In Xcode 6.1.1, you can view the NSLog output by doing the following. However, I’m not sure if it lets you see logs from too far back in time. I’ve only seen it go back up to a couple hours.
In any case, here are the steps:
- In Xcode, go to Window -> Devices.
- Select your device in the left panel.
- Click the little arrow as shown in the screenshot below.
