What is GraphQL?

GraphQL is a query language for APIs that allows clients to request exactly the data they need in a single request. iOS apps interact with GraphQL APIs using libraries like Apollo iOS. GraphQL reduces over-fetching and under-fetching of data, making it efficient for mobile clients on limited bandwidth.
