Ios9 application real machine test

In Xcode 7.0, Apple made a lot of changes in the Development Permission and removed some restrictions on app testing. In versions earlier than Xcode7, apple only provides Xcode downloading and real-machine testing functions to developers with registered developer accounts ($99). However, in Xcode 7.0, developers do not need to register a paid developer account. If they are interested, they can use a free Apple ID to test the app on their devices for free.

Next, we will explain how to perform a real machine test in Xcode 7.0. First, choose Product | Destination | real machine on the menu bar (the real machine in this book is a Mac iPhone) command, as shown in Figure 1.45. Then, when you run the program again, the program will be displayed on the real machine, rather than in the iOS simulator.
