+On iOS you'll need to add the following entry to your Info.plist file (located under ios/Runner) in order to access the device's location. Simply open your Info.plist file and add the following (make sure you update the description so it is meaningfull in the context of your App):
 
 ``` xml
 <key>NSLocationWhenInUseUsageDescription</key>
 <string>This app needs access to location when open.</string>
-<key>NSLocationAlwaysUsageDescription</key>
-<string>This app needs access to location when in the background.</string>
 ```
 
-If you would like to receive updates when your App is in the background, you'll also need to add the Background Modes capability to your XCode project (Project > Signing and Capabilities > "+ Capability" button) and select Location Updates. Be careful with this, you will need to explain in detail to Apple why your App needs this when submitting your App to the AppStore. If Apple isn't satisfied with the explanation your App will be rejected.
+If you don't need to receive updates when your app is in the background, then add a compiler flag as follows: in XCode, click on Pods, choose the Target 'geolocator_apple', choose Build Settings, in the search box look for 'Preprocessor Macros' then add the `BYPASS_PERMISSION_LOCATION_ALWAYS=1` flag.
+Setting this flag prevents your app from requiring the `NSLocationAlwaysAndWhenInUseUsageDescription` entry in Info.plist, and avoids questions from Apple when submitting your app. 
+
+You can also have this flag be set automatically by adding to the `Podfile` for your application:
+```agsl
+post_install do |installer|
+  installer.pods_project.targets.each do |target|
+    if target.name == "geolocator_apple"
+      target.build_configurations.each do |config|
+        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)', 'BYPASS_PERMISSION_LOCATION_ALWAYS=1']
+      end
+    end
+  end
+end
+```
+
+If you do want to receive updates when your App is in the background (or if you don't bypass the permission request as described above) then you'll need to:
+* Add the Background Modes capability to your XCode project (Project > Signing and Capabilities > "+ Capability" button) and select Location Updates. Be careful with this, you will need to explain in detail to Apple why your App needs this when submitting your App to the AppStore. If Apple isn't satisfied with the explanation your App will be rejected.
+* Add an `NSLocationAlwaysAndWhenInUseUsageDescription` entry to your Info.plist (use `NSLocationAlwaysUsageDescription` if you're targeting iOS <11.0) 
 
 When using the `requestTemporaryFullAccuracy({purposeKey: "YourPurposeKey"})` method, a dictionary should be added to the Info.plist file.

+* Adds option to bypass the request for permission to update location in the background (which can attract scrutiny from Apple upon app submission). To bypass, set the preprocessor macro `BYPASS_PERMISSION_LOCATION_ALWAYS` to 1 in XCode

 * Previously the plugin filtered out negative values for heading and/or heading accuracy. Now the plugin is returning the heading and/or the heading accuracy even if the they have a negative value (invalid), so that the developer can use it and decide what to do with it.
