In this post we will try to re-create the Spotify home screen layout in Swift programmatically. Why programmatically? I think it's always good to know how to build things in different ways, and I like to write code to do things programmatically. These skills are especially helpful if you are working with team or using version control.
This is the actual home screen of Spotify's mobile app. So to achieve this kind of layout, we will be using
UICollectionView
, and we may use TabBarController
as well to create the tab navigator.Here’s our Top 40 playlist for software developers, ranking the most productive songs based on coding productivity data from thousands of Music Time users. Every week we publish the hot coding songs developers are listening to as they recode the world. The final word on coding languages for iOS apps. In this article, you’ve learned the basics for getting started with your iOS app. You’ve learned that coding your own app isn’t the easiest, fastest, or cheapest way to get your app to market. Coding an iOS app yourself, especially if you’re new to development, is tedious and time-consuming.
Basic requirement : First make sure you have Xcode +10 installed and swift +4.

Swift is a powerful and intuitive programming language for iOS, macOS, tvOS, and watchOS. Writing Swift code is interactive and fun, the syntax is concise yet expressive, and Swift includes modern features developers love. Swift code is safe by design, yet also produces software that runs lightning-fast.
Let's start by creating a new Xcode project using Xcode:
And the first thing we need to do in
ViewController.swift
is change the superClass to UICollectionViewController
instead of UIViewController
because our class will be based on collectionView
.If you try to run the app the build will fail. We need to add some code to the
AppDelegate.swift
file within the didFinishLaunchingWithOptions
function past this piece of code before the return
statement:And the code should look like this:
Now you should be able to run the app and see the
backgroundColor
changed to purple
:The next step is to distribute the layout and divide the space equally between the sections.
Let's define the methods of our
CollectionView
.To listen to Spotify on your speaker or display, you must link your Spotify account. There are a couple of ways to listen to music using Spotify. Spotify Premium. If you have a Spotify Premium account you can play content on demand. You can get specific songs, albums, or artists along with music based on genre, mood or activity, Spotify. https://clevermedicine767.weebly.com/can-i-use-spotify-free-on-google-home.html. Three Ways to play Spotify Music on Google Home/Mini/Max, whether free or premium, you can directly play Spotify on Google Home using Bluebooth connection, setting Spotify as your default music service, or download and convert Spoitfy music to MP3, upload the MP3 songs to Google Play Music and use Google Home. For Google Home's best music setup, do these steps right away with Spotify, YouTube Music and more. Your Google Home or Nest smart speaker can play almost any song ever recorded, but first you. 6 things to know about the new free Spotify. The world's largest music-streaming service just amped up its freebie options. Here's what you need to know. I've been using Spotify for as long as I can remember, either with a shared family account, a free Facebook account, and for the last past 5 years a Spotify Premium account. I'm sorry to say that, as long as I've been using Spotify.
The steps:
- Register a reusable cell with unique identifier
- Define the number of the items in the section
- Use the the registered cell
To use some of
CollectionView
methods we need to always conform to UICollectionViewDelegateFlowLayout
as a superClass and to get the autoComplete of the methods. So let's start with registering the CollectionViewCell.Inside
View.DidLoad()
we call the collectionView.register()
method to register the reusable cell:Then we define the number of cells we will have inside the
collectionView
using numberOfItemsInSection
. For now we just need to make it 5 items:The next step is to define the reusable cell using
cellForItemAt
that should return UICollectionViewCell
and have a unique id called cellId
. The code looks like this:The full code should look like this:
You should be able to see 5 items with red backgrounds on the screen:
Add a custom width and height to the cells
Now we need to place the cells in the correct order and give them a
width
and height
. Each cell will take the width
of the screen as width
.We are lucky to have
sizeForItemAt
method so we can give the cells a custom width
and height
. It's a method that should return a CGSize
type:So we made the
Cell
take the width
of the screen by using view.frame.width
and a custom height
with is a CGFloat
type.Now you can see the result below in your Simulator :
Everything looks good so far. This time let's create a custom cell that can be reusable. Create a new Swift file named
CustomCell
:CustomCell.swift
should look like this below:Now the next things we have to do is to modify two methods to support the reusable cell,
collectionView.register
and cellForItemAt
. Let's first modify the register method. Replace UICollectionViewCell.self
with CustomCell
:Next we need to cast
cellForItemAt
to conform to CustomCell
like below:If you run the app probably you won't notice any change, so give the CustomCell a backgroundColor
backgroundColor = .yellow
. Don't forget to remove the line cell.backgroundColor = .red
in cellForItemAt
. You should see the background color changed to yellow ?Now it's time to put some salt into
CutomCell
:DIf you look at the Spotify home screen, each section which is a
CustomCell
in our example contains a section title, sub cells, and is horizontal:Add a section title
Let's add a title label to the cell. Create the
titleLabel
element inside the CutomCell
class:Then add the element to the view inside
init()
block:If you run the app you won't see any changes, and that's because we didn't put any constraint to the element yet. So let's add some constraints – add this property
lb.translatesAutoresizingMaskIntoConstraints = false
totitleLabel
to be able to apply constraints to the element:After we add
titleLabel
to the view, we define the constraints:Always make sure to add
.isActive = true
property – without it the constraint won't work! Before we move on to the next part, let's first change the background color of the screen to black and also remove the yellow color for the cells:
Now comes the big part: putting sub cells into each cell. To achieve that we are going to add a
CollectionView
inside CustomCell
.To add a
CollectionView
inside UICollectionViewCell
we need to add properties UICollectionViewDelegate
, UICollectionViewDelegateFlowLayout
, and UICollectionViewDataSource
as superClass to CustomCell
.Coding An App For Spotify In Swift Playlist
Let's create the
collectionView
element as any simple view:Notice that we add
layout
to the collectionView
as layer in the initializer as we did the first time with the viewController.swift
. Here we also specify the direction of the FlowLayout
to be .horizontal
.Let's add the
collectionView
element to the view as subView. We gonna make a function that do that for us to make the code a little bit cleaner.
Make sure to set delegate to
self
for the collectionView
and the dataSource as well:collectionView.dataSource = self
collectionView.delegate = self
Then call the function within
init
block.Coding An App For Spotify In Swift Id
Xcode will display some errors if you trying to build the app because we are not conforming to
UICollectionViewDelegate
and UICollectionViewDelegateFlowLayout
protocols. To fix that we need first to register the sub cell as a reusable cell.Create a variable at the top of the class and give it a name of
cellId
so we can use it when we need the cell identifier: let cellId : String = 'subCellID'
Now we're missing two more methods to make the errors go away:
numberOfItemsInSection
that define the number of cells in the section and cellForItemAt
that define the reusable cell. These methods are necessary for collectionView
to work properly:The results should look like this:
As you can see, the
collectionView
are in purple as background and sub cells are yellow.The last things we can do before ending this article is make
subCells
have the height of the section and as width. Again we are using sizeForItemAt
to define the height
and the width
of the cell .And here we are ?:
NICE! I'm gonna stop at this point so this post isn't too long. I'll make a second part where we are going to add some mocked pictures and fill it with some data.
Spotify premium users free google home. Is back this year, gifting users of its premium tier subscription with a free Google Home Mini. The big one is, if you claimed the Home Mini last year, you’re not eligible this time around for another free device. The same thing, but unlike then, folks on an individual plan (and not just a family plan) can get a free Home Mini.To claim, there are a few requirements and terms you need to know about.

The powerful programming language that is also easy to learn.
Swift is a powerful and intuitive programming language for macOS, iOS, watchOS, tvOS and beyond. Writing Swift code is interactive and fun, the syntax is concise yet expressive, and Swift includes modern features developers love. Swift code is safe by design, yet also produces software that runs lightning-fast.
Modern
Swift is the result of the latest research on programming languages, combined with decades of experience building Apple platforms. Named parameters are expressed in a clean syntax that makes APIs in Swift even easier to read and maintain. Even better, you don’t even need to type semi-colons. Inferred types make code cleaner and less prone to mistakes, while modules eliminate headers and provide namespaces. To best support international languages and emoji, Strings are Unicode-correct and use a UTF-8 based encoding to optimize performance for a wide-variety of use cases. Memory is managed automatically using tight, deterministic reference counting, keeping memory usage to a minimum without the overhead of garbage collection.
Declare new types with modern, straightforward syntax. Provide default values for instance properties and define custom initializers.
Add functionality to existing types using extensions, and cut down on boilerplate with custom string interpolations.
Quickly extend your custom types to take advantage of powerful language features, such as automatic JSON encoding and decoding.
![Swift Swift](/uploads/1/3/3/8/133849255/851071170.jpg)
Perform powerful custom transformations using streamlined closures.
These forward-thinking concepts result in a language that is fun and easy to use.
Swift has many other features to make your code more expressive:
- Generics that are powerful and simple to use
- Protocol extensions that make writing generic code even easier
- First class functions and a lightweight closure syntax
- Fast and concise iteration over a range or collection
- Tuples and multiple return values
- Structs that support methods, extensions, and protocols
- Enums can have payloads and support pattern matching
- Functional programming patterns, e.g., map and filter
- Native error handling using try / catch / throw
Designed for Safety
Swift eliminates entire classes of unsafe code. Variables are always initialized before use, arrays and integers are checked for overflow, memory is automatically managed, and enforcement of exclusive access to memory guards against many programming mistakes. Syntax is tuned to make it easy to define your intent — for example, simple three-character keywords define a variable ( var ) or constant ( let ). And Swift heavily leverages value types, especially for commonly used types like Arrays and Dictionaries. This means that when you make a copy of something with that type, you know it won’t be modified elsewhere.
Another safety feature is that by default Swift objects can never be nil. In fact, the Swift compiler will stop you from trying to make or use a nil object with a compile-time error. This makes writing code much cleaner and safer, and prevents a huge category of runtime crashes in your apps. However, there are cases where nil is valid and appropriate. For these situations Swift has an innovative feature known as optionals. An optional may contain nil, but Swift syntax forces you to safely deal with it using the ? syntax to indicate to the compiler you understand the behavior and will handle it safely.
Use optionals when you might have an instance to return from a function, or you might not.
Features such as optional binding, optional chaining, and nil coalescing let you work safely and efficiently with optional values.
Fast and Powerful
From its earliest conception, Swift was built to be fast. Using the incredibly high-performance LLVM compiler technology, Swift code is transformed into optimized native code that gets the most out of modern hardware. The syntax and standard library have also been tuned to make the most obvious way to write your code also perform the best whether it runs in the watch on your wrist or across a cluster of servers.
Swift is a successor to both the C and Objective-C languages. It includes low-level primitives such as types, flow control, and operators. It also provides object-oriented features such as classes, protocols, and generics, giving Cocoa and Cocoa Touch developers the performance and power they demand.
Great First Language
Swift can open doors to the world of coding. In fact, it was designed to be anyone’s first programming language, whether you’re still in school or exploring new career paths. For educators, Apple created free curriculum to teach Swift both in and out of the classroom. First-time coders can download Swift Playgrounds—an app for iPad that makes getting started with Swift code interactive and fun.
Aspiring app developers can access free courses to learn to build their first apps in Xcode. And Apple Stores around the world host Today at Apple Coding & Apps sessions where you can get hands-on experience with Swift code.
Source and Binary Compatibility
With Swift 5, you don’t have to modify any of your Swift 4 code to use the new version of the compiler. Instead you can start using the new compiler and migrate at your own pace, taking advantage of new Swift 5 features, one module at a time. And Swift 5 now introduces binary compatibility for apps. That means you no longer need to include Swift libraries in apps that target current and future OS releases, because the Swift libraries will be included in every OS release going forward. Your apps will leverage the latest version of the library in the OS, and your code will continue to run without recompiling. This not only makes developing your app simpler, it also reduces the size of your app and its launch time.
Open Source
Swift is developed in the open at Swift.org, with source code, a bug tracker, forums, and regular development builds available for everyone. This broad community of developers, both inside Apple as well as hundreds of outside contributors, work together to make Swift even more amazing. There is an even broader range of blogs, podcasts, conferences and meetups where developers in the community share their experiences of how to realize Swift’s great potential.
Cross Platform
Swift already supports all Apple platforms and Linux, with community members actively working to port to even more platforms. With SourceKit-LSP, the community is also working to integrate Swift support into a wide-variety of developer tools. We’re excited to see more ways in which Swift makes software safer and faster, while also making programming more fun.

Swift for Server
While Swift powers many new apps on Apple platforms, it’s also being used for a new class of modern server applications. Swift is perfect for use in server apps that need runtime safety, compiled performance and a small memory footprint. To steer the direction of Swift for developing and deploying server applications, the community formed the Swift Server work group. The first product of this effort was SwiftNIO, a cross-platform asynchronous event-driven network application framework for high performance protocol servers and clients. It serves as the foundation for building additional server-oriented tools and technologies, including logging, metrics and database drivers which are all in active development.

Playgrounds and Read-Eval-Print-Loop (REPL)
Much like Swift Playgrounds for iPad, playgrounds in Xcode make writing Swift code incredibly simple and fun. Type a line of code and the result appears immediately. You can then Quick Look the result from the side of your code, or pin that result directly below. The result view can display graphics, lists of results, or graphs of a value over time. You can open the Timeline Assistant to watch a complex view evolve and animate, great for experimenting with new UI code, or to play an animated SpriteKit scene as you code it. When you’ve perfected your code in the playground, simply move that code into your project. Swift is also interactive when you use it in Terminal or within Xcode’s LLDB debugging console. Use Swift syntax to evaluate and interact with your running app, or write new code to see how it works in a script-like environment.
Package Manager
Swift Package Manager is a single cross-platform tool for building, running, testing and packaging your Swift libraries and executables. Swift packages are the best way to distribute libraries and source code to the Swift community. Configuration of packages is written in Swift itself, making it easy to configure targets, declare products and manage package dependencies. New to Swift 5, the swift run command now includes the ability to import libraries in a REPL without needing to build an executable. Swift Package Manager itself is actually built with Swift and included in the Swift open source project as a package.
Objective-C Interoperability
You can create an entirely new application with Swift today, or begin using Swift code to implement new features and functionality in your app. Swift code co-exists along side your existing Objective-C files in the same project, with full access to your Objective-C API, making it easy to adopt.
