After speaking with the recruiter, I needed to pass a pair-programming round similar to Leetcode-style questions. After passing that, they scheduled the following interviews:

• One pair-programming round where I needed to solve a Leetcode-style problem
• One architecture and system design round
• One behavioural round
• One domain-specific pair-programming round

Create a project (SwiftUI/UIKit), import a Swift Package, and use it to fetch some JSON. Decode them and display it.

Two other questions required using a ListNode and a hash table.

As for the DS: we want to implement an app similar to FOO (where FOO was a famous app like Twitter).
