How did you develop the screen? Preview is not supported in the ‘compose for ios’ project.

I don’t use preview feature. I use the real devices.

It’s like shadowboxing blindfolded. I respect you.

You can use the preview in the android side for now and expect that it's going to be the same for other platforms
