I can't seem to be able to simulate locations using Xcode 5 with iOS 7 devices or the iOS 7 simulator. However when running the same app on an iOS 6 device it works fine. Is there any workaround for this or has the GPX format required changed?
The best workaround I've found is to set the default location on the scheme under the options tab. The biggest downside is that you can't change the location after you set the first one.
