Aside from offering access to files on servers, Transmit also serves as a local file repository that can be accessed by other iOS apps.
Transmit iOS also takes full advantage of the "Extensibility" options bundled into iOS 8, especially the "Share" extension that allows apps to easily share content with other apps. When installed, Transmit iOS can be accessed in any share sheet in iOS, and used to save any type of file directly to an FTP, SFTP, WebDAV, or Amazon S3 server or to local storage within the app.
For example, selecting Transmit iOS from the Share sheet in Safari lets an HTML page be saved to a server. Selecting Transmit iOS in an app like Evernote or Byword will allow a text file to be uploaded, while selecting the upload option in a photo app like Snapseed lets users save a photo directly to their personal servers using Transmit iOS.
With share sheet support, uploading a file to a server via Transmit iOS is as easy as uploading a file to a cloud storage service like Dropbox, and it works in quite a few third-party apps in addition to pre-installed apps.
Transmit iOS also serves as a "Document Picker," which means that it can be used in supported apps to open files stored directly off of a server. For instance, a Pages document stored on a server can be opened directly in the Pages app on iOS through Transmit iOS, and any changes made in iOS to that document will be saved to the original file in Transmit iOS.
Transmit iOS, like Transmit for Mac, is a full featured file management app. Users can connect to multiple servers, save favorite servers, upload files using drag and drop, delete content, move content, duplicate files, and easily transition files between local storage and an available server. The app's local storage option also allows it to store documents from other apps directly on the device.
Transmit iOS includes support for Touch ID, allowing users to secure the app with a fingerprint. A passcode lock is also available on devices that do not have access to Touch ID, ensuring that all content remains safe and access to servers is restricted.
As can be seen in Transmit iOS, iOS 8 is going to enable a slew of useful features that have not previously been possible with iOS, and thus far, we're only scratching the surface of what developers are going to bring to the operating system with the new APIs.
Panic plans to release Transmit for iOS 8 after iOS 8 becomes available to the public on September 17.
