NSInternalInconsistencyException: 'Invalid parameter not satisfying: !stayUp || CLClientIsBackgroundable(internal->fClient)'

I've managed to solve this by doing these two things:

• added UIBackgroundModes 'location' to Info.plist
• added NSLocationAlwaysUsageDescription to Info.plist

As of iOS 11, keys are named:

• NSLocationAlwaysAndWhenInUseUsageDescription and NSLocationWhenInUseUsageDescription

Just select your app scheme and go to Capabilities as per my picture below everything should work fine.

Here's another solution if like me you want to use [CLLocationManager setAllowsBackgroundLocationUpdates:] in a separate project module / static library. You'll get this crash if the app using that module/library doesn't have the location background capability... I made the following method to make the call safe:

- (void) setAllowsBackgroundLocationUpdatesSafely
{
    NSArray* backgroundModes  = [[NSBundle mainBundle].infoDictionary objectForKey:@"UIBackgroundModes"];

    if(backgroundModes && [backgroundModes containsObject:@"location"]) {
        if([mLocationManager respondsToSelector:@selector(setAllowsBackgroundLocationUpdates:)]) {
            // We now have iOS9 and the right capabilities to set this:
            [mLocationManager setAllowsBackgroundLocationUpdates:YES];
        }
    }
}
