Enlarging keyboard for IOS users

Thank you for allowing the return of Swiftkey for IOS devices. I am not sure if there was ever a way to enlarge the keyboard for IOS devices like they had for Android users but I cannot see a setting for keyboard enlargement like android had on my iphone. If there never was a setting to enlarge the keyboard for IOS then when Microsoft adds there changes to this new Swiftkey upgrade, can you install a feature to do so please. I am sure i speak for many of us Swiftkey users. Thanks!
