Many of the types are bridged to the Swift type like as (e.g., NSString being bridged to String).
Other Objective-C types are bridged to Swift are as follows :
CallKit The CallKit framework (CallKit.framework) lets VoIP apps integrate with the iPhone UI and give users a great experience. Use this framework to let users view and answer incoming VoIP calls on the lock screen and manage contacts from VoIP calls in the Phone appβs Favorites and Recents views.
Intents The Intents framework (Intents.framework) supports the handling of SiriKit interactions.
IntentsUI The Intents UI framework (IntentsUI.framework) supports the creation of an Intents UI extension, which is an optional app extension that displays custom content in the Siri or Maps interfaces.
Messages To develop an iMessage app, you use the APIs in the Messages framework (Messages.framework) and To create app extensions that interact with the Messages app, allowing users to send text, stickers, media files, and interactive messages.
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 userβs 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.

Now, Go with flow of technology, let’s learn something new… π
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.
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.
I was just going through the Swift document and I found that Swift allow to overload the operator just like as C++ Language. Objective-C doesn’t allow to overload the operator.
As swift document we can also say “Operator Functions”.
Let’s Overload ^ (XOR Operator) to make Power of the value
Function Prototype :
Declare function prototype with left hand side value and right and side value.
Swift
1
2
func^(lhs:Int,rhs:Int)->Int{
}
Operations in the function :
To make the power of the value we have to apply following operations
Xcode 7.3 came with Swift 2.2 Version. I just updated to Xcode 7.3 and found following warnings because of Swift version change.
List of warnings with it’s solution:
‘var’ parameters are deprecated and will be removed in Swift 3
Warning with:
[code language=”obj-c”]
func functionTest(var param:String) {
print(param)
}
[/code]
Solution:
[code language=”obj-c”]
func functionTest(param:String) {
print(param)
}
[/code]
If you want to update that variable inside the function then you have to create copy of that variable to do operations on that.
Use of string literal for Objective-C selectors is deprecated; use ‘#selector’ instead
Warning with:
[code language=”obj-c”]
btn.addTarget(self, action: "functionName", forControlEvents: UIControlEvents.TouchUpInside)
[/code]
OR
[code language=”obj-c”]
btn.addTarget(self, action: Selector("functionName"), forControlEvents: UIControlEvents.TouchUpInside)
[/code]
Solution:
[code language=”obj-c”]
btn.addTarget(self, action: #selector(ViewController.functionName), forControlEvents: UIControlEvents.TouchUpInside)
[/code]
Apple Documentation : Added information about the #selector syntax for Objective-C selectors to the Selector Expression section.
‘++’ is deprecated: it will be removed in Swift 3
Warning with:
[code language=”obj-c”]
var i = 0
for str in arrStr {
print(str)
i++
}
[/code]
Solution:
[code language=”obj-c”]
var i = 0
for str in arrStr {
print(str)
i += 1
}
[/code]
Apple Documentation : Removed discussion of C-style for loops, the ++ prefix and postfix operators, and the — prefix and postfix operators.
C-style for statement is deprecated and will be removed in a future version of Swift
Warning with:
[code language=”obj-c”]
for var i=0; i<arrStr.count; i += 1 {
print(arrStr[i])
}
[/code]
Solution:
[code language=”obj-c”]
for i in 0 ..< arrStr.count {
print(arrStr[i])
}
[/code]
__FILE__ is deprecated and will be removed in Swift 3, please use #file
EasyAnimation A Swift library to take the power of UIView.animateWithDuration(_:, animations:…) to a whole new level – layers, springs, chain-able animations and mixing view and layer animations together!
