As part of her Master’s degree at ETH Zürich, Laura Peer has developed an Android keyboard that solves this problem. The keyboard, called Kännsch, analyzes the text messages stored on the device it’s installed on. Together with a prebuilt database of words that different dialects have in common, this analysis allows the keyboard to accept Swiss German text without wrongly correcting words.
A keyboard extension would not be able to do this on iOS.
