Is there any way I can download the Spotify song through any Spotify Api or any other way because I developing a music application which change the song bpm (Beats Per Minutes). But I can’t change Spotify song bpm because Spotify song play online through Spotify methods with the Spotify premium account. So any way to download Spotify song.

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.Basic requirement : First make sure you have Xcode +10 installed and swift +4.
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
.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. https://uypqtr.weebly.com/blog/spotify-app-sweetlabs.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 ?Developer Showcase | Spotify For Developers
Download spotify hidownload. 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:Mac spotify upate. 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! Java Spotify Api
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
.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.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.See Full List On Developer.spotify.com
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:Cached
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.
