+title: 1Flow Swift Plugin
+---
+
+[1Flow](https://1flow.ai/?utm_source=segmentio&utm_medium=docs&utm_campaign=partners){:target="_blank"} is a leading in-app user survey and messaging platform for Mobile app and SaaS businesses.
+
+Using 1Flow, you can reach users _in-the-moment_ while they are interacting with your website or application to collect highly contextual user insights that help you improve your product offering and customer experience.
+
+## Getting started
+
+1. From the Segment web app, click **Catalog**, then search for **1Flow Mobile Plugin**.
+2. Click **Add Destination**.
+4. Select an existing Source to connect to 1Flow Mobile Plugin.
+5. Go to **1flow.ai > Settings > Project Settings**, copy the 1Flow project key, and paste it into the Destination Settings in Segment.
+6. Depending on the mobile source you’ve selected, include 1Flow's library by adding the following lines to your dependency configuration.
+
+## Adding the dependency
+
+### Through Xcode
+
+In the Xcode `File` menu, click `Add Packages`.  You'll see a dialog where you can search for Swift packages.  In the search field, enter the URL to this repository.
+```
+https://github.com/1Flow-Inc/segment-1flow-ios.git
+```
+
+
+You'll then have the option to pin to a version, or specific branch, as well as which project in your workspace to add it to. Once you've made your selections, click **Add Package**.  
+
+### Through Package.swift
+
+Open your Package.swift file and add the following to the `dependencies` section:
+
+```
+.package(
+            name: "Segment",
+            url: "https://github.com/1Flow-Inc/segment-1flow-ios.git",
+            from: "1.0.0"
+        ),
+```
+
+## Using the Plugin in your app
+
+Open the file where you set up and configure the Analytics-Swift library.  Add this plugin to the list of imports.
+
+```
+import Segment
+import SegmentOneFlow // <-- Add this line
+```
+
+Just under your Analytics-Swift library setup, call `analytics.add(plugin: ...)` to add an instance of the plugin to the Analytics timeline.
+
+```
+let analytics = Analytics(configuration: Configuration(writeKey: "<YOUR WRITE KEY>")
+                    .flushAt(3)
+                    .trackApplicationLifecycleEvents(true))
+analytics.add(plugin: OneFlowDestination())
+```
+
+## Identify
+If you're not familiar with the Segment Specs, take a look to understand what the [Identify method](/docs/connections/spec/identify/) does. An example call would look like:
+
+```swift
+analytics.identify(userId: "[email protected]", traits: [
+    "name": "Peter Gibbons",
+    "email": "[email protected]",
+    "mobile": 1234567890
+])
+```
+The Segment identify method is equivalent to `logUser` of 1Flow. `userId` will be `userID` and `traits` will be `userDetails`.
+
+## Track
+If you're not familiar with the Segment Specs, take a look to understand what the [Track method](/docs/connections/spec/track/) does. An example call would look like:
+
+```swift
+analytics.track(name: "ButtonClicked")
+```
+Any value passed in `name`, will be eventName and if you have passed any event property, then it will be event `parameters`.
+
+## Screen
+
+Send [Screen](/docs/connections/spec/screen) calls to record which mobile app screens users have viewed. For example:
+
+```swift
+analytics.screen(title: "Home")
+```
+
+Segment sends Screen calls to 1Flow as a `screen_[name]` event (or `screen_view` if a screen name isn't provided).

 Analytics Swift uses its timeline/plugin architecture to support sending data to bundled SDKs when a Cloud Mode connection is not possible. Destination Plugins are similar to traditional Device Mode integrations available in Analytics-iOS in that Segment makes calls directly to the destination tool’s API from the device. However, Destination Plugins are more customizable, giving you the ability to control and enrich your data at a much more granular level on the device itself.
