Building Your App SDK w/ Swift:A Soup to Nuts GuideJordan Yaker@jordanyaker
Supportify.io
State Of The Product (Spring 2015)•Mature Product•Few Client Libraries•Not Many Customers
Coming Up With A Plan
Libraries Created•.NET Nuget Package•Ruby Gem•PHP Composer Package•WordPress Plugin
Time For iOS•Learn Objective-C• tryobjectivec.codeschool.com• raywenderlich.com/category/ios
•Build Base SDK•???
Get Some Swagger
API Specification Frameworks•RAML• raml.org
•API Blue-Print•apiblueprint.org
•Swagger•swagger.io
•Protocol Buffers•developers.google.com/protocol-buffers
Swagger Project•Swagger Specification•github.com/OAI/OpenAPI-Specification
•Swagger Editor•editor.swagger.io
•Swagger Codegen•github.com/swagger-api/swagger-codegen
Problems With That Swagger•Beware Of Authentication•Early Adopter Woes
Supportify Got Swagger (Fall 2015)•.NET Nuget Package•Ruby Gem•PHP Composer Package•Python Package•Java/Android Maven Package•Objective-C CocoaPod
supportify-ios (1.0.0.beta)•Objective-C•AFNetworking•Erased From History•That’s a good thing.
•“Sick code, bro. No really I think it’s contagious. I feel sick just from looking at it.”
Swift: A Modern Language That’s Not Objective-C Code
Time For iOS (Again)•Learn Objective-C•Build Base SDK•Learn Swift•Code School: Swift Live Part 1 / Part 2• raywenderlich.com/category/swift•github.com/raywenderlich/swift-style-guide•developer.apple.com/swift

Why Was The SDK Still Terrible?
“You’re telling me that this is going to save me time, but I have to jump through all of these
hoops to implement it? I’ve already got enough to do on a regular basis. F*ck that. Give me an easy to implement solution that
gives me no aggravation, man.”- Nate Bomberger

Here Comes A New Challenger:Clean Swift
The Clean Swift Design Pattern

•Configurators Wire Everything Together•Controllers Talk To The Router•Everything Else Talks To The “Next” Thing
The Benefits•Reduced Interdependencies•Component Isolation•Fine-Grained Exposure•Easier Inheritance•Easier Implementation
Oh Look, More Problems
I Got 99 Problems & Swagger Is One•No Passing Of Server Errors•No Parsing Of Server-Returned Error Objects•AlamoFire Demands Data With 200 Status •The API Wasn’t Using 204 Status Codes
The API Needed Some Tweaks•Tag And Category Filtering•CSV (“Tag 1, Tag 2, Tag 3”) •Rudimentary DSL (“Tag 1 AND (Tag 2 OR Tag
3)”)•The “Order” Parameter•…And The Tests Just Weren’t As Good We Thought
The Final Product
supportify-ios (3.1.2)
•Swagger-Based Proxy•API Client•Resource Models
•Global Configurator•Authentication•Global Filters
•Scene Components•Category List•Entry List•Entry•Search List
But Wait – We’re Still Not Done
What Makes For Good Docs?•Copy And Paste•Simple To Complex•Good Structure
