SourceryTemplates

This repository contains a collection of templates for Sourcery to help you with common issues you have to face during your Swift development by generating code for you.

Available Templates

• DecodableDecorated

DecodableDecorated

• Don't care about CodingKeys
• Don't care about writing the init(from decoder: Decoder) initializer
• Don't care about properties being optional or not
• Don't care about new properties being added or removed without modifing the corresponding Decodable code

When you use the Codable protocol in Swift and want to use at least one different key from your API (e.g. fill the text property of your class or struct with the content of description that comes from a JSON API), you have to completely code your own set of CodingKeys and reconstruct the init(from decoder: Decoder). This is all taken care of by this template.

It is decorating, so the code will be placed directly into YOUR code with corresponding markup used by Sourcery. To add a mapping key, simply use the key annotation.

e.g.:

Input

classWithAnotherKey:Codable{vartitle:String?varid:Int
// sourcery: key = "description"
vartext:String}classNormalCodable:Codable{vartitle:Stringvarcreated:Date}

Output

classWithAnotherKey:Codable{vartitle:String?varid:Int
// sourcery: key = "description"
vartext:String
// sourcery:inline:auto:WithAnotherKey.DecodableDecorated
enumCodingKey:String,CodingKey{case title case id case text ="description"}requiredinit(from decoder:Decoder)throws{letvalues=try decoder.container(keyedBy:CodingKeys.self)self.title =try values.decodeIfPresent(String.self, forKey:.title)self.id =try values.decode(Int.self, forKey:.id)self.text =try values.decode(String.self, forKey:.text)}
// sourcery:end
}classNormalCodable:Codable{vartitle:Stringvarcreated:Date}

Note that the NormalCodable didn't get any code as it is not required
