Touch ID not showing StoreKit

Question

I'm using StoreKit for processing In-App purchases, which works perfectly. My only issue which I couldn't find a solution online is:
In other apps when trying to do an IAP, I'm asked for Touch ID (so it's not my device set up wrong or so) while in my App it always asks for password. How can I get Touch ID to work for authentication with iTunes? Thank you in advance!

Alright,
So I'm not sure if this is always the case but in the AppStore version of my App you can actually use Touch ID.
Maybe Touch ID is just not supported when developing... Still a bit confusing that they have you release your App without being sure if Touch ID is going to work :/
