</span>NSLocalizedString was designed (in the 1990s) to be used with methods like String(format:…) that take printf-style “%”-substituted format strings.<br>
Swift’s string interpolation is obviously a different mechanism entirely.<br>
<br>
I suspect that Swift interpolation won’t work well for localized strings because the string and the code are so tightly connected. Localization very often needs to change the order of parameters, for instance. It’s also unclear where things like number formatting happen in Swift interpolation; when localizing a string, the conversion needs to be done using the same locale as the string lookup, which might not happen if the string-to-number conversion is separate and uses the default locale.<br>
