Apple's best current case for coding agents in Xcode may have very little to do with writing app logic. What's new in Xcode

It may be localization. Localizing your app using agents

That sounds less exciting than "build my feature for me," but it also sounds more believable.

Apple now documents a pretty concrete workflow here: agents can add languages, update string catalogs, translate strings, and help with language-specific plural variants. Apple also says Xcode can build all targets to collect localizable strings and can localize human-readable text in your app's information property list. Localizing your app using agents

That is the part I find interesting.

This is not Apple presenting agents as magic. It is Apple attaching them to a job that is repetitive, bounded, and reviewable. What's new in Xcode Translate your app using agents in Xcode

If you are an indie developer, localization is exactly the kind of work that tends to slip. It is important. It can help you reach more markets. It is also easy to postpone because it feels like a side project until the week you wish you had already done it. Localization

Apple's newer guidance makes the workflow sound more operational than aspirational. The company says you can give agents translation guidance through files such as AGENTS.md or CLAUDE.md, ideally by pointing them to a separate TRANSLATION.md with glossary terms, untouched product names, or tone guidance. That makes the output easier to steer instead of treating translation quality like a mystery. Localizing your app using agents Translate your app using agents in Xcode

The limits matter too.

Apple still recommends reviewing the results, checking right-to-left layouts, and getting feedback from people who actually speak the language and live in the region you want to support. That is the right level of ambition. An agent-generated first pass is useful. Blind trust is not. Localizing your app using agents

That is why this feels like one of the more practical Xcode 27 agent stories so far.

Not because it replaces judgment, but because it might remove enough tedious setup to make localization happen earlier and more often.

For a lot of small Apple apps, that is a better use of AI than another autogenerated view file.
