iA Writer for iOS includes iA’s signature Syntax Highlighting feature.
Enable Syntax Highlight
On iOS devices you can enable (or disable) Syntax Highlight via:
|AA menu||Show Syntax|
|Settings pane||Editor → Syntax: Enable All|Last Used|
|Keyboard shortcut||⇧ ⌘ D|
Parts of Speech
You can specify which parts of speech are highlighted by selecting/deselecting options found in Settings. For example in the Settings shown below you can see Nouns and Verbs are selected:

Syntax Highlight also works well in conjunction with Focus Mode allowing you to see your structure down to sentence-level:
Syntax Highlight leverages system-level libraries and is available for documents/text in the following languages:
Working With Syntax Highlight
There is no right or wrong way to work with the feature enabled. Different writers all have different needs and workflows. Since Syntax Highlight can be quickly toggled using ⇧ ⌘ D you can easily switch from working with Syntax Hightlight to not.
Importantly, Syntax Highlight does not make any changes to your content and you’ll never see the parts of speech highlighted in Preview, printed or exported documents.
If you are not familiar with iA Writer yet, you can check out Style Check, a similar feature to Syntax Highlight providing you suggestions to improve your text.
