YGSONEncoder

A reimplementation of JSONEncoder to have sortedKeys on pre-iOS 11 (not based on JSONSerialization).

Code largely inspired by:

• apple/swift for snakeCaseConversion
• apple/swift-corelibs-foundation for pretty printing

Current features

• DateEncodingStrategy
• DataEncodingStrategy
• OutputFormatting
• KeyEncodingStrategy
• JSONEncoder.NonConformingFloatEncodingStrategy
• Class inheritance encoding

Usage

struct TestUnsortedStruct: Codable {
       let z: String
       let b: String
       let r: String
       let c: String
}

let element = TestUnsortedStruct(z: "1", b: "2", r: "3", c: "4")
let encoder = YGSONEncoder()
encoder.outputFormatting = [.sortedKeys]

do {
    let data = try encoder.encode(element)
    } catch let error {
        print("Error: \(error)")
}
