From Xcode project right click and Add File to "projectName"there I created a NewFolder "ABCD"name and added to same "ABCD" empty folder to the project its in Blue colour, I expected its in Yellow Color, What the files which I added inside Blue Colour folder files are not compiling in X-Code all files which added in Blue Colour folder say file is not found after compiling the code.
从 Xcode 项目右键单击，然后Add File to "projectName"我创建了一个 NewFolder"ABCD"名称并将其添加到相同的“ABCD”空文件夹到项目中，它是蓝色的，我希望它是黄色的，我在蓝色文件夹文件中添加的文件没有编译在 X-Code 中，所有添加到 Blue Color 文件夹中的文件都说在编译代码后找不到文件。
Is there any why that default, I added folder are link related to the project?

If you simply drag drop a file and choose Create Folder reference, it will add as a blue folder. Please make sure you select Create Groups from the pop dialogue and make sure u have selected all the targets in Add To Targets section.
如果您只是简单地拖放文件并选择创建文件夹引用，它将添加为蓝色文件夹。请确保您从弹出对话框中选择创建组，并确保您已选择添加到目标部分中的所有目标。
Like this
像这样
It will be added as yellow
它将被添加为黄色
Group-> With groups, Xcode stores in the project a reference to each individual file. This can lead to problems:
Group-> 通过组，Xcode 在项目中存储对每个单独文件的引用。这可能会导致问题：
Folder references-> Folder references are simpler. You can spot a folder reference because it shows up in blue instead of yellow.
文件夹引用-> 文件夹引用更简单。您可以发现文件夹引用，因为它显示为蓝色而不是黄色。
