I cannot get a Launch Image to be displayed on my app, whatever I try.无论我尝试什么，我都无法在我的应用程序上显示启动图像。 For context, this is a completely new, 100% SwiftUI project and is in its very early infancy.就上下文而言，这是一个全新的 100% SwiftUI 项目，处于非常早期的起步阶段。

Everything builds & runs perfectly fine, but I just cannot get any launch image customisation going...一切都构建和运行得很好，但我无法进行任何启动图像定制......

My Info.plist :我的Info.plist ：

My assets:我的资产：

I've tried cleaning, deleting DerivedData, reinstalling app on device + sim but to no avail...我试过清理、删除 DerivedData、在设备 + sim 上重新安装应用程序但无济于事......

What am I doing wrong?我究竟做错了什么？

I ran into a similar issue before and got it fixed by restarting my phone.我之前遇到过类似的问题，通过重启手机解决了这个问题。

When using launch storyboards I found that if the images that I used where too large it would launch with a black screen.在使用启动故事板时，我发现如果我使用的图像太大，它会以黑屏启动。

I reduced the size of the images I was using (one was reduced to 900px by 700px) but I don't know the magical size that sorts it, I then rebooted my iPhone and it started to work fine.我缩小了我正在使用的图像的大小（一个缩小到 900px x 700px）但我不知道排序它的神奇大小，然后我重新启动了我的 iPhone，它开始工作正常。

I don't know if the size issue would affect normal launch images but it may be worth giving it a try with a smaller image.我不知道尺寸问题是否会影响正常的启动图像，但可能值得尝试使用较小的图像。
