New Swift 2.2 Features to Boost Swift App Development Services
Find New Swift 2.2 Features to Boost Swift App Development Services. The author is an experienced Swift app developer.
With new syntax, new features and a bit deprecations of outdated features, Swift 2.2 is finally in the court. It’s time for Swift app developers to take their best shot and build outstanding apps that can deliver the best experience to iPhone or iPad users. If you are a Swift app development services provider, and want to hone your skills, spare some time to learn about new developments offered with Swift 2.2.
Compile-time Swift version checks
Finding it hard to keep your every Swift app developer on the same plane owing to release of subsequent versions of Swift? Swift 2.2 promises an end to the problem. The compiler of the current edition is competent in identifying the version type that would be able to run on a particular device. Thus, a Swift app developer has to merely indicate blocks of code that should be read only. For example:
#if swift(>=3.0)
print(“Running Swift 3.0 or later”)
#else
print(“Running Swift 2.2 or earlier”)
#endif
In the previous Swift version, runtime version check was possible that resulted into failure of the app, if the device was not compatible with an app build.
Compile-time checked selectors
The latest Swift edition can locate and debug coding issues caused due to typos as it discards the use of selectors. Instead, it pushes a new syntax called #selector. Thus, it checks problems much before an app is ready to be tested or published.
More keywords as argument labels
Leaving inout, var, and let, use your own set of keywords to do the coding. Choose keywords like class, func, let, and public that have special meaning and cannot be used as identifiers and make Swift app development easier. To fix any wrong labels, you can use Xcode Fix-it. This will help you to find and remove them in a quick and easy manner.
Tuple comparison is built-in
Tuples are basic data type in Swift that bring a host of advantages to a Swift app developer. However, we can’t ignore that they often return multiple values from functions. Thus, they create confusion in comparing one tuple against another. For example, the below code will print “No match”:
let singer = (first: “Taylor”, last: “Swift”)
let alien = (first: “Justin”, last: “Bieber”) if singer == alien {
print(“They match! That explains why you never see them together…”)
} else {
print(“No match.”)
}
Deprecated Features
Tuple splat syntax, C-style for loops and ++ and — operators have deprecated to make code writing simple and fast, and give a clear direction to Swift app developers who are new to project.
