Developing a mobile application with a platform-based approach (Java and Objective-C/Swift) is not as easy as it looks.
There are so many details one needs to consider like platforms, screen technologies, OS versions etc.
To avoid these problems, many companies and developers are now using Cross-Platform Mobile Application Development Platforms.
Nowadays, Cross-Platform solutions are chosen by 5 of the Top 10 Fortune 500 companies.
Gartner estimates that more than 75% of the enterprises will use at least one mobile application development platform by 2020.
Main part of the development process requires adaptation of the application to different screen sizes and resolutions on different devices, just like the different screen sizes of i Phone 4/4S (3.5″), i Phone 5/5S (4″), i Phone 6S/7 (4.7″) and i Phone 6S/7 Plus (5.5″).
It’s a well-known fact that virtual device emulators and simulators are very slow on many platforms (like Android).
Hence, the real product may appear different on real devices than it appears on virtual emulators in many cases.
Moreover, network operations may present different cases on real devices.
For instance, Xcode uses an i OS simuator for performance, but as the name indicates, it’s just a simulator, not a real device emulator like Smartface i OS emulator.
Thus, most of the developers choose real devices for testing.
It might look OK at first glance, but what about i OS development on a Cross-Platform solution?
