ManagedAppConfigLib

Overview

The purpose of ManagedAppConfigLib is to make it much easier to work with Apple’s Managed App Configuration by providing a class that manages access to it, as well as some property wrappers for modern Swift usage.

Managed App Configuration is supported by Apple on iOS 7+, macOS 11+, and tvOS 10.2+.

Basic Usage

You will need to import ManagedAppConfigLib in each Swift file you wish to use it.

SwiftUI Property Wrapper

Functions much like the @AppStorage property wrapper built in to SwiftUI. Provides a type-safe read-only property that keeps itself current with any changes in the AppConfig value, and causes a SwiftUI redraw when it’s value changes.

// If AppConfig "title" doesn't exist or is not a string, will have the value "Default title".
@AppConfig("title") var title = "Default title"
// If AppConfig "featureEnabled" doesn't exist or is not a boolean, will have the value `false`.
@AppConfig("featureEnabled") var isEnabled: Bool = false
// If AppConfig "orgColor" doesn't exist or is not a string, this will be nil.
@AppConfig("orgColor") var organizationHexColor: String?

Non-SwiftUI Property Wrapper

Functions much like the @AppConfig property wrapper except that it does not require SwiftUI. Provides a read-only property that keeps itself current with any changes in the AppConfig value. This is useful for UIKit or AppKit code or simple Foundation code in models or cli tools.

@AppConfigPlain("title") var title = "Default title"
@AppConfigPlain("featureEnabled") var isEnabled: Bool = false
@AppConfigPlain("orgColor") var organizationHexColor: String?

Simple functional use

• Retrieve a Managed App Configuration value

  if let deviceId = ManagedAppConfig.shared.getConfigValue(forKey: "deviceId") as? String {
    print(deviceId)
  }

• Register a closure to be executed when Managed App Configuration changes ```swift let myClosure = { (configDict: [String: Any?]) -> Void in print(“Managed App Configuration changed”) } ManagedAppConfig.shared.addAppConfigChangedHook(myClosure)

* Place a value into Managed App Feedback
```swift
let numberOfErrors = 0
ManagedAppConfig.shared.updateValue(numberOfErrors, forKey: "errorCount")
