What’s Included

The design system in the kit includes the basics:

• Colors (Light+Dark Mode)
• Icons
• Button styles (SwiftUI, Light+Dark Mode)
• Text styles (SwiftUI, Light+Dark Mode)

Example code implementations via Swift Previews:

• General UI elements (buttons, toggles…)
• Common navigation components (tab bar, side bar…)
• Screen templates

Colors (Light+Dark Mode)

Hardware Illustrations

Icons Filled

Icons Outline

Additionally, there are example code implementations via Swift Previews specific to Bitcoin wallets, such as:

• Balance display
• Transaction display
• Address input
• Fee selection

It also includes some example code implementations via Swift Previews of detailed user flows, such as:

• Onboarding
• Creation and import of single and multi signature wallets
• Sending
• Receiving
• Settings
• Transaction management
• Coin mixing

Basic Usage

Colors (Light+Dark Mode)

SwiftUI

Text("Bitcoin Orange")
    .font(.caption)
    .foregroundColor(.bitcoinOrange)
    .multilineTextAlignment(.center)

UIKit

let label = UILabel()
label.frame = CGRect(x: 200, y: 200, width: 200, height: 20)
label.text = "Bitcoin Orange"
label.textColor = .bitcoinOrange

Icons

SwiftUI

BitcoinImage(named: "coldcard")
    .resizable()
    .aspectRatio(contentMode: .fit)
    .frame(height: 75.0)

UIKit

let image = BitcoinUIImage(named: "coldcard")
let imageView = UIImageView(image: image)
imageView.frame = CGRect(x: 0, y: 0, width: 75, height: 75)
view.addSubview(imageView)

Button Styles

Three button styles are implemented in SwiftUI; BitcoinFilled, BitcoinOutlined and BitcoinPlain. They have a number of optional parameters, including: width, height, cornerRadius, tintColor, textColor, disabledFillColor and disabledTextColor depending on the type.

SwiftUI

Button("Filled button") {
    print("Button pressed!")
}
.buttonStyle(BitcoinFilled())

Button("Outlined button") {
    print("Button pressed!")
}
.buttonStyle(BitcoinOutlined())

Button("Plain button") {
    print("Button pressed!")
}
.buttonStyle(BitcoinPlain())

Text Styles

Ten text styles are implemented in SwiftUI; BitcoinTitle1 - BitcoinTitle5 and BitcoinBody1 - BitcoinBody5

SwiftUI

Text("Title")
    .textStyle(BitcoinTitle1())

Text("Body")
    .textStyle(BitcoinBody1())

Requirements

WalletUI currently requires minimum deployment targets of iOS 15.

Installation

You can add WalletUI to an Xcode project by adding it as a package dependency.

1. From the File menu, select Add Packages…
2. Enter “https://github.com/reez/WalletUI" into the package repository URL text field
3. Depending on how your project is structured:
   • If you have a single application target that needs access to the library, then add WalletUI directly to your application.
   • If you want to use this library from multiple targets you must create a shared framework that depends on WalletUI and then depend on that framework in all of your targets.
