The iPhone Messaging app, better known as iMessages in some English-speaking countries, is an instant messaging application not far from others such as WhatsApp or Facebook Messenger. In Spain we are not very familiar with this application and we tend to prefer non-native, even interacting with iOS users, however, Apple remains a bet on it because it has a large niche of users. Message users have lost the ability to edit messages, however Apple is already considering how to use them.
Now AppleInsider You have gone through a list of new patents in the United States of America and have acquired a patent related to the use of Curious Messages. In this patent for the Messaging User interface we can see that keeping the Haptic Touch in the message opens a context menu that will allow us to make various choices, among them we not only get the most common, but also the possibility of deleting the message and the "Show edit …" function. Undoubtedly this means you may have seen a list of edits made in the message, something that has existed for a long time on Facebook, for example.
Messages is certainly one of the best native iOS apps and yet few of us give it the right use, I am a beginner. However, As with SpaceTime, its main limitation is that it can only be used between users with iOS or macOS devices, And that in a world where Apple's market share is too small stands as a major obstacle that can't easily be overcome. In any case, this new way of communicating with Messages is a combination of Apple and its development.
