When stage set for handheld devices with iPhone release Apple was concentrated on the iOS application development. In due course it has realized that it has not a big capacities to fulfill the needs and aspirations of the handheld devices users so it has freed the iOS application development at a great degree for 3rd party developers offering them big chunk of share from the selling income likely 70% and initial success of some developers has proved App store a goldmine for new iOS 5 developers coming into store.
After laps of some period iOS 5 developers have got another opportunity in form of Android and they have started development on the both platform but they were not getting enough financial returns on Android as they were used to getting on iOS thus they would like to stay with Apple with hate or love anyway. The most promising category in iOS app development was iOS games so many game developers became iOS game developers and came up with intuitive and innovative iOS games and this high downloading rate was remain constant for long time till the Android has updated its Android OS with Jelly Bean.
Now iOS developers were observing iOS app development trends change in favor of the businesses and they set stage for the highly functional and useful iOS apps with iOS app development. Here challenges were complex enough due to variations and variety of the businesses because each business was coming with specific or bespoken requirements that not only demand the understanding of that business niches but also expect thorough research for the business mechanisms and expectation of the all components of the businesses like owners, employees and customers as well as other related businesses.
At one hand iOS app development is not an easy task as it requires latest knowledge of the Objective C, HTML5, iOS SDKs and third party tools like Cocos2d and Unity 3D for iOS game developers Thus getting mastery over these all long curved languages and technologies are little bit challenging as well as time consuming affair. Thus once iOS 5 developers enter into the market they naturally expect higher return of their hard work but stiff competition doesn't allow to do that so they intimidate and leave the playground, but those stay and get mastery over development as well dealing with market they win the game indeed and they only can create robust iOS applications which are highly demanded by the modern users.
With the release of iPhone 5 many iOS 5 developers shifted from iOS development to iOS 6 because it came with the new iOS 6 with more functionalities and more features thus again they have to jot down in learning and creating challenging applications.
