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.

Push Notifications in iOS 10 [Objective-C]

Push Notification iOS10
Push Notification iOS10

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 for implement code to handle push notifications in iOS 10

Import UserNotifications.framework in your AppDelegate file

Also add UNUserNotificationCenterDelegate.

Register for push notification

Before registration check the version of iOS and then based on versions do the code. For iOS 7 code was different, fro iOS 8 & 9 code was different and again for iOS 10 code is different.

As per my opinion you have to set the deployment target to iOS 8 or iOS 9 and later. For this you can check the adoption ratio of iOS in the devices.

Define constant for version check :

Add code in your did finish launching

Handling delegate methods for UserNotifications

You will be surprise that notification displayed when application in foreground too in iOS 10. As we know that in old versions we display alert or something else which will be look like notification comes in foreground.

There are two delegate methods need to be handled :

Add Push Notifications Entitlements

Go to your project target’s Capabilities tab and add Push Notifications Entitlements.

Push Notifications Entitlements

If it’s available in your certificates then it will enable directly else configure your profile with the certificates and you can enable this capability by that.

All Done!

Happy Coding ?

I have added sample code of objective-c on github with iOS 8, 9 and 10 support of push notification.
I have also posted about Push Notifications in iOS 10 [Swift].

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.

  • Speech
    Using the APIs in the Speech framework (Speech.framework), you can perform speech transcription of both real-time and recorded audio.
  • UserNotifications
    User Notifications framework (UserNotifications.framework), which supports the delivery and handling of local and remote notifications.
  • UserNotificationsUI
    User Notifications UI framework (UserNotificationsUI.framework) lets you customize the appearance of local and remote notifications when they appear on the user’s device.
  • VideoSubscriberAccount
    Video Subscriber Account framework (VideoSubscriberAccount.framework) to help apps that support authenticated streaming or authenticated video on demand (also known as TV Everywhere) authenticate with their cable or satellite TV provider.

Let’s learn how to get reactions from the post

Install pods

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.

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 πŸ™‚ πŸ˜› πŸ˜€
