A font picker for SwiftUI, in a similar style to Apple's Color Picker

FontPicker

A Font Picker in a similar style to Apple's Color Picker, providing a means of choosing a font from the available UIFont familyNames. I'm not 100% sure that all of these font names work in SwiftUI, but they seem to.

Installation

Swift Package Manager

In Xcode:

• File ⭢ Swift Packages ⭢ Add Package Dependency...
• Use the URL https://github.com/franklynw/FontPicker

Example

NB: All examples require import FontPicker at the top of the source file

It can be used directly as a view, which offers the full range of customisation options -

var body: some View {
    
    FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
        .additionalFontNames(["MySpecialFont"])
        .excludedFontNames(["Marker Felt"])
        .backgroundColor(viewModel.fontPickerBackgroundColor)
}

or as a modifier, which presents the default font picker (with no customisation options) -

var body: some View {

    MyView {
    
    }
    .fontPicker(isPresented: $isFontPickerPresented, Binding: $viewModel.selectedFont)
}

Specify the fonts you want to be shown

If you use this modifier, it will only show the fonts you specify

FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
    .fontNames(viewModel.allTheBestFonts)

Specify the fonts you'd like to add to the default list

This will show all of the available system fonts, plus any you pass in here

FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
    .additionalFontNames(viewModel.myUniqueFonts)

Specify the fonts you'd like to not be shown

This will show all of the available system fonts, minus any you pass in here

FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
    .excludedFontNames(viewModel.rubbishFonts)

Disable the automatic "dismiss on selection" functionality

This might be necessary if you have (eg) a preview visible above the picker, where you can see how your selected font looks - the user can then decide when to dismiss the picker

FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
    .disableDismissOnSelection

Set the picker's background colour

FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
    .backgroundColor(.lightGray)

Set the height of the picker as either a fixed height or as a proportion of the containing view's height

FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
    .height(.fixed(400))

or

FontPicker(isPresented: $isFontPickerPresented, selected: $viewModel.selectedFont)
    .height(.proportional(0.6))

Additionally...

There are two NotificationCenter notifications which are sent, which are defined as static vars on Notification.Name -

• fontPickerAppeared ("FontPickerAppearedNotification")
• fontPickerDisappeared ("FontPickerDisappearedNotification")

These are sent as their names suggest, and there is no additional userInfo

Dependencies

Requires HalfASheet, which is linked. Take a look at it here

fontpicker's Issues

System fonts not displaying

This is a very simple issue but I'm missing the default system fonts, i.e.:

• SF Pro
• SF Mono
• SF Rounded
• New York

They simply do not show in the list.
