You have to make sure that the file name of your image has a format like .png or .jpg at the end otherwise it will not work. Also, before adding your image, you have to make sure that the image file is in your "Assets.xcassets" folder within your project. This can be done with a simple drag and drop. Also, make sure when you've added your image to your storyboard that the image name in the top left also matches the real image file name. I would try looking into Constraints too. Hope this helps. Good luck with your App.

我也遇到过同样的问题。我尝试了不同的解决方案，但都无济于事。然后我意识到，只有当我直接将应用程序安装到设备中，应用程序仍然连接到xcode时，图像才不可见。如果我断开它，然后打开应用程序的图像是可见的预期。 这可能是一个xcode错误。

我也面临同样的问题。

添加一个新的图像集到XcodeAssets。 将图像添加到映像集中。 添加图像视图，以启动屏幕和设置您的imageset为图像 在Imageview的属性检查器中，取消选中“清除图形上下文” 清理生成文件夹并再次运行。

我有启动屏幕文件命名，但它不存在。当我删除这个我的发射图像出现。

非常令人沮丧。最终成功的解决方案:

是否硬重启设备 删除应用程序 从Xcode安装app
