Accepted Answer

Format offers a cleaner, more concise API for common tasks like currency and decimals with built-in locale handling, but NumberFormatter provides more granular control and customization for complex formatting scenarios.

Question 3

How to convert a hex color string to UIColor with Format?

Accepted Answer

Call `ColorFormatter().format("hexCode")` to get a UIColor; it defaults to black for empty strings or white for invalid inputs, ensuring no crashes in UI code.

Question 4

Does Format support date or time formatting?

Accepted Answer

No, Format does not include date or time formatting; you'll need to use Apple's DateFormatter or other libraries for those types, as it's focused on numbers, addresses, and colors.

Question 5

How to handle address formatting in iOS with Format without warnings?

Accepted Answer

For iOS 9.0+, use `AddressFormatter().format(...)` for custom addresses to avoid CLPlacemark deprecation warnings, but note it still has locale limitations and version constraints.

Question 6

Is Format compatible with SwiftUI?

Accepted Answer

Yes, Format can be used in SwiftUI projects for formatting strings and UIColor, but it's primarily designed for UIKit/macOS, so integration might require bridging for some SwiftUI-specific types.
