In order for these scripts to work adb must be reachable in the shell. If it's not then add adb location to PATH. On Windows you may also place adb.exe, AdbWinApi.dll, AdbWinUsbApi.dll to the same folder with the script.

On MacOS to open the script with double click it should be saved with .command extension.

Example:

rotorgames

using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Collections.Specialized;
using System.ComponentModel;
using System.Linq;

namespace Example
{
    public class SmartObservableCollection<T> : ObservableCollection<T>
    {

To Implement swipe down to close behavior, we should attach the behavior to a view.

In XAML

<ContentView x:Name="ViewToMove">
   <ContentView.Behaviors>
     <behavior:SwipeDownToClosePopupPage  CloseAction="ClosePage" ParentView="{x:Reference ViewToMove}"/>  
   </ContentView.Behaviors>
</ContentView>

Note

Apple will reject apps that are using private url schemes (Ugh, Apple....) if they are pretty much obvius. Some apps are rejected and others are not, so, be aware of this issue before implementing any of those URL's in your app as a feature.

Updates

• [UPDATE 4] iOS 10 update: apparently settings now can be reached using App-Pref instead of prefs
• [UPDATE 3] For now you just can use url schemes to open your apps's settings with Swift 3.0 (Xcode 8). I'll keep you informed when OS preferences can be reached
• [UPDATE 2] The openURL() method of UIApplication is now deprecated. You should use application(_:open:options:) instead
• [UPDATE 1] Not yet tested in iOS 10. It will fail because of policies changes in URL scheme handling.
