Add spell checking

I do all of my writing--almost none of it technical--using markdown and, quite often, on my iPad. It would be great if Textastic had a spell checker. I would happily pay for that as an in-app purchase/add-on.

I use TT for write whatever I need instead of any other write app and I really need spell checker (Spanish and English)

I'm blown away that Textastic doesn't have a spell checker for OSx or IOS. Makes my intended use for notes I only code infrequently pretty useless.

The ability to spell check the text would indeed be beneficial. Please consider!

major miss! 
spellcheck is essential if you are trying to increase your revenue / market share. 

If vim has a spell checker, surely one could be implemented into textastic. 

Please add spellcheck to Textastic. I love the app, but I cannot use it to take notes because it doesn't flag misspelled words. It would be amazing if we could add dictionaries, even custom dictionaries, in the #Textastic folder. 

I just have to throw my request in with the others. At this point I’m doing all of my composing and then having to copy/pasta my work into another source to ensure that it’s not embarrassingly misspelled. Anything you could do to help would be great!!

Would like better spell checking support, anything you can do to improve the editor to indicate misspelled words and a spelling dictionary on iPadOS/iOS would be greatly appreciated. Even if we could have a setting to turn it on/off for specific file types. Another cool option if possible would be to pass my document to an AI Agent to allow it to proof my document and return back corrections. I use Textastic mostly for writing just because I think it is great for that. Hence the need for spelling/grammar proofing. Thanks!
