SettingsKit

A light-weight, extensible package for easily building pixel-perfect iOS settings screens in a pinch.

Installation

SettingsKit can be installed using Swift Package Manager. To get started...

1. Open your project in Xcode and navigate to File, Add Packages...
2. Search for https://github.com/sebjvidal/SettingsKit.git in the "Search or Enter Package URL" toolbar item
3. Choose SettingsKit
4. Click Add Package

Usage

In the following example, you'll learn how to build a settings screen with a single "General" group that has four child settings.

To begin, create an Array with a single SettingsKitSection object, parsing an Array of SettingsKitSetting to its setting initialiser.

import SettingsKit

let generalSections: [SettingsKitSection] = [
    SettingsKitSection(
        settings: [
            SettingsKitLabel(title: "A Label Cell", value: .userDefaults(key: "label")),
            SettingsKitToggle(title: "A Toggle Cell", value: .userDefaults(key: "toggle")),
            SettingsKitTextField(title: "A TextField Cell", value: .userDefaults(key: "textField")),
            SettingsKitStepper(title: "A Stepper Cell", value: .userDefaults(key: "stepper"), min: 0, max: 10)
        ]
    )
]

Each object conforming to the SettingsKitSetting protocol has a value property. This is an Enum case that can be a raw value, for example, .string("String"). Alternatively, this can be a UserDefaults key, for examlpe, .userDefaults(key: "Key").

Next, we'll build the SettingsKitGroup and, subsequently the SettingsKitGroup.Icon. Start by creating the SettingsKitGroup.Icon and populating its symbol, config and colour initialisers with a UIImage, UIImage.SymbolConfiguration and UIColor, respectively.

let generalIcon = SettingsKitGroup.Icon(
    symbol: UIImage(systemName: "gear"),
    config: UIImage.SymbolConfiguration(pointSize: 21),
    colour: UIColor.systemGray
)

Now, define a second Array of SettingsKitSection, passing an Array of SettingsKitSetting to its settings parameter. Populate the SettingsKitSetting Array with a single SettingsKitGroup object. Set the icon parameter to the generalIcon created above. Set the title parameter to "General". And set the children parameter to the generalSections array.

let rootSections: [SettingsKitSection] = [
    SettingsKitSection(
        settings: [
            SettingsKitGroup(icon: generalIcon, title: "General", children: generalSections)
        ]
    )
]

Finally, create the SettingsKitViewController, populating the sections parameter with the previously defined rootSections Array.

let viewController = SettingsKitViewController(sections: rootSections)

Additionally, the root SettingsKitViewController navigation elements can be customised as follows.

viewController.title = "SettingsKit"
viewController.navigationItem.largeTitleDisplayMode = .automatic
viewController.navigationController?.navigationBar.prefersLargeTitles = true

This is what your finished product should look like...

About

SettingsKit is built with UIKit, so you can customise the SettingsKitViewController as you would a UITableViewController.

Be careful when overriding the SettingsKitViewController tableView's delegate methods, as the following methods are used internally to make the package functional:

• numberOfSections(in:)
• tableView(_:titleForHeaderInSection:)
• tableView(_:titleForFooterInSection:)
• tableView(_:numberOfRowsInSection:)
• tableView(_:cellForRowAt:)
• tableView(_:heightForRowAt)
• tableView(_:shouldHighlightRowAt:)
• tableView(_:didSelectRowAt:)
