SDK Functions

Here's a list of all the functions and properties supported by the UserView iOS SDK.

All methods and properties are accessed through the Upscope.shared singleton.

Connection Management

Function	Description
`connect()`	Establishes a WebSocket connection to the servers.
`disconnect()`	Closes the connection and ends any active session.
`reset(reconnect: Bool = true)`	Resets the connection, clearing all stored identities and visitor data. Pass `false` to stay disconnected after reset.

Session Control

Function	Description
`stopSession()`	Ends the current screen sharing session.
`requestAgent()`	Signals that the visitor wants assistance from an agent.
`cancelAgentRequest()`	Cancels a pending agent request.
`getLookupCode()`	Requests a 4-digit lookup code from the server. Access the code via the `lookupCode` property or `lookupCodePublisher`.
`sendCustomMessage(_ message: String)`	Sends a custom text or JSON message to the agent (max 5000 characters).

State Properties

Property	Type	Description
`isConnected`	`Bool`	Whether the SDK is currently connected to the server.
`isInSession`	`Bool`	Whether a screen sharing session is currently active.
`connectionState`	`ConnectionState`	Current connection state (`.inactive`, `.connecting`, `.connected`, `.reconnecting`, `.error`).
`sessionState`	`SessionState`	Current session state (`.inactive`, `.pendingRequest`, `.active`, `.paused`, `.ended`).
`shortId`	`String?`	The visitor's unique short ID assigned by the server.
`lookupCode`	`String?`	The current 4-digit lookup code, if one has been generated.
`watchLink`	`URL?`	The full URL where agents can view the session (`https://upscope.com/w/{shortId}`).

Visitor Identification

You can set visitor identity either through direct property assignment or as a batch update.

Direct Properties

Upscope.shared.uniqueId = "user-123"
Upscope.shared.callName = "John Smith"
Upscope.shared.tags = ["#VIP"]
Upscope.shared.identities = ["John Smith", "john@example.com"]
Upscope.shared.metadata = ["plan": "enterprise", "region": "US"]

Batch Update

Use updateConnection() to update multiple fields at once:

Upscope.shared.updateConnection(
    uniqueId: "user-123",
    callName: "John Smith",
    tags: ["#VIP"],
    identities: ["John Smith", "john@example.com"],
    metadata: ["plan": "enterprise", "region": "US"]
)

Pass nil to keep an existing value unchanged. Only non-nil parameters are updated.

Reactive State (Combine)

Subscribe to state changes using Combine publishers:

import Combine

var cancellables = Set<AnyCancellable>()

// Connection state changes
Upscope.shared.connectionStatePublisher
    .sink { state in
        print("Connection: \(state)")
    }
    .store(in: &cancellables)

// Session state changes
Upscope.shared.sessionStatePublisher
    .sink { state in
        print("Session: \(state)")
    }
    .store(in: &cancellables)

// Short ID changes
Upscope.shared.shortIdPublisher
    .sink { shortId in
        print("Short ID: \(shortId ?? "none")")
    }
    .store(in: &cancellables)

// Lookup code changes
Upscope.shared.lookupCodePublisher
    .sink { code in
        print("Lookup code: \(code ?? "none")")
    }
    .store(in: &cancellables)

Masking

Hide sensitive content from agents during screen sharing.

Property/Function	Description
`maskSecureTextFields`	`Bool` — Automatically mask secure text fields. Default: `true`.
`addMaskedView(_ view: UIView)`	Register a UIKit view to be masked (hidden from agent).
`removeMaskedView(_ view: UIView)`	Unregister a masked view.
`allMaskedViews`	`[UIView]` — All currently masked views.

Example

// Mask a specific UIKit view
Upscope.shared.addMaskedView(creditCardField)

// Later, remove the mask
Upscope.shared.removeMaskedView(creditCardField)

// Disable automatic secure field masking
Upscope.shared.maskSecureTextFields = false
