Xcode 6 iOS Simulator does not remember app settings

Question

I just installed Xcode 6.0.1 (coming from Xcode 5.1.1) and tried to run my iOS app on iPhone 6 simulator for the first time. It builds and runs, but I cannot change its settings

Answer 1

This is a known bug in iOS 8.0 in the simulator. The only workaround at this time is to set the preferences from the command line using the defaults command line tool.

defaults write ˜/Library/Developer/CoreSimulator/Devices//data/Containers/Data/Application//Library/Preferences/...

You also need to find the relevant UDID.
