By Keep in mind that, despite the iOS Simulator’s many virtues, running apps in the Simulator is still not the same thing as running them on the iPad. Here’s why: • Different frameworks: The Simulator uses Mac OS X versions of the low-level system frameworks, instead of the actual frameworks that run on the device. This iOS emulator is well-known for attractive GUI, app compatibility, rich displays and the selection to download apps from the iOS app store creates it the most recommended and freely accessible ios emulators in this list. That means that occasionally some code may run fine in the Simulator but not on actual iOS devices. Although the Simulator is useful for testing functionality, there’s no substitute for debugging the app on the device itself if you want to find out how it will really run. • Different hardware and memory: The Simulator uses the Mac hardware and memory. To accurately determine how your app will perform on an honest-to-goodness iOS device, you have to run it on a real iOS devices. • Different installation procedure: Xcode installs your app in the Simulator automatically when you build the app using the iOS SDK. It’s a different kettle of fish to install your app on the device for testing. The world’s most popular cross-platform virtualization software enables you to, PC, Linux, or Oracle Solaris machine. Oracle VM VirtualBox for Mac is a general-purpose full virtualizer for x86 and AMD64/Intel64 hardware, targeted at server, desktop and embedded use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software.

And, by the way, you don’t have a way to get Xcode to install apps from the App Store in the Simulator. • Lack of GPS: You can’t fake the Simulator into thinking that it’s lying on the beach at Waikiki.

If your application’s user interface can respond to touch events involving more than two fingers, you need to test that on an actual device. (The motion of two fingers in itself is a tad limited in the Simulator — you can’t do two-figure swipes or drags.) • Accelerometer differences: You can access your computer’s accelerometer (if it has one) through the UIKit framework. Its reading, however, will differ from the accelerometer readings on an actual iPad. • Differences in rendering: OpenGL ES (Open Graphics Library for Embedded Systems, in other words) is one of the many 3D graphics libraries that works with the iOS SDK. It turns out that the renderers it uses on devices are slightly different from the ones it uses in the iPad Simulator. As a result, a scene on the Simulator and the same scene on a device may not be identical at the pixel level. • Telephony: You can’t make a phone call on the iPhone simulator. 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 iPhone 4/4S (3.5″), iPhone 5/5S (4″), iPhone 6S/7 (4.7″) and iPhone 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 iOS simuator for performance, but as the name indicates, it’s just a simulator, not a real device emulator like Smartface iOS emulator.
