I use KeychainSwift to store my user's keychain data using my created iOS app.
The question is:
Where can I see the data it stored?
I already tried going to
Settings -> Password & Accounts -> Website and App passwords
but I can't find my application there.
I'm use an iPhone 6 as my device.
You can work around this using the 3rd party macro/scripting app called "Keyboard Maestro", from http://www.keyboardmaestro.com
Here's a screen shot of the simple script I use. Currently it only works when the App Store is in the background, and gets automatically activated by clicking a web link in Firefox or something, but you get the idea, this could be modified and improved in various ways.
Needless to say, security is compromised by storing your password in plain-text within Keyboard Maestro script, so be sure it's a unique, random password that you don't use anywhere else.
Your Twitter app should not actually have your password stored on your iOS device. Rather it should have a security token, specifically an OAuth access token.
Have you tried resetting your password via SMS?

There's no user interface for this part of the keychain what what is included in the app (or apps) created by that specific developer.
The keychain area that is accessed by the iOS app is specific to that app (or group of apps by the same developer, if specified). It cannot be accessed by other apps, so no App Store app will allow you to show the contents of the keychains of other apps. Nor are the app specific keychains areas viewable through the Settings app or any other first party app.
As a developer, you can add such user interface to your own app - or for debugging purposes simply use the Xcode debugger or add prints to the console with information from the keychain.
The Keychain can in general be synchronized over iCloud with other devices - including macOS devices. This does however not happen automatically for third party apps. The app would need to explicitly asks for iCloud syncing using the kSecAttrSynchronizable attribute.
Even then, the macOS Keychain Access app does not allow you to view all the data stored in the keychain by a third party iOS app.
