Xcode spell checking

Question

Just wondering if there is a way to enable spell checking in Xcode. Maybe an add-on or something...

Answer 1

In Xcode 4.5 you need to choose: Edit -> Format -> Spelling and Grammar -> Check Document Now (cmd + ;)

Answer 2

As of Xcode 11 (tested in 11.3.1), if you turn on "Check spelling while you type", found in the Edit->Format->Spelling and Grammar menu, Xcode will display the red word spelled wrong indicator for comments as they are spelled wrong. It will also spell check camel case identifiers (much to my surprise). I am only just now using this so I don't know the sharp corners but it is exciting. As someone that is bilingual, I find myself mangling words. You can also set the preferred language using the "Show spelling and Grammar" option.
