There is always a subset of the population for which it is fashionable to try to make a new language to make things easier. It is inevitable that someone in a sufficiently large organization will try to make one, provided management supports it. Apple is a very wealthy company that is happy to sponsor R&D, had someone interested in this that they sponsored and the result was appealing enough that they decided to adopt it.

That is my understanding of how the process generally works and what I am willing to guess happened. Prior to this, they had been making incremental changes to Objective-C.

That said, from what I have seen of the syntax of both languages, swift’s syntax is nicer and that is not something that they would have been able to get from Objective-C. They already had tried syntax reform for Objective-C once in the past and abandoned it.
