The missing iOS radio buttons group.
Usage

radioGroup.selectedIndex = 0

SwiftUI Usage

.fixedSize()
Changing Appearance
The properties below can be set in Interface Builder, in code, or through a UIAppearance
proxy (e.g., RadioGroup.appearance().titleColor = .red
).
When using SwiftUI you can set them in the RadioGroupPicker
initializer, or use as view modifiers (e.g., .buttonSize(32)
). .
Layout:
radioGroup.isVertical = false // default is true => buttons are stacked vertically
radioGroup.titleAlignment = .right
radioGroup.isButtonAfterTitle = true // default is false => button left (leading) relative to title
Color and Font:
radioGroup.tintColor = .green // surrounding ring
radioGroup.selectedColor = .red // inner circle (default is same color as ring)
radioGroup.selectedTintColor = .blue // selected radio button's surrounding ring (default is tintColor)
radioGroup.titleColor = .blue
radioGroup.titleFont = myFont
Or use attributed strings:
radioGroup.attributedTitles = [
NSAttributedString(string: "Italic", attributes: [.obliqueness: 0.3]),
NSAttributedString(string: "Underline", attributes: [.underlineStyle: 1]),
]
Size:
radioGroup.buttonSize = 42.0
radioGroup.spacing = 12 // spacing between buttons
radioGroup.itemSpacing = 12 // horizontal spacing between button and title
Button appearance:
RadioButton.appearance().size = 32 // height=width of button
RadioButton.appearance().ringWidth = 3
RadioButton.appearance().ringSpacing = 7 // space between outer ring and inner circle
RadioButton.appearance().selectedColor = .blue // color of inner circle
