let platforms = ["iOS", "macOS", "tvOS", "watchOS"]

for os in platforms {
    print("Swift works great on \(os).")
}

When I run the code above in playground, it prints the final element of the array only. When run my output is:

Array of 4 String elements
[several blank lines]
 "Swift works great on watchOS.\n"

Expected behavior?

Sonoma 14.2, Xcode 15.0.1

edit: running the swift code from the command-line displays each element.

When I run in playground, get this

Swift works great on iOS.
Swift works great on macOS.
Swift works great on tvOS.
Swift works great on watchOS.

Thanks for the reply,

I'm not allowed to insert an image or to link to an image, unfortunately. I wanted to show exactly what I was seeing

I have two panels:

The left-hand panel, where I'm entering code, has line-numbers. The right-hand panel shows only partial output.

the screencap can be seen at http // jocala dot com / play.png

You need to show the debug area. You can do this under the View menu, or using ⇧⌘Y

See this

PS to insert image I use Dropbox (allowed link) and then change the last bit of url (dl=0) to raw=1 then it should work

Thanks! I'm all sorted out and proceeding onward. Day seven!
