If you are testing an app with a deployment target of iPhone or universal, you can test on either a simulated iPhone or a simulated iPad. Note: If you are testing an app with a deployment target of iPad, you can test only on a simulated iPad. Figure 1-1 Simulated iPhone running the HelloWorld app Xcode builds your project and then launches the most recent version of your app running in Simulator on your Mac screen, as shown in Figure 1-1. To run your app in Simulator, choose an iOS simulator-for example, iPhone 6 Plus, iPad Air, or iPhone 6 + Apple Watch - 38mm-from the Xcode scheme pop-up menu, and click Run.

When testing an app in Simulator, it is easiest to launch and run your app in Simulator directly from your Xcode project. The first way is to run your app in Simulator, and the second way is to launch Simulator without running an app. There are two different ways to access Simulator through Xcode. For more detailed information on interacting with Simulator and using it to test and debug your apps, refer to the later chapters in this guide. You can perform these steps using your own iOS app or, if you do not have an app to use, with the HelloWorld sample code. The chapter presents the basics of using Simulator. You interact with Simulator by using the keyboard and the mouse to emulate taps, device rotation, and other user actions. Simulator app, available within Xcode, presents the iPhone, iPad, or Apple Watch user interface in a window on your Mac computer.

For Xcode 9 and later, see Simulator Help by choosing Help > Simulator Help in Simulator. It is much better than the freeware emulators available.The information in this document is deprecated in Xcode 9. VirtualPC is a commercial PC emulator for Mac. It has no sound support, has only standard VGA video, and according to the authors, no updates to PCx will be released. It has complete 486SX emulation, with partial 586 emulation. PCE was written in ANSI-C and is licensed under the GNU General Public License, Version 2. The emulation is complete enough to boot DOS and run most DOS applications. It emulates most of the hardware of an IBM PC 5150. The Darwine project intends to port and develop Wine as well as other supporting tools that will allow Darwin and Mac OS X users to run Windows Applications. DOSBox has already been ported to many different platforms, such as Windows, BeOS, Linux, MacOS X.ĭOSBox also emulates CPU:286/386 realmode/protected mode, Directory FileSystem/XMS/EMS, Tandy/Hercules/CGA/EGA/VGA/VESA graphics, a SoundBlaster/Gravis Ultra Sound card for excellent sound compatibility with older games. DOSBox is a DOS-emulator that uses the SDL-library which makes DOSBox very easy to port to different platforms.
