Here's a possible fix:

func addSpaceAfterLinks(_ content: String) -> String {
    let pattern = /https?:\/\/(www\.)?[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()@:%_\+.~#?&\/\/=]*)(?![\n\s])/
    
    let modifiedContent = content.replacing(pattern, maxReplacements: 10) { match in
        content[match.range] + " "
    }
    
    return modifiedContent
}

But the regex still needs fix. It cannot handle contents like

What is the current regex? A simple fix would be to exclude unicode characters.

No regex currently exists.
