How to Resize ProgressView in SwiftUI

#What is ProgressView? ?

ProgressView is a component in SwiftUI used to display the progress of a process or similar tasks, whether in linear or circular form.

struct ProgressView<Label, CurrentValueLabel> where Label : View, CurrentValueLabel : View

However, ProgressView may appear too small by default, as shown in the image below.

import SwiftUI

struct ContentView: View {
    var body: some View {
        VStack {
            ProgressView("Sedang memproses...")
            
            Text("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Proin efficitur in ligula ac venenatis. Pellentesque hendrerit ipsum ac magna lacinia lacinia. Pellentesque bibendum dolor molestie magna accumsan ullamcorper.")
                .padding(.top)
        }
        .padding()
    }
}

#Resizing ProgressView using scaleEffect

To change the size of ProgressView, you can use the scaleEffect(_ s: CGFloat, anchor: UnitPoint = .center) modifier. Simply add this modifier with the desired value and anchor point.

struct ContentView: View {
    var body: some View {
        VStack {
            ProgressView("Sedang memproses...")
                .scaleEffect(2, anchor: .center)
            
            Text("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Proin efficitur in ligula ac venenatis. Pellentesque hendrerit ipsum ac magna lacinia lacinia. Pellentesque bibendum dolor molestie magna accumsan ullamcorper.")
                .padding(.top)
        }
        .padding()
    }
}

In the image above, not only does the size of ProgressView change, but the label also scales.

#Separating the label from ProgressView

Therefore, if you only want to resize the Progress itself, separate the text/label from your ProgressView as follows.

struct ContentView: View {
    var body: some View {
        VStack {
            ProgressView()
                .scaleEffect(2, anchor: .center)
                .padding()
            Text("Sedang memproses...")
                .foregroundColor(.secondary)
            
            Text("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Proin efficitur in ligula ac venenatis. Pellentesque hendrerit ipsum ac magna lacinia lacinia. Pellentesque bibendum dolor molestie magna accumsan ullamcorper.")
                .padding(.top)
        }
        .padding()
    }
}

#Conclusion

The size of ProgressView can be adjusted using the scaleEffect modifier. However, keep in mind that this modifier not only scales the ProgressView but also the label within it. Additionally, excessively large scaleEffect values can distort the appearance of ProgressView, making it appear blurry. Therefore, choose an appropriate scale value that is not too large.
