The new gender neutral emojis differ slightly from the male and female ones.
In some, the style and color of their clothes is changed. In others the haircuts are different and a "gender neutral facial structure" is used, says the Emojipedia website.
The attempt at on-screen inclusivity has not pleased everyone however, with some suggesting the icons indicate how gender-nonconforming people should look.
"How do u determine that these emojis are how gender-neutrality should be represented or that these emojis even represent most gnc people," wrote one Twitter user. "I don't understand why they weren't just all neutral to begin with," wrote another.
"Regular old smileys were neutral. I don't know why we had to go and start gendering everything in the first place."
When it unveiled the designs earlier this year, Apple said they would "bring even more diversity to the keyboard" and "fill a significant gap" in the selection of emojis.
"Users will now be able to select any combination of skin tone, in addition to gender," it said.
Apple also serves up some niche offerings in the new update including a plate of falafel, a skunk and a banjo. Businesses have paid increasing attention to becoming more inclusive in recent times. Toy maker Mattel for example released gender-neutral dolls last month with none of the curves or large muscles of the traditional Barbie or GI Joe, while many small fashion brands and make-up companies are marketing non-binary products.
