Ignite

Today’s lecture was designed around learning how to use JSON apis and we made a sample app that did as such. I’ve done this kind of thing before, but not extensively…

Vwhoosh

But, in my limited experience, somehow I had no idea that there was a free database out there full of Star Wars data! That’s right, my school is so cool we made an app in class to search a Star Wars database for characters! The site the database is hosted on is called SWAPI. (Naturally, as I’m writing this, the site went down. It already happened, so I can’t even take credit for it with my massive viewer numbers!)

Clash!

I made an incomplete model for a character, if anyone is interested at all.

struct Person: Decodable {
    let name: String
    let gender: Gender
    let birthYear: String
    let height: Int
    let mass: Int
    let hairColor: String
    let skinColor: String
    let eyeColor: String

    enum Gender: String {
        case male
        case female
        case na
        static func genderForString(_ string: String) -> Gender {
            let lc = string.lowercased()
            switch lc {
            case "male":
                return .male
            case "female":
                return .female
            default:
                return .na
            }
        }
    }
}

extension Person {
    enum CodingKeys: String, CodingKey {
        case name
        case gender
        case birthYear = "birth_year"
        case height
        case mass
        case hairColor = "hair_color"
        case skinColor = "skin_color"
        case eyeColor = "eye_color"
    }

    init(from decoder: Decoder) throws {
        let container = try decoder.container(keyedBy: CodingKeys.self)

        name = try container.decode(String.self, forKey: .name)
        let genderStr = try container.decode(String.self, forKey: .gender)
        gender = Gender.genderForString(genderStr)
        birthYear = try container.decode(String.self, forKey: .birthYear)
        let heightStr = try container.decode(String.self, forKey: .height)
        height = Int(heightStr) ?? 0
        let massStr = try container.decode(String.self, forKey: .mass)
        mass = Int(massStr) ?? 0
        hairColor = try container.decode(String.self, forKey: .hairColor)
        skinColor = try container.decode(String.self, forKey: .skinColor)
        eyeColor = try container.decode(String.self, forKey: .eyeColor)
    }
}

struct PersonSearch: Decodable {
    let results: [Person]
}

Hummmmmmm

If that’s not enough for you, I suppose you can have the rest of the project. It’s not much, but it’s fun!
