I'm very new to Xcode and I am trying to make a very simple view app like Hello Wolrd with button and label.
But when I'm in the main.storyboard editor, I can put button and label, but they do not show up. They do when I move them, but once placed they only the selection rectangle.
I can still use them in the viewcontroller.swift and it works perfectly in the simulator.
I don't have this problem when I open a project for macOS.
I tried some solutions I found her but they does not seem to fix the issue.
Issue in Xcode 8.1 Storyboard layouts
Layout issues after updating to Xcode 8
Is it another Xcode 8.1 bug ? Or is there something I do wrong ?
Thanks !!
