How to handle the prompt "Building for iOS Simulator..." when running the App?

If an error "Building for iOS Simulator, but the linked and embedded framework 'xxx.framework' was built for iOS + iOS Simulator." appears when running an App integrated with RoomKit iOS SDK, the cause and solution are as follows:

After Xcode version 12.3, it is disabled by default to use Framework with iOS + iOS(Simulator) dual-platform architecture. You can select "TARGETS > Build Settings > Validate Workspace" in Xcode and set the value of this parameter to "YES" to continue using traditional Framework.
