iOS SwiftUI Combine Template

A template repo for getting setup quickly with an iOS project using the SwiftUI and Combine frameworks.

This template repo was built off of the original DM-iOS-Template

This project is managed through a Github project board. The board for this project is: here.

This project has been built along side a backend repo. It is a Rails6Api. Both are built around the concept of "Creations", a generic or duck-type model in the vein of "todos" or "widgets". It is to hold and show things that people "create".

We have added some basic structure to this application we deem useful such as:

• NavigationViews, NavigationLinks, and Lists in SwiftUI
• use of publisher/observer pattern in SwiftUI
• MVVM as an ObserverableObject
• Testing of MVVM publishing
• Wrapping networking layer publisher with json decoding of generics

Configuration - How to add environment variables?

1. Add the vairable in the .xcconfig files, found in the Configs/ folder.

API_URL = http:/$()/localhost:3000

2. Add the variable in Info.plist.

<key>API_URL</key>
<string>$(API_URL)</string>

3. Add the variable in Config.swift.

• Add it to the Keys.Plist enum

enum Keys {
    enum Plist {
      static let apiURL = "API_URL"
    }
  }

• Add the getter

static let apiUrl: URL = {
    guard let apiUrlstring = Config.infoDictionary[Keys.Plist.apiURL] as? String else {
      fatalError("\(Keys.Plist.apiURL) not set in plist for this environment")
    }
    guard let url = URL(string: apiUrlstring) else {
      fatalError("\(Keys.Plist.apiURL) is invalid")
    }
    return url
}()

Configuration - Secure your environment variables

Use the examples to set up your environments, but don't add them to your version control system. Since they might contain secrets, you want to keep them in a secure location (like 1Password). They can then be shared securely amongst developers.

Architecture

• Application currently makes use of SwiftUI NavigationView and NavigationLink for navigation (A coordinator pattern may be added back in)
• Configuration is set up for Development, Staging and Production.
• MVVM is implemented as an example.
