3. Last year, my team decided to use GraphQL for our new feature 🏃
4. A new co-working space has opened in Shimokitazawa GraphQL is used in the new seat reservation featur e (Both iOS/Android)
5. GraphQL is used
6. GraphQL is used with apollo-ios
7. GraphQL is used with apollo-ios
8. About apollo-ios • The most popular open-sourced GraphQL client library for iOS
9. About apollo-ios • The most popular open-sourced GraphQL client library for iOS • Used in production by many companies around the world Github uses Apollo client potatotips #61
10. Apollo is great!
11. But it can be a hassle 🧐
12. • Explaining the hurdle I had in using Apollo Today, I will be..
13. Today, I will be.. • Explaining the hurdle I had in using Apollo • Looking at other alternatives
14. Today, I will be.. • Explaining the hurdle I had in using Apollo • Looking at other alternatives New to GraphQL? The details of GraphQL will not be covered here. However, you will probably able to understand this talk since I will be explaining about the implementation one by one 😉
15. Apollo iOS: Things I like about it
16. Apollo iOS: Things I like about it 1. Strong community 2. Guarantees compile time type safety
17. Apollo iOS: Things I like about it 1. Strong community 2. Guarantees compile time type safety
18. Apollo iOS has a strong community • Actively maintained by Apollo, which is a GraphQL focused company
19. • Actively maintained by Apollo, which is a GraphQL focused company Had seen an amazing work done in the community by the team, especially by Ellen 😭 Apollo iOS has a strong community
20. • Actively maintained by Apollo, which is a GraphQL focused company • Easy to fi nd resources about the library Apollo iOS has a strong community
21. Apollo iOS: Things I like about it 1. Strong community 2. Guarantees compile time type safety
22. Apollo iOS: Things I like about it 1. Strong community 2. Guarantees compile time type safety
23. What does this mean? 🤔
27. Queries are fl exible
30. Query-speci fi c nested structs will be generated ✅ Compile time safety
31. Queries are fl exible
32. Queries are fl exible name name name PersonCell CharacterList Tie a query to a view = View : Query or Fragment (Works well with SwiftUI)
33. name name name PersonCell CharacterList But this did not suit our case
34. name name name PersonCell CharacterList 👆 Check this out for the details
35. What’s the struggle? 🤔
36. • Dealing with nested structs can be a hassle especially when passing it to your domain layer Apollo iOS: The Struggle
37. Generated structs are nested based on a query Apollo iOS: The Struggle
38. Generated structs are nested based on a query The more query gets complicated, so does the structs. Apollo iOS: The Struggle
39. Generated structs are nested based on a query Generated structs does not conform to the Equatable protocol Apollo iOS: The Struggle 👆
40. I wish I could easily map to domain objects a little more…
41. It’s always an option • Not to use a client library and write your own client • Utilize Fragment
42. Any alternative?
43. Yes. graphql.org/code
44. Yes. Graphaello will not be covered here since it focuses on SwiftUI graphql.org/code 👉
45. Let’s look at SwiftGraphQL graphql.org/code 👉
46. Apollo iOS
47. Apollo iOS
48. Apollo iOS
49. SwiftGraphQL
50. SwiftGraphQL
51. SwiftGraphQL
52. SwiftGraphQL
53. SwiftGraphQL
54. Looks good for mapping to models!
55. Comparing apollo-ios and SwiftGraphQL
56. Comparing apollo-ios and SwiftGraphQL
57. Comparing apollo-ios and SwiftGraphQL
58. Summary • Mapping generated structs to domain objects can be a hassle • Other GraphQL clients can be your solution depending on your situation
59. developers.kankak.com I will post my update on the blog
60. Thank you!
