Daily Local Notifications Are Not Working

Look at the comments within the code

I got it working with the help of this video: https://www.youtube.com/watch?v=mG9BVAs8AIo

and some code from @lorem ipsum thank you so much for the help

Add one day in today's date so we got next day and then add your specific time on which you want trigger the notification.

var triggerComponents = DateComponents()

let nextDay = Calendar.current.date(byAdding: .day, value: 1, to: Date()) ?? Date()
triggerComponents = Calendar.current.dateComponents([.year, .month, .day, .hour], from: nextDay)
triggerComponents.hour = 14
