feat(design-system/DT-6): allow generation of both UIKit and SwiftUI font files

[ada10086]

Making some updates based on my comments in the original fueled-typography PR

The main update is to allow generation of both UIKit's Label.swift, LabelStyle.swift, LabelStyle+extension.swift and SwiftUI's TextStyle.swift, TextStyle+extension.swift.

Question:

• Do we need a fontSystem parameter? I don't think it is necessary, since we have to specify the generated file path anyways in the yml if we want to generate certain files , we can simply check whether the file path exists, for the same reason, we could also remove the generateLabels and generateStyles params
• Do we want to include the example folder in our repo at all? Since there's a lot inside Example to maintain every time we make updates

TODO:

• fix tests
• update Example dir to reflect our changes or remove it
• potentially remove fontSystem param

DT-6 Update the generated file names, remove unused files

P.S. Will need to update the figma-export.yml with the right params for typography

  # [optional] Parameters for exporting typography
  typography:
    # Typography name style: camelCase or snake_case
    nameStyle: camelCase
    # [optional] Absolute or relative path to swift file where to export UIKit fonts (UIFont extension).
    fontSwift: "./Libraries/DesignSystem/Sources/FigmaExport/Extensions/UIFont+extension.swift"
    # [optional] Absolute or relative path to swift file where to generate LabelStyle extensions for each style (LabelStyle extension).
    labelStyleSwift: "./Libraries/DesignSystem/Sources/FigmaExport/Extensions/LabelStyle+extension.swift"
    # Should FigmaExport generate UILabel for each text style (font)? E.g. HeaderLabel, BodyLabel, CaptionLabel
    generateLabels: true
    # Relative or absolute path to directory where to place UILabel for each text style (font) (Required if generateLabels = true)
    labelsDirectory: "./Libraries/DesignSystem/Sources/FigmaExport/UIComponents/"
   
    # [optional] Absolute or relative path to swift file where to export SwiftUI fonts (Font extension).
    swiftUIFontSwift: "./Libraries/DesignSystem/Sources/FigmaExport/Extensions/Font+extension.swift"
    # [optional] Absolute or relative path to swift file where to generate TextStyle extensions for each style (TextStyle extension).
    textStyleSwift: "./Libraries/DesignSystem/Sources/FigmaExport/Extensions/TextStyle+extension.swift"
    # Should FigmaExport generate TextStyles for each text style (font)? E.g. Header, Body, Caption
    generateTextStyles: true
    # Relative or absolute path to directory where to place TextStyles for each text style (font) (Required if generateTextStyles = true)
    textStylesDirectory: "./Libraries/DesignSystem/Sources/FigmaExport/UIComponents/"

Do we not need UIFont anymore when only using SwiftUI? I did mention it here for clarity since we needed it to calculate the lineSpacing.

[ada10086]

Oh I see your intention here, I thought we simply wanted to note what extension file we are creating. I will add additional comments here to clarify!

[ada10086]

Also maybe the parameter fontSwift, i.e. UIFont extension, should be non-optional, since it'll be required for not only UIKit but also SwiftUI?

How do you allow both at the same time?

[ada10086]

Actually I was wondering if we could just remove the fontSystem param (See my question 1 above), wondering your thoughts on this ?
