iOS 10 is coming, and as with anything worthy of a base number it’s bringing a host of foundational changes. Messages is getting enhanced with a bevy of new features, Siri can now work with apps from the App Store, the Home app brings the Internet of Things one step closer to reality. Photos, texting, shopping, navigating, basically everything is being revamped or reinvented, meaning developers have their work cut out for them. This bundle of lessons is one way to make sure you’re ahead of the game and ready when iOS 10 drops, nearly 200 hours of training for just $29.

iOS 9 is here and the development frenzy has begun. It’s not too late to get in on the action though, and right now may be the best time to start with this bundle of top notch lessons that can be your for whatever you want to pay. The almost 100 hours of instruction covers iOS 9, Swift, Xcode, WatchOS 2, tvOS, and more, and all proceeds go to Project HOPE, delivering medicine, supplies, experts and medical training in response to disasters and wellness needs around the world.

For years, Apple’s software engineers have played a cat-and-mouse game, closing loopholes that let non-developers install unsigned apps on their devices. But it looks like they’re finally giving up and will let any user install anything on any Apple device — as long as they’re using Xcode 7 to do it.
