can`t open storyboard on stable version Xcode

Question

I made a mistake by opening my project in a new beta version of xcode

Now I can not open it with a stable version because

The document “Main.storyboard” requires at least Xcode 11.0.
This version does not support iOS 13.0 system colors. Open this document with at least Xcode 11.0.

On Saturday, I planned to publish the application. and it can not be published with the beta versions.

I need to run the application on the standard version of xcode

Is there any way to fix my situation?

Answer 1

文档“ Main.storyboard”至少需要Xcode 11.0。此版本不支持iOS 13.0系统颜色。至少使用Xcode 11.0打开此文档。

解决了

打开情节提要作为源代码，然后首先删除以下行：

<capability name = "iOS 13.0 system colors" minToolsVersion = "11.0" />

还有那里的一切

cocoaTouchSystemColor

然后在“界面”构建器中还原所需的颜色。
