ForEach in SwiftUI

Question

When use ScrollView and ForEach looks like the following code :

ScrollView(.horizontal,showsIndicators: false) { HStack { ForEach(self.QUOTES, id: \.self) { qt in Text(qt) } } }

Its ok and no problem. But when I want to use any code (like adding a image) in ForEach block like the following code :

ScrollView(.horizontal,showsIndicators: false) { HStack { ForEach(self.QUOTES, id: \.self) { qt in Text(qt) Image(systemName: "a.square.fill") .resizable() .frame(width: 40, height: 40) } } }

I get the following error while writing : Unable to infer complex closure return type; add explicit type to disambiguate

Have you tried putting your Text and Image in some kind of stack? Stack or Hstack? Honestly, and meant with no offense, this is pretty basic SwiftUI. Maybe your HStack is too... outer... in the FroEach. But stat with something more simple≥ Maybe A List. Or maybe a View. Move that into it's own struct. (My choice? a Button. Who cares if it doesn't do anything. Get it laid out like you wish.) As is, you need to either Group your code or use a stack of some source. But also? As is, your question doesn't help to say which. — user7014451

The ForEach struct needs to contain a single view so you'll need to group the text and image or embed them in a stack depending on how you want the layout to render.

ScrollView(.horizontal,showsIndicators: false) { HStack { ForEach(self.QUOTES, id: \.self) { qt in Group { Text(qt) Image(systemName: "a.square.fill") .resizable() .frame(width: 40, height: 40) } } } }
