Maintenance release

Variable font, styles, metrics and colors

This release is a major overhaul of SRG Appearance.

Variable font

The SRG SSR font is now variable with support for arbitrary weights. Both the text and display fonts are provided.

Styles

SRG Appearance now provides several built-in styles which corresponds to fixed sizes, weights and scaling behaviors, defined both for iOS and tvOS. Your designs can benefit from using these standard styles across platforms.

If your application does not want to use the standard styles we provide SRG Appearance still provides an API with which you can define your own styles.

Remark

Standard styles support XS, S, M, L, XL and XXL content sizes, but not accessibility sizes. Accessibility sizes are namely tricky to support from a layout perspective. If your application still wants to support such sizes you should define your own styles, which can support arbitrary content sizes.

Metrics

SRG Appearance provides UIFontMetrics matching its styles (as well as the @SRGScaledMetric property wrapper for SwiftUI) which allows you to scale scalar values depending on content size settings.

Colors

Several gray colors have been added.

Swift and SwiftUI support

SRG Appearance now provides improved APIs for Swift and SwiftUI. Swift code must link against SRGAppearanceSwift to use these APIs.

Minimum deployment target

The minimum deployment target has been bumped to iOS 12.

Assertion removal in release builds

Ensure assertions are never fired in release builds.

Xcode crash fix

This release packages resources differently to avoid Xcode crashing for some projects when attempting to run a unit test target.
