Investigate support for SwiftUI

Any update on this ? Really want CurrencyTextField for SwiftUI

[marinofelipe]

Hey @tariq235 👋 , no update yet.
I'll get some time this week to finish my investigations, define a plan and start to work on it.

Hey I hasn't able to focus on it as I wanted the past week.
If anyone already has deeper experience with SwiftUI and want to contribute with ideas on how we can support it on CurrencyText, that would be appreciated :).
I'll most likely only be able to put enough hours into evaluating ways of bringing CurrencyText features to SwiftUI next week or so.

Investigation was done, now moving to the implementation part, #76.

Basically the decision was between two main options, by priority:
1. Vanilla SwiftUI. Would make use of TextFIeld binding and closure properties, integrated with CurrencyFormatter to format the text as currency, from right to left, with same behavior as on CurrencyUITextFieldDelegate:
2. Bridging a custom UITextField subclass via UIViewRepresentable, that would receive a CurrencyFormatter, and use a customizable CurrencyUITextFieldDelegate internally.

I'm confident 1 will work, but further tests must be done to ensure correct behavior. If anything goes south it should be easy and fine to re-route to option 2.
Besides 1 being vanilla SwiftUI, it would also be smaller in size, complexity, and non dependent on UIKit. Let's see how it goes 🤞 .
