I’ve edited your post for readability. When you enter a code block into the forum, precede it with a line of three backticks and follow it with a line of three backticks to make easier to read. See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.
What language is this?
Hi Kevin thanks for the help, this is swift, I upgraded to xcode 9.3 and this started happening. It worked great before.
Sorry, don’t know anything about Swift. Maybe someone else can help. We’re mostly focused on web dev here, but I’m sure someone has some idea.
