Bloomberg recently reported that Apple has hired former executives from Amazon and Google to help developing its software.
Not many details were given, but at least Apple has confirmed this rumor. Jon McCormack will be the Vice President for a software role. His LinkedIn profile confirms this.
While more details are unclear, Apple has a lot going on in regards to software with a focus on reliability and performance for iOS heading into WWDC and efforts on a cross-platform solution for macOS/iOS.
Apple has also hired John Giannandrea, Google's former Chief of Search and Artificial Intelligence.
