v2.1.1 to v2.2.0

Runtime compatibility

Appfigurate app 2.2.0 is backwardly runtime compatible with apps and app extensions linked against Appfigurate library 2.1.1.

Source compatibility

Appfigurate 2.2.0 is mostly source compatible with 2.1.1. Some minor changes are required:

Info.plist changes

• Remove the APLConfigurationClass key/value pair. In order to improve reliability and startup time of your app, Appfigurate Library no longer uses the APLConfigurationClass key/value pair to instantiate your APLConfiguration subclass. Instead it calls the APLConfigurationClass function that you implement (see Objective-C/Swift changes below):

Objective-C/Swift changes

• Add a new C function APLConfigurationClass to the bottom of your APLConfiguration subclass:

Objective-C example

Class APLConfigurationClass(void) {
    return [ExampleConfiguration class];
}

Swift example

@_cdecl("APLConfigurationClass")
func APLConfigurationClass() -> AnyClass {
    return ExampleConfiguration.self
}

Upgrading your APLConfiguration subclass from Objective-C ‣ Swift

One of the key features of Appfigurate 2.2.0 is support for Swift 5.3 using property wrappers. It is relatively simple to upgrade your APLConfiguration subclass from Objective-C to Swift:

Output Swift implementation

Using Appfigurate tap ≡ ‣ App ‣ Output Implementation under the SWIFT LIBRARY INTEGRATION section. The output will be similar to the following:

import Foundation
import AppfigurateLibrary

@objcMembers class Configuration: APLConfiguration {

	@BoolProperty(description: "Log debug output to console", restart: false)
	var debugLogging: Bool

	@StringPropertyListEdit(regex: #"https://[\w\.-]+\.yourappserver.com/.*"#, description: "Application server url", restart: false, values: ["Dev":"https://dev.yourappserver.com/api", "Prod":"https://www.yourappserver.com/api"])
	var serverURL: String

	override func allowInvalidSignatures() -> Bool {
		return !ENCRYPTED()
	}

	override func publicKey() -> String {
		// 41 36 87 71 0D 05
		return "-----BEGIN PUBLIC KEY-----\n" +
			"MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA4TZnKfGeXttN7Rr3eiAZ\n" +
			"PMEPsZvbo7lgIpMh6OjgBsoqkJJP0yXXLtpqsBCv8vm7RYqCn5+yfkiCQiXvkJBz\n" +
			"FSKmLF9EPR9l1H+32Id82dDuseD70D66puPUHjciEgmU18DpW2NVvTAykMwTEsiR\n" +
			"0h/ExBEhUe75qtwlVno8cMFbEfVtiGbKECvWIr122ED71T0Jt2Bcxqx1a7c1hPIV\n" +
			"RwLxIfWfE0+2rB9nJVPBgsTVPywibDvjio82FousyMDmvkAbMq5iyuyvJ0+5bATz\n" +
			"o12GEt5lSiQlCMzfmkWYBROMDCh27qGFVVo1XAUCVsMfsW9n4iQcoLAdUp/LI3B3\n" +
			"ywIDAQAB\n" +
			"-----END PUBLIC KEY-----\n"
	}

	override func reset() {
		debugLogging = true
		serverURL = "https://www.yourappserver.com/api"
	}

}

@_cdecl("APLConfigurationClass")
func APLConfigurationClass() -> AnyClass {
    return ExampleConfiguration.self
}

Delete the debugLogging and serverURL properties and port your Objective-C properties across one-by-one as per the following Macros ‣ Property wrappers section below.

Macros ‣ Property wrappers

Appfigurate's swift property wrappers are named the same as the Objective-C macros making it easy to port:

Objective-C macro	Swift property wrapper
BOOL_PROPERTY	@BoolProperty
STRING_PROPERTY_EDIT	@StringPropertyEdit
STRING_PROPERTY_LIST	@StringPropertyList
STRING_PROPERTY_LIST_EDIT	@StringPropertyListEdit
ENCRYPTED_STRING_PROPERTY_LIST_EDIT	@EncryptedStringPropertyListEdit
INT_PROPERTY_SLIDER	@IntPropertySlider
INT_PROPERTY_EDIT	@IntPropertyEdit
INT_PROPERTY_LIST	@IntPropertyList
INT_PROPERTY_LIST_EDIT	@IntPropertyListEdit
FLOAT_PROPERTY_SLIDER	@FloatPropertySlider
FLOAT_PROPERTY_EDIT	@FloatPropertyEdit
FLOAT_PROPERTY_LIST	@FloatPropertyList
FLOAT_PROPERTY_LIST_EDIT	@FloatPropertyListEdit
DOUBLE_PROPERTY_SLIDER	@DoublePropertySlider
DOUBLE_PROPERTY_EDIT	@DoublePropertyEdit
DOUBLE_PROPERTY_LIST	@DoublePropertyList
DOUBLE_PROPERTY_LIST_EDIT	@DoublePropertyListEdit
ACTION_METHOD	No Swift equivalent

Objective-C Example

@interface Configuration : APLConfiguration
@property(nonatomic, assign) BOOL logging;
@end

@implementation Configuration
BOOL_PROPERTY(logging, @"Enable debug logging to console", NO);
...

Swift Example

@objcMembers class Configuration: APLConfiguration {
    @BoolProperty(description: "Enable debug logging to console", restart: false)
    var logging: Bool
    ...

@objcMembers/@objc

You must either mark the entire APLConfiguration subclass with @objcMembers (recommended approach) or mark each configuration property individually with @objc. Omitting these markers will cause the properties to be unavailable for access by Appfigurate Library.

@objcMembers Example

@objcMembers class Configuration: APLConfiguration {
    @BoolProperty(description: "Enable debug logging to console", restart: false)
    var logging: Bool
    ...

@objc Example

class Configuration: APLConfiguration {
    @BoolProperty(description: "Enable debug logging to console", restart: false)
    @objc var logging: Bool
    ...
