Announced in 2014, the Swift programming language has quickly become one of the fastest growing languages in history. Swift makes it easy to write software that is incredibly fast and safe by design.

What are the Design and Architecture?
The design is more often seems to when it comes to structures and low-level decisions whereas Architecture is often used in the context of something at the high level where we can see how components are connected with each other. But for starters, there is no different at all.
What is the GOAL of good software design?
The goal of software architecture is to minimize the Human Resources required to build and maintain the required system (By Uncle Bob Martin)
Basic fundamentals measure the design?
The measure of design quality is simply the measure of the effort required to meet the needs of the customer if the effort is low and stays same through the lifetime, System design is good else it’s bad.
The Signature of a system design mess?
- Developer point of view
The graph says developers started with nearly 100% of productivity but with each release, their productivity going down
- Executive point of view?
Release 1 was delivered with a few hundred thousand payrolls and by the time of 5 release, it’s going to touch $500,000.
What is going wrong?
The moral of the story says everything in one line: “Slow and steady wins the race”. Yes, it all because of overconfidence. Everyone wants to hit the market first or release the app asap with the statement “We can clean it up later” and they can’t go back for cleaning the things up because now we have the new feature, new release so maybe next time, next time and next time.
The only way to go fast is to go well.
To take the software architecture seriously we have to think and need to know what good software architecture is, compare the different architecture with the requirements.

- Structs are the value type.
- Classes are the reference type.
- Properties of a constant instance of the struct are immutable because struct’s instance own the whole object and by declaring it as a constant means the whole object itself will be immutable.
- Properties of a constant instance of the class are mutable as class’s instance owns the object’s reference thus by declaring it as a constant only means that the further reference assignment can’t be done.
- Structs are blessed with default member-wise initializer but classes are not.
- Structs are preferable when they are small and copyable.
- With Structs, there is much less need to worry about memory leaks or multiple threads racing to access/modify a single instance of a variable.
- Since struct instances are allocated on the stack, and class instances are allocated on the heap, structs can sometimes be drastically faster (but it still depends on how many values you’re storing and the size/structure.)
- In a multi-threaded environment, for instance, with a database connection that’s opened in a different thread, structs are safer. They can be copied from one thread to another thread, without running the risk of a race condition or deadlock. Classes do not have this inherent safety unless they’re deliberately made thread-safe.

“Today is all about Software,” Apple CEO Tim said as he took the stage at WWDC 2018.
It all started with statistics.
- 20 million iOS developers
- 500 million weekly app store visits
- 81% using iOS 11 where only 8% using latest Android
- Developers earned 100 million through App Store
- New iOS 12 will be released as a free update, every model back to the 5S will get a performance boost.
- ARKit, second generation, which included a lot of cool updates, most interesting is the ability for multiple users to observe and interact with the same environment from different angles.
- Apple Screen time, now iOS 12 will tell you how much time you’re spending with your iPhone and which are the apps.
- Do not disturb a lot of improvements, while you are sleeping will hide the notification, one step one time notifications.
- Photos, with iOS 12 they have revamped it. Allowing more search options driven by AI, share the photos through iMessage.
- Siri, it’s handling 10 billion requests per month and now Apple is allowing you to interact with it more, create shortcuts to trigger app features.
- Animojis, more personal now. It’s super accurate, face-tracking and tongue tracking capabilities. Surely it will feel you very familiar.
- Group FaceTime, now chat with 32 people at once with emoji, sticker, and other effects support.
iOS Apps updates
- Stocks, new UI with better performance
- Apple News app.
- Apple iBooks getting a redesign and a new name.
- Voice Memos, iPad getting it for the first time and recording will be now synced to iCloud.
So far biggest functions of the Apple iWatch is fitness, now Apple adding more components which let you challenge your friends.
- Automatic workout detection using your heart-beats(once you stop working out your heart rate decreases, so it will automatically stop).
- Walkie-Talkie, Texting/phone are tough using watch screen so Apple added an instant audio messaging app called walkie-talkie (uses the wifi or cellular to interact with other devices).
- Siri on Watch, allow third-party apps to show you more information. Now just lift your wrist and start talking it means no more “Hey Siri”.
- Podcasts app is coming on your wrist.
How to use Swift classes into Objective Code when you have multiple targets.
For using Swift classes in Objective-C Code when you have one target in your app. We generally need to and
import TargetName-Swift.h next to add support in your Swift file you need to inherit if from
NSObject or use
What if you have multiple targets in your codebase? As you cannot import,
TargetNameB-Swift.h etc. In that case, you can tell the compiler that not to create Swift module specific to target change it to project name because the project will be same and unique.
For achieving this select your every target, Build Settings and change the build configuration.
Objective-C Generated Interface Header Name —> replace $(SWIFT_MODULE_NAME)-Swift.h that is specific to the each target, with $(PROJECT_NAME)-Swift.h
Later import PROJECT_NAME-Swift.h in your Objective C code to make use of your Swift code.
Yes, correct you heard it right. It was the most awaited feature because nobody wants to spend a lot on Apple connectors, haha. But unfortunately, I don’t see people are utilizing this features. So here we go with one to kick start.
iOS device with later or
iOS 11 OS version.
- MacBook with
macOS 10.12.4 or later.
Xcode IDE with 9 or later
- Developer Macbook and
iOS device should be on same WiFi network.
I hope after reading prerequisites you are clear about what is gonna happen. Let’s move on further steps.
Step: 1 Here you need your connector cable for first and yes last time. Connect your iOS device and open Xcode.
Step 2: Switch to,
Devices and Simulators options, below is the screen for reference.
Step 3: Just enable the option
Connect via network.
Step 4: Sometimes it will ask you to provide your
iOS device IP to enter but in my case, it didn’t ask.
