Apple announced a new rule for developers, which will permit them to only build apps that have the ability to access the internet over WiFi and not just a local iPhone. Apple said in a blog post , “Starting June 1, 2016, all new watchOS apps submitted to theApp Store must be native apps built with the watchOS 2 SDK or later.” Apple’s June 1 deadline for native apps surfaces online roughly two weeks before the company’s Worldwide Developers Conference, where it is expected to unveil new versions of iOS, OS X, watchOS, and tvOS. Apple introduced support for native apps with watchOS 2. With native app support, developers can build apps that are able to run on the Apple Watch, allowing apps to open more quickly and work more smoothly as well. The 27th annual Worldwide Developers Conference (WWDC) is all set to take place from June 13 to 17 in San Francisco. The keynote address will be at Bill Graham Civic Auditorium, followed by the rest of the week’s conference sessions at Moscone West. Developers looking to attend can apply for tickets via developer.apple.com/wwdc/register/ . The tickets will be issued via random selection process or lottery and applicants will be notified by April 25.
