Swift 4 – A Step Ahead to The Most Advanced Programming Language – iOS Development

Hey, welcome back!!! Let’s move one step ahead with the open source development language from Swift 3 to Swift 4. We, at 9series, have filtered out points of our next strides in developing mobile apps using Swift 4.

Swift 4

Swift 4 is the latest major release for iOS App Developer that is intended to be completed in the fall of 2017. Its main focus is to provide source compatibility with Swift 3 code while implementing essential feature work that needs to achieve binary stability in the language. It will contain valuable enhancements to the core language and Standard Library, particularly in the generics system and an overhaul of the String type.

Source Compatibility Modes

The Swift 4 compiler will provide two language modes: Swift version 3 and Swift version 4. Swift 3 established the language for source-level stability and now Swift 4 releases source compatibility as a feature moving ahead.

    • Swift 3 mode is default for existing code and will build source code that works with the Swift 3 compiler
    • Swift 4 mode allows you to use new features and performance optimizations of Swift 4, some of which may require migration
    • Mixed mode allows you to take advantage of interoperability between binaries built with the same compiler. The proposed design is that a project containing various Swift modules, such as a Xcode project with multiple Swift targets, will be able to ratify into the specific Swift language mode on per module (target) level and that they can smoothly interact within the same compiled binary.

New Features in Swift 4

    • Swift 4 presents another codable protocol that gives a chance to serialize and deserialize custom data types without composing any special code – and without worrying about losing your value types
    • Quicker and simpler to use strings that retain Unicode correctness and add support for using, creating and managing substrings
    • Smart key paths for type-safe, effective and extensible key value coding for Swift types
    • Enhancements to create and manipulate Dictionary and Set types

Swift has many other features to make your code more expressive:

Multi-Line String Literals

To start a string literal, you need to write three double quotation marks: “”” then press return. After pressing return key, start writing strings with any variables, line breaks and double quotes. To end multi line string literal again write ””” in new line. Ex:-

1

Strings are Collections

Just like in earlier version of Swift, Strings can be handled as a collection. No need to writestring.characters.something to perform string manipulation.

2

Dictionary Functionality has Improved

Swift 4 combines some additional functionality to dictionaries to make them more strong, and also to make them work more like you would expect. Let’s start with a simple example: Modifying dictionaries in Swift 3 does not return a new dictionary. Instead, it returns an array of tuples with key/value labels.

3

After that code runs you can’t read distinction[“Maths”] because it is no longer a dictionary. Instead, you need to use distinction[0].value, which is not good for us because we apply filter on dictionary and we got an array.

As of Swift 4, this acts more like you would expect: you get back a latest dictionary. Obviously this will break any existing code that relies on the array return type.

Similarly, the map() method on dictionaries got a key-value tuple passed in, and could return a single value to be added to an array.

4

That has not changed in Swift 4, but there is a new method called mapValues(). It allows you to modify the values and place them back into a dictionary using the original keys.

Here we try to form different buckets where each bucket will contain values having same first character in their name. For Example:-.

5

It’s now likely to obtain a dictionary key and provide a default value to use if the key is missing. In following statement if there is no value for key “Bio” found then it will print default value.

6

Built in Encoding and Decoding

Swift 4 appears with built-in encoders and decoders for JSON. JSON to Model conversion comes in built in.

7

One Sided Range

Swift 4 introduces Python-like one-sided collection slicing, where the missing side is automatically assumed to be the start or end of the collection.

8

Conclusion

Like with other Swift releases, 4.0 was announced at WWDC ’17 and released in beta form for developers alongside Xcode 9. This release of Swift added quite a few refinements and features to the programming language. First release of Swift 4.0 will bring overall stability to the source and binary interface, or ABI.

Apple Pay vs Android Pay: Which is Better?

Apple Pay vs Android Pay

Google Wallet is an alternative of Apple Pay Let’s find out which is the better, Android Pay or Apple Pay?

Android Pay and Apple Pay are wireless payment systems for Android and iOS respectively. Apple Pay was one of the beginners of the card-free payment system. It was announced in September 2014 along with the iPhone 6 while the Google has just been discussed it at Google I/O 2015. This is after Google Wallet (originally) being mentioned back in March 2015.

Are Android Pay and Apple pay similar?

The technological answer is yes. Both use Near Field Communication (NFC) based technology in real-world scenarios and both offer one-touch online payments. Basically, the only real difference is a platform, it is running on – if the user has an iOS device, will use Apple Pay and if a user has an Android device will have to use Android Pay.

Apple Pay has the edge over Android is, it works on Apple Watch, whereas Android Pay so far only seems to work on Android device and not in Android Wear.

Android Pay vs Apple Pay: Which is more secure?

Both services seem secure as of: neither system transmits user’s actual card details to the retailer, but instead creates “virtual” card that is used purely for that transaction. In effect, it means two different transactions are taking place: one between Google/Apple and the retailer, where the retailer receives payment for the sale, and one between Google/Apple and user, where Google/Apple gets reimbursed by users.

In a way, It’s a better approach, because if recall any of the major retail card breaches of the last few years – Target, TJ Maxx and so on – it was the retailer systems which got hacked, not the banks. If user use Android Pay or Apple Pay and the retailer that user used gets hacked, any details they get about the user will be completely unusable.

Over 700,000 retailers in U.S. who accepts contactless payments, will also accept Android Pay too. The services will be accessible for in-app purchases from Uber, Lyft, Hotel Tonight and many more. Android phone owners with their fingerprint readers will be able to authorize purchases, similar to Apple Pay.

As both systems use similar security, the same basic technology and also have the similar aims. They are simply the wireless payment systems for their respective OSs. Justifying this, old phones will be able to use Android Pay but in Apple, only the latest iPhones can make use of Apple Pay. There many iPhone application development company india who can help in developing such a facility for your business.

At the end it’s a user who is going to get maximum benefits out of it. Intense competition between Apple Pay and Android Pay will encourage both to create the best product experience. There is many mobile app solutions and services provider company in India. At 9series we create a state of art experience to integrate both of them; if you have requirement then let’s talk.
