Realm-cocoa: Getting compile errors when running project with Xcode 8.2.1 / Realm 2.4.1 / Cocoapods 1.2.0

[thomasgravina]

Goals

I want to be able to use Realm in a iOS Swift 3.0.2 project.

Expected Results

For the project to compile and run.

Actual Results

Getting error messages at compile time:

Genre.swift:23:1: 'required' initializer 'init()' must be provided by subclass of 'Object'

Genre.swift:23:1: 'required' initializer 'init(realm:schema:)' must be provided by subclass of 'Object'

Genre.swift:23:1: 'required' initializer 'init(value:schema:)' must be provided by subclass of 'Object'

Steps to Reproduce

• Followed Realm tutorial on how to get started:
• Enriched Podfile
• Ran pod install
• Open .xcworspace project
• Ran the project

Code Sample

Podfile

platform :ios, '8.0'
use_frameworks!

pod 'Fabric'
pod 'Crashlytics'
pod 'RealmSwift'

target 'MyProject' do
source 'https://github.com/CocoaPods/Specs.git'
pod 'XCGLogger', '~> 4.0.0'
end

target 'MyProject Tests' do

end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '3.0.2'
    end
  end
end

Genre.swift

import Foundation
import RealmSwift

class Genre: Object {

    // MARK: Properties
    dynamic var id: Int
    dynamic var name: String

    init?(id: Int, name: String) {
        self.id = id
        self.name = name
        super.init()
    }

    override class func primaryKey() -> String? {
        return "id"
    }

    override class func indexedProperties() -> [String] {
        return ["name"]
    }
}

Hi! Thanks for reaching out to us, and sorry you're seeing this error.

To fix this error, you can set initial values on your properties, and then make your initializer a convenience initializer:

class Genre: Object {
    dynamic var id: Int = 0
    dynamic var name: String = ""

    convenience init(id: Int, name: String) {
        self.init()
        self.id = id
        self.name = name
    }
    // ...
}

Hope that helps, let us know if you have any other questions! Thanks for using Realm!
