Swift was designed to address safety trade-offs as well as support the core concepts to ensure Obj-C flexible and good performances of these features: notably dynamic dispatch, widespread late binding, extensible programming. For safety, Swift introduced a system that helps address common programming errors like null pointers, as well as introducing syntactic sugar to avoid the pyramid of doom that can result. For performance issues, Apple has invested considerable effort in aggressive optimization that can flatten out method calls and accessors to eliminate this overhead. More fundamentally, Swift has added the concept of protocol extensibility, an extensibility system that can be applied to types, structures and classes, Apple promotes this as a real change in programming paradigms they refer to as protocol-oriented programming.
A survey on 8,000 developers by VisionMobile revealed that one out of five were using Swift just four months after its public launch. Compare that with a 39% usage share for Objective C (which obviously had a bit of a head start with iOS-centric devs) among device-side developers. That’s rapid adoption, to put it mildly.
Internet of Things
Plenty of developers are investing energy in something that might take a while to deliver a tangible payoff: the Internet of Things: (IoT). More than half (53%) of developers included in the report say they’re working on some form of IoT project. Interestingly, many are doing so as a side project or hobby, not their actual job. It’s no real surprise that the biggest areas of current interest within the broad Internet of Things universe are those where existing mobile platforms—namely iOS and Android—have a clear stake, such as the smart home/smart building and wearable computing markets.
Above are upcoming trends that are predicted to significantly affect the way we are doing in mobile application market. To sum up, app developers now should pay more attention to the interchange of platform for wider use of their app and the most popular coding for app building. The given information above is also clue for business owners to have more unique ideas to run a business with mobile app.
