Answer 1

有两种更改ViewController名称的方法：

1） 例如：类LoginViewController：UIViewController-只需选择“ LoginViewController”，然后右键单击->重构->重命名

这将更改名称文件名，类名，并照顾情节提要的类名。

2）如果无法使用方法1，则手动重命名文件Name（.swift），则必须转到情节提要，并替换视图控制器的类名。您可能对网点有疑问。

3）之后，关闭Xcode，然后再次启动您的项目。

Answer 2

您在情节提要中的控制器中有一个textField或textView或UILabel，

1-打开情节提要

2-单击UIViewController（具有已更改的类的新名称的ViewController）

3-移除名称为TextOutput的插座

4- ReConnet（如果需要），并且准备好了

Answer 3

我通过在身份检查器中为“自定义类”设置“模块”来解决了该问题
