In general you need to add percent escaping for components of composed URL, like

let email = "test@gmail.com"
let subject = "Feedback"
let body = "Please provide your feedback here, and we will contact you within the next 24-48 hours."
guard let url = URL(string: "mailto:\(email)?subject=\(subject.addingPercentEncoding(withAllowedCharacters: .urlPathAllowed) ?? "")&body=\(body.addingPercentEncoding(withAllowedCharacters: .urlPathAllowed) ?? "")") else { return }
