1.4. Running iOS Apps on the Simulator
Problem
You’ve prepared an iOS project in Xcode and would like to run it in iOS Simulator to make sure it works.
Solution
You need to use the Scheme breadcrumb button on the top-left corner of Xcode to first select the project that you wish to run on the iOS Simulator and then select the simulator that you wish to run your app on (iPhone/iPad).
Discussion
Follow these steps:
Find the Scheme breadcrumb button on the top-left corner of Xcode’s window. This button looks like that shown in Figure 1-11.
Figure 1-11. The Scheme breadcrumb button in Xcode
In Xcode, you can have multiple projects on the same workspace. For example, at the time of writing this recipe, I have one project per recipe, added to one big project that I’ve created for this book. The left side of the Scheme button shows you the project that’s currently selected. So if I click on the left side of the Scheme button, I’ll see something similar to Figure 1-12. So go ahead and click on the left side of the Scheme button and select the project that you wish to run on the iOS Simulator.
The right side of the Scheme button lets you choose which device/simulator you wish to run your app on. I’ve selected iPhone Simulator. Go ahead and press the right side of the Scheme button to select which simulator you would like to run your app on (Figure 1-13).
