What does a SiriKit developer do?
A SiriKit developer builds app extensions that let iOS and watchOS applications respond to voice commands through Appleโs virtual assistant. This role focuses on the Intents and IntentsUI frameworks to bridge user speech with specific app functions. The work requires defining how the system interprets requests and designing the visual interface that appears in Siri or Maps after a request completes. You translate standard voice interactions into executable code within the Apple ecosystem.
- Create and configure Intents App Extension targets in Xcode to handle specific user requests. You define intent definitions that map spoken phrases to app actions, such as creating a note or adding an item to a list. This process involves writing handler classes that parse parameters from the userโs voice input and execute the corresponding logic within the host application. Your code must accurately interpret the userโs goal and trigger the correct function without errors.
- Implement IntentsUI app extensions to display custom branding and content after Siri fulfills a request. You build view controllers that render specific information in the Siri interface or Apple Maps, ensuring the visual output matches the appโs design standards. This work requires you to connect the fulfilled intent data to your custom UI components so users see relevant results immediately. You control exactly what information appears on screen when the voice interaction ends.
- Test and verify Siri and Maps behavior to confirm intents resolve correctly across different scenarios. You run simulations to check if the system handles ambiguous inputs, missing parameters, or errors gracefully. This phase involves debugging the connection between the intent handler and the UI extension to ensure a smooth user experience. You adjust the configuration in Xcode to fix issues where the assistant fails to recognize the command or displays incorrect data.
How to hire a SiriKit developer on Upwork
Step 1: Post a job
Define your voice interface requirements clearly to attract specialists who understand Appleโs Intents framework. Use the Job Post Generator powered by Umaโข, Upwork's Mindful AI to draft a precise description in seconds. Describe your needs in a few sentences and Uma drafts a job post for the role. You can write a new post, update a saved draft, or reuse an existing post.
- Specify which SiriKit domains your app supports, such as lists or notes, so candidates know exactly which intent handlers they must build.
- List Xcode as a required tool and ask for experience configuring Intents App Extension targets within iOS or watchOS projects.
- Request examples of custom IntentsUI view controllers you have authored to display branded content in Siri or Maps interfaces.
Step 2: Evaluate candidates
Look for portfolios that demonstrate working voice integrations rather than just standard app screens. Uma can run instant video interviews and build shortlists with side-by-side comparisons to help you spot these technical signals quickly.
- Verify that the freelancer has implemented intent definition files and connected them to handler classes that successfully process user requests.
- Check for code samples showing how they manage state when Siri fulfills an intent without launching the main application interface.
- Confirm they have tested their extensions in real Siri interactions to ensure the system correctly recognizes and routes voice commands.
Step 3: Interview your top choices
Discuss specific technical challenges related to voice context and UI presentation during your conversations. Interviews can be scheduled and conducted within Upwork Messages with an immediate transcript and summary after each one.
- Ask how they handle errors when Siri cannot resolve a specific entity mentioned in a userโs voice command.
- Discuss their approach to designing lightweight IntentsUI extensions that load quickly and display relevant data without lag.
- Inquire about their process for debugging intent handling failures using Xcode console logs and device testing.
Step 4: Agree on scope and begin work
Set clear milestones for each intent domain you need implemented to track progress effectively. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.
- Define deliverables such as compiled Intents App Extensions that pass Appleโs validation checks for Siri integration.
- Require the freelancer to submit source code for all intent handlers and custom UI view controllers for your review.
- Establish a testing phase where you verify that Siri correctly triggers the appโs features and displays the expected interface.
