如何在xcode 7模拟器或设备上运行应用程序？

Question

Before I updated from xcode 6 to 7, it was just right next to the run and stop button.

When i just click on the run button, it opens the iphone 5 simulator and from the simulator's menu, if i choose Hardware > device > iphone 6 plus, it's just completely black. If I try to run the app again, it just says that it's running on iphone 5 in Xcode.

How do I choose a different simulator?? or run on a physical device connected to the macbook?

This worked seamlessly on xcode6 with the use of the device dropdown menu beside the run and stop button. but now, that menu is gone.

Answer 1

In one of the pre-versions of Xcode 7 I had the same issue. The problem was, that there were no simulators installed.

Go to Xcode -> Window -> Devices a window will pop up. Click on the plus button in the bottom left corner and configure some devices.

The device selector should show up in Xcode.

Answer 2

Turns out Xcode did not finish downloading. There was an error when I checked the update. I made it complete the download and xcode is okay again
