SwiftGoingFaster by Precompiled Bridging Headers

Faster Mix-and-Match Builds with Precompiled Bridging Headers

apple_swift_logo

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]

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

Firebase Remote Config
Firebase Remote Config

Basic setup is to create project at firebase console.
Firebase Console
Firebase Console – Follow the steps to create a project

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

  1. Installation
    Update your project with required cocoapods

    Run pod install from terminal and open the created .xcworkspace file.
  2. Configure Firebase Module
    Just import firebase module and apply configure method. It will configure by itself by using GoogleService-Info.plist.
  3. Configure remote config
    Create Remote Config object, as shown in the following example:

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

    FireSwiftRemoteConfigDefaults.plist with sampleURL key:

    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:

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

Steps to use Legacy Swift in Xcode 8

Xcode Swift iOS10

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.

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.

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.

Response should be like

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

#Like #Share #React 🙂 😛 😀

How to work with IBDesignable and IBInspectable in Swift Language?

IBDesignable with Storyboard
IBDesignable with Storyboard

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

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.

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.
