Thanks for this tutorial.
Generally what we are doing is that first add some languages to keyboard by going to settings>general>keyboard settings>add new languages and then we can change keyboard languages from our app by using globe icon. This languages are only those which we have added into our keyboard manually.
Now, I have created one app in swift. In this app there is 10 buttons denoting different languages. On button click, if the language is not added from settings then i want to programmatically add languages into keyboard without going to device’s settings app. Anyone having idea about this, Please?
