Every so often Apple comes up with a "Feature" that so small and so annoying that begs the question as to whether they ever consult with a user. YES! Delete confirmation is an unnecessary addition to IOS and we can only hope that some security patch will remove it
No, Apple doesn't consult with users. Instead, they see what users do with their phones and often introduce features based on what they perceive as a real need. This is one such feature. Daily, multiple users come here to these user only forums begging for help to recover an accidentally deleted text message. In most cases, the only way to get the message back is to restore from backup, which often people simply don't have.
So, this very small change was introduced to help the countless thousands of users to ensure when they use swipe to delete that they truly do want to delete the message.
Are you aware there is another simple method to delete messages that will not ask you to confirm you want to delete? Yes, Apple provided the best of BOTH worlds to users. Simply use the Edit/Tap Messages(s)/Tap Trash icon and voila, message(s) delete without confirmation. That can't be any more cumbersome could it? It's three steps, just like it was before on swipe to delete.
