SwiftGoingFaster by Precompiled Bridging Headers

February 7, 2021January 31, 2017 by Ashish Kakkad

Faster Mix-and-Match Builds with Precompiled Bridging Headers

PROBLEM :
Every time a Swift file in a mixed-language target is compiled, the Swift compiler parses the project’s bridging header in order to make Objective-C code visible to Swift code. When the bridging header is large and the Swift compiler runs many times – as in a debug configuration – the cost of repeatedly parsing the bridging header can be a substantial part of the overall build time.

In Swift 3.1, you can reduced debug build time by 30% by using the new -enable-bridging-pch Swift flag for this issue. This mode is still experimental and must be manually enabled, but it will be enabled by default if developer feedback indicates it’s working well and providing significant speedup… so try it out!

Firebase Remote Config [Swift]

February 7, 2021November 25, 2016 by Ashish Kakkad

Firebase Remote Config is used to change the application behavior without publishing update of application.

Basic setup is to create project at firebase console.

I am adding a video here to setup the firebase remote config.

Add core firebase to your project

Follow the steps available at : Add Firebase to your iOS Project

Steps to add remote config to your app

Installation
Update your project with required cocoapods

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'
target 'FireSwiftRemoteConfig' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!
  # Pods for FireSwiftRemoteConfig
    pod 'Firebase/Core'
    pod 'Firebase/RemoteConfig'
end

# Uncomment the next line to define a global platform for your project

platform :ios, '9.0'

target 'FireSwiftRemoteConfig' do

# Comment the next line if you're not using Swift and don't want to use dynamic frameworks

use_frameworks!

# Pods for FireSwiftRemoteConfig

pod 'Firebase/Core'

pod 'Firebase/RemoteConfig'

end

Run pod install from terminal and open the created .xcworkspace file.

Configure Firebase Module
Just import firebase module and apply configure method. It will configure by itself by using GoogleService-Info.plist.

import UIKit
import Firebase
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Firebase Configuration
        FIRApp.configure()
        return true
    }
}

import UIKit

import Firebase

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

// Firebase Configuration

FIRApp.configure()

return true

}

Configure remote config
Create Remote Config object, as shown in the following example:

var remoteConfig: FIRRemoteConfig!
override func viewDidLoad() {
    super.viewDidLoad()
    remoteConfig = FIRRemoteConfig.remoteConfig()
}

var remoteConfig: FIRRemoteConfig!

override func viewDidLoad() {

super.viewDidLoad()

remoteConfig = FIRRemoteConfig.remoteConfig()

}

Create an plist file for default values of configuration and set it to remote config:

let remoteConfigSettings = FIRRemoteConfigSettings(developerModeEnabled: true)
remoteConfig.configSettings = remoteConfigSettings!
remoteConfig.setDefaultsFromPlistFileName("FireSwiftRemoteConfigDefaults")

let remoteConfigSettings = FIRRemoteConfigSettings(developerModeEnabled: true)

remoteConfig.configSettings = remoteConfigSettings!

remoteConfig.setDefaultsFromPlistFileName("FireSwiftRemoteConfigDefaults")

FireSwiftRemoteConfigDefaults.plist with sampleURL key:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>sampleURL</key>
	<string>http://google.com</string>
</dict>
</plist>

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<dict>

<key>sampleURL</key>

<string>http://google.com</string>

</dict>

</plist>

Use current default key from your defaults set on plist file and send fetch request in remote config to get the configuration keys set on the firebase console:

func fetchConfiguration() {
    lblResult.text = remoteConfig[sampleURLConfigKey].stringValue
    var expirationDuration = 3600
    if remoteConfig.configSettings.isDeveloperModeEnabled {
        expirationDuration = 0
    }
    remoteConfig.fetch(withExpirationDuration: TimeInterval(expirationDuration)) { (status, error) -> Void in
        if status == .success {
            print("Config fetched!")
            self.remoteConfig.activateFetched()
        } else {
            print("Config not fetched")
            print("Error \(error!.localizedDescription)")
        }
        lblResult.text = remoteConfig[sampleURLConfigKey].stringValue
    }
}

func fetchConfiguration() {

lblResult.text = remoteConfig[sampleURLConfigKey].stringValue

var expirationDuration = 3600

if remoteConfig.configSettings.isDeveloperModeEnabled {

expirationDuration = 0

}

remoteConfig.fetch(withExpirationDuration: TimeInterval(expirationDuration)) { (status, error) -> Void in

if status == .success {

print("Config fetched!")

self.remoteConfig.activateFetched()

} else {

print("Config not fetched")

print("Error \(error!.localizedDescription)")

}

lblResult.text = remoteConfig[sampleURLConfigKey].stringValue

}

Note : If in developer mode cacheExpiration is set to 0 so each fetch will retrieve values from the server. The default expiration duration is 43200 (12 hours).

All Done.
Sample code available at Github. There are many other things with firebase, I will try give update in next tutorials.

Refined API Naming : Migrating to Swift 3!

February 7, 2021October 18, 2016 by Ashish Kakkad

Xcode 8.0 comes with a Swift Migrator tool that helps you migrate your project to Swift 3, or update it to work with Swift 2.3 and the new SDKs.

Push Notifications in iOS 10 [Swift]

February 7, 2021September 29, 2016 by Ashish Kakkad

The new framework called “UserNotifications” is introduced with iOS 10 SDK. The UserNotifications framework (UserNotifications.framework) supports the delivery and handling of local and remote notifications.

So, Let see what we have to change to get the push notifications in iOS 10.

Steps to use Legacy Swift in Xcode 8

February 7, 2021September 21, 2016 by Ashish Kakkad

Xcode 8.0 is released with Swift 3 and Swift 2.3 compatibility.

If you already having a project with Swift 2.2 language support with Xcode 7.3.1 and you open the project in Xcode 8.0 then, you will be prompted for the migration assistant to do a migration pass. The assistant can also be invoked manually from the menu Edit -> Convert -> To Current Swift Syntax…

Use Swift 2.3 Modifies your project to enable the Use Legacy Swift build setting and provides source changes to be able to build against the new SDKs.
Use Swift 3 This is recommended. You will get source changes to be able to build your project using Swift 3 and take advantage of all the new features in Xcode 8.0.

If you want to work with new project and you want to work with Legacy code (Swift 2.3) or 3.0 then you can do settings from build settings as follows :

Build Settings - Swift Legacy Code — Build Settings – Swift Legacy Code

Default Setting is No (Swift 3). But if you want to do legacy code (Swift 2.3) then you have to select Yes (Swift 2.3).
Make sure you do this setting by starting of new project because many methods will change.
For Example :
Swift 3 Code
[code language=”obj-c”]
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
return true
}
[/code]
Swift 2.3 Code
[code language=”obj-c”]
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
return true
}
[/code]
As per my opinion Swift 3 is recommended.
Happy Coding 🙂

Get Reactions from Timeline Post via Facebook Graph API – Swift – iOS

February 7, 2021April 13, 2016 by Ashish Kakkad

New version of SDK is 4.16.x(Swift) and Graph API Version is 2.8.
With the Graph API 2.6 Facebook has given support to fetch (read only) the Reactions on Timeline Posts.

Post is updated for iOS 10 and Swift 3

API documentation is available here.

Let’s learn how to get reactions from the post

Install pods

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'
target 'FBSwiftLogin' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!
  # Pods for FBSwiftLogin
    pod 'FacebookCore'
    pod 'FacebookLogin'
end

# Uncomment the next line to define a global platform for your project

platform :ios, '9.0'

target 'FBSwiftLogin' do

# Comment the next line if you're not using Swift and don't want to use dynamic frameworks

use_frameworks!

# Pods for FBSwiftLogin

pod 'FacebookCore'

pod 'FacebookLogin'

end

Login with Facebook

I have already written a tutorial on Facebook Login.

Get Facebook Posts via Graph API

We can get the Facebook post via graph API : /me/posts for that we have to add user_posts permission with login.

func getFacebookUserPosts() {
    FBSDKGraphRequest(graphPath: "/me/posts", parameters: nil, httpMethod: "GET").start(completionHandler: { (connection, result, error) in
        if (error == nil){
            print(result)
        }
    })
}

func getFacebookUserPosts() {

FBSDKGraphRequest(graphPath: "/me/posts", parameters: nil, httpMethod: "GET").start(completionHandler: { (connection, result, error) in

if (error == nil){

print(result)

}

})

}

Get Reactions from one of the Post

We can get the Facebook post reactions via graph API : /{post-id}/reactions. We have to pass parameters like fields and summary as described in getReactions function.
Note : Here I am writing sample for only first post.

func getFacebookUserPosts() {
    var strGraphPath : String = ""
    FBSDKGraphRequest(graphPath: "/me/posts", parameters: nil, httpMethod: "GET").start(completionHandler: { (connection, result, error) in
        if (error == nil){
            print(result)
            let data = (result as! [String : Any])["data"] as! [[String : Any]]
            if(data.count > 0) {
                let strId = data[0]["id"] as! String
                strGraphPath = "/"+strId+"/reactions"
                self.getReactions(strGraphPath)
            }
        }
    })
}
func getReactions(_ strGraphPath:String) {
    FBSDKGraphRequest(graphPath: strGraphPath, parameters: ["fields":"id, name, type", "summary":"total_count, viewer_reaction"], httpMethod: "GET").start(completionHandler: { (connection, result, error) in
        if (error == nil){
            print(result)
        }
    })
}

func getFacebookUserPosts() {

var strGraphPath : String = ""

FBSDKGraphRequest(graphPath: "/me/posts", parameters: nil, httpMethod: "GET").start(completionHandler: { (connection, result, error) in

if (error == nil){

print(result)

let data = (result as! [String : Any])["data"] as! [[String : Any]]

if(data.count > 0) {

let strId = data[0]["id"] as! String

strGraphPath = "/"+strId+"/reactions"

self.getReactions(strGraphPath)

}

})

}

func getReactions(_ strGraphPath:String) {

FBSDKGraphRequest(graphPath: strGraphPath, parameters: ["fields":"id, name, type", "summary":"total_count, viewer_reaction"], httpMethod: "GET").start(completionHandler: { (connection, result, error) in

if (error == nil){

print(result)

}

})

}

Response should be like

Type of reactions : NONE, LIKE, LOVE, WOW, HAHA, SAD, ANGRY

{
    data =     (
        {
            id = ACCOUNT_ID;
            name = "NAME";
            type = HAHA;
        },
        {
            id = ACCOUNT_ID;
            name = "NAME";
            type = LIKE;
        }
    );
    paging =     {
        cursors =         {
            after = REFERENCE_ID;
            before = REFERENCE_ID;
        };
        next = "NEXT_REFERENCE_LINK";
    };
    summary =     {
        "total_count" = 56;
        "viewer_reaction" = NONE;
    };
}

{

data = (

{

id = ACCOUNT_ID;

name = "NAME";

type = HAHA;

{

id = ACCOUNT_ID;

name = "NAME";

type = LIKE;

}

);

paging = {

cursors = {

after = REFERENCE_ID;

before = REFERENCE_ID;

};

next = "NEXT_REFERENCE_LINK";

};

summary = {

"total_count" = 56;

"viewer_reaction" = NONE;

};

}

#Like #Share #React 🙂 😛 😀

How to create a wrapper for Alamofire and SwiftyJSON? Swift – iOS

February 7, 2021March 9, 2016 by Ashish Kakkad

This blogpost updated with Swift 3 – Xcode 8 – iOS 10 – Alamofire 4.0

I have posted a basic tutorial about Alamofire and SwiftyJSON How to use Alamofire and SwiftyJSON with Swift?
And some day before we have learned about Use of Blocks(Closures) or Completion Handlers with Function in Swift – iOS
Let’s combine both the topics to make a WRAPPER of Alamofire and SwiftyJSON.

How to use Alamofire and SwiftyJSON with Swift? – Swift 3 – iOS 10 – Xcode 8

February 7, 2021October 6, 2015 by Ashish Kakkad

Alamofire is an HTTP networking library written in Swift.
SwiftyJSON makes it easy to deal with JSON data in Swift.

How to work with IBDesignable and IBInspectable in Swift Language?

February 7, 2021August 8, 2015 by Ashish Kakkad

How to use the @IBDesignable and @IBInspectable?

By giving you a simple example that we can not change the corner radius from the design view. We have to change it run time. If you want to make possible it with design time then you can use the @IBDesignable and @IBInspectable.

So, We are taking an example as IBButtonExtender for this the functionality

Border Color
Border Width
Corner Radius

Create an Custom Class for UIButton with @IBDesignable

@IBDesignable
class ButtonExtender: UIButton {
}

@IBDesignable

class ButtonExtender: UIButton {

}

Create an @IBInspectable for Inspect the element. the Border Color property will be added to the list in the right panel when you create button with this class.

@IBInspectable var borderColor: UIColor = UIColor.white {
    didSet {
        layer.borderColor = borderColor.cgColor
    }
}

@IBInspectable var borderColor: UIColor = UIColor.white {

didSet {

layer.borderColor = borderColor.cgColor

}

Set Initialization functions and other @IBInspectable as above.
You can check the code for the ButtonExtender.swift

IBButtonExtender

Presenting the ButtonExtender for Border Color, Border Width and Corner Radius function with the @IBDesignable and @IBInspectable in the Swift Language.

By making some corner radius and colors, You will get neat and clean output.

Github

Find IBButtonExtender on github 🙂
Check other articles on Swift Language.
All suggestions are acceptable. Put it in the comments!
Happy Coding 🙂
