The home directory is a unique location in the file system where your application and all its data are stored. You cannot choose or change the location of the home directory for your application; however iOS and Xamarin.
The Application Bundle is the folder that contains your application. It is distinguished from other folders by having the. Your application bundle contains your executable file and all the content files, images, etc. When you browse to your application bundle in Mac OS, it appears with a different icon than you see in other directories and the. To view the application bundle for the sample code, right-click on the project in Visual Studio for Mac and select Reveal in Finder.
Right-click on this icon and choose Show Package Contents to browse the contents of the Application Bundle directory. The contents appear just like the contents of a regular directory, as shown here:.
When your application is installed on a device, the operating system creates a home directory for your application, and creates a number of directories within the application root directory that are available for use. Since iOS 8, the user-accessible directories are NOT located within the application root, so you can't derive the paths for the application bundle from the user directories, or vice versa.
The earlier directory and file examples accessed the Documents directory. To write to another directory, you must construct a path using the ".. To allow the user to directly access files in your app, create a new boolean key in the Info. The app's Documents directory will now be available for browsing in the Files app.
In the Files app, navigate to On My iPhone and each app with shared files will be visible. The screenshots below show what the FileSystem sample app looks like:. These files can be accessed in iTunes when the device is connected and the user chooses the Apps tab. For example, the following screenshot shows the files in selected app shared via iTunes:. Users can only access the top-level items in this directory via iTunes. They cannot see the contents of any subdirectories although they can copy them to their computer or delete them.
Your application should take this into consideration and be resilient to destructive updates of the Documents folder. The sample code for this article creates both a file and a folder in the Documents folder in SampleCode. This screenshot shows how these appear in iTunes:. Refer to the Working with Images article for information about how to set icons for the application and for any custom document types you create.
If the UIFileSharingEnabled key is false or not present, then file sharing is, by default, disabled, and users will not be able to interact with your Documents directory. Backing up a large amount of data can take a long time. If you decide you need to back up any particular document or data, your application should use either use the Documents and Library folders. For transient data or files that can be easily retrieved from the network, use either the Caches or the tmp directory.
Although this policy was first introduced with iOS 5 which seems like a long time ago the guidance is still relevant to apps today.
Apple introduced iCloud Backup functionality with iOS 5. This feature provides the user with a complete backup in case their device is lost, stolen, or damaged. Because iCloud only provides 5 Gb of free space to each user and to avoid unnecessarily using bandwidth, Apple expects applications to only backup essential user-generated data.
To comply with the iOS Data Storage Guidelines, you should limit the amount of data that gets backed up by adhering to the following items:. When SetSkipBackupAttribute is true the file will not be backed-up, regardless of the directory it is stored in even the Documents directory. You can query the attribute using the GetSkipBackupAttribute method, and you can reset it by calling the SetSkipBackupAttribute method with false , like this:.
Since App Extensions run as part of a host application as opposed to their containing app , the sharing of data isn't automatic included so extra work is required. App Groups are the mechanism iOS uses to allow different apps to share data. If the applications have been properly configured with the correct entitlements and provisioning, they can access a shared directory outside of their normal iOS sandbox.
This value must also be referenced in each project's Entitlements. The iOS app and the extension can also share files using a common file path given they have been properly configured with the correct entitlements and provisioning :. If the Group Path returned is null , check the configuration of the entitlements and the provisioning profile and make sure that they are correct.
When a new version of your application is downloaded, iOS creates a new home directory and stores the new Application Bundle in it. This article showed that file system operations with Xamarin.

I needed to refresh the view in Organizer to see the files being placed there. If you know the specific name of the Cydia file, application or modification that you want to install on your iOS device, you can also tap the "Search" option from Cydia's home screen and enter the name of the file, application or modification.
Apple designed all of its iOS devices to be closed systems. This means Apple limits your ability to download and install apps and modifications to your device. Jailbreaking is a procedure that removes these limitations.
Jailbreaking an iOS device will automatically install the Cydia application. The procedure is legal, but jailbreaking will void the terms of your iOS device warranty. Since Matt McGew has provided content for on and offline businesses and publications.
