Question 1

How to implement dark mode with Themes in Swift?

Accepted Answer

Define separate themes for light and dark modes (e.g., MyTheme instances), then switch ThemeManager.shared.currentTheme based on system settings or user input. Use the use() function in views to update colors and fonts in real-time.

Question 2

Themes vs other iOS theming libraries like SwiftTheme?

Accepted Answer

Themes focuses on protocol-oriented design for full control over custom properties and JSON backing, while SwiftTheme offers more drop-in theming with extensions. Themes is better for granular control, but SwiftTheme might be quicker for simple cases.

Question 3

Can Themes work with SwiftUI?

Accepted Answer

Not directly; Themes is designed for UIKit and uses protocol-oriented Swift. To integrate with SwiftUI, you'd need to wrap theme properties in ObservableObject or adapt the use() pattern, which isn't documented in the README.

Question 4

How to load themes from a JSON file in Themes?

Accepted Answer

Create a theme struct conforming to the Theme protocol and add a custom initializer that parses JSON dictionary keys into properties like colors and fonts. Then instantiate themes from backend data, as shown in the usage snippet.

Question 5

Does Themes support dynamic theme switching at runtime?

Accepted Answer

Yes, assigning a new theme to ThemeManager.shared.currentTheme triggers real-time updates across all views registered with the use() function, allowing seamless transitions like night mode toggles.

Question 6

How to handle theme updates in a UITableView with Themes?

Accepted Answer

In your view controller's viewDidLoad, use the use() function to set table view properties and call reloadData() if needed. In cells, use it in awakeFromNib to update labels and backgrounds, as demonstrated in the README examples.
