The SwiftUI Toolbar in iOS 14

Toolbars are amongst the interesting additions to SwiftUI’s second iteration during WWDC 2020.

Essentially, toolbar is a modifier that lets you place a wrap around a bunch of view controls and set them at desired locations.

By default, SwiftUI can smartly determine and set views at desired locations with the toolbar modifier, but you can also explicitly set it using ToolbarItem.

In the next few sections, we’ll look at:

• The need for the toolbar modifier
• Using Toolbar API to automatically set items in the bottom bar and navigation bar
• Using ToolbarItem for manual placements

Understanding Grids in SwiftUI for iOS 14

SwiftUI was announced at WWDC 2019 and it paved a way for declarative programming for building interfaces. SwiftUI Grid comes in two different flavours, which includes LazyVGrid and LazyHGrid. As the name suggest, LazyVGrid is a Grid that flows in vertical direction and the LazyHGrid flows in horizontal direction.

If you are interested in videos then check out the following videos associated with this post.

Each Grid consists of GridItem, which dictates the structure of the cell displayed in the grid. GridItem can be fixed, flexible or adaptive. Let’s start with the fixed size GridItems.

Fixed GridItems

var columns: [GridItem] = [

	        GridItem(.fixed(100)),
	        GridItem(.fixed(100)),
	        GridItem(.fixed(100))

	    ]

In the above code, we have created 3 fixed size columns of size 100. Now, we an easily use the LazyVGrid to create the columns and display information in the GridItem. This is shown below:

 NavigationView {

	            LazyVGrid(columns: columns) {

	                Rectangle()
	                    .fill(Color.red)
	                    .aspectRatio(contentMode: .fit)

	                Rectangle()
	                    .fill(Color.red)

	                Rectangle()
	                    .fill(Color.red)

	            }

	            .navigationTitle("LazyVGrid")
	        }

As you can see that for the content of LazyVGrid, we have used Rectangle but you can use any View you desire.

You can add more Rectangles to the LazyVGrid by running a ForEach. A ForEach loop will return a type View with each iteration. The implementation is shown below:

 NavigationView {

	            ScrollView {
	            LazyVGrid(columns: columns) {

	                ForEach(1..<20) { _ in
	                    Rectangle()
	                        .fill(Color.red)
	                        .aspectRatio(contentMode: .fit)
	                }

	            }}

	            .navigationTitle("LazyVGrid")
	        }
