作集合的iOS应用（类似Sindre Sorhus的Actions应用）。

验证/提交阶段错误 #

在验证或分发构建归档/版本时，验证失败并出现以下错误：

Validation failed
Missing Info.plist values. No values for NSExtensionMainStoryboard or NSExtensionPrincipalClass found in extension Info.plist for iOS App.app/PlugIns/iOS App Intents.appex. (ID: c4b0b508-eb81-4570-92c8-448c1c2624ca)
Validation failed
Missing Info.plist values. No values for NSExtensionMainStoryboard or NSExtensionPrincipalClass found in extension Info.plist for iOS App.app/Watch/watchOS App.app/PlugIns/watchOS App Intents.appex. (ID: 04cb75a2-f3eb-4a5d-b338-df05858fdc13)

添加字段后的安装错误 #

在每个Info.plist中添加键值对NSExtensionPrincipalClass: $(PRODUCT_MODULE_NAME).ShortcutsAppIntentsExtension后，验证/提交错误得以解决。但该字段的存在导致调试和发布版本安装失败，出现以下错误：
