modernbanc-ios
Modernbanc iOS is an official Swift library you can use to securely collect sensitive data from your users and store it in Modernbanc's encrypted vault.
Installation
You can install this library via the Swift Package Manager.
Usage
This library contains a ModernbancTextfield component that you can embed into your app. Because it extends a native UITextfield component you can style and customize it to your liking.
To use it initialize a Modernbanc API client and then pass it to the textfield.
let client = ModernbancApiClient(api_key: "Your api key, ensure it has permissions to Secrets functionality")
let input = ModernbancTextfield(client: client)Once the user has entered the details you can create a secret from the value in the textfield.
func tokenize() {
input.createSecret(completionHandler: { (result: Result<CreateSecretResponse, MdbApiError>) in
switch result {
case .success(let response):
let secret = response.result.first
print("Successfully created secret: \(String(describing: secret))")
DispatchQueue.main.async {
self.label.text = "Secret id:\(String(describing: secret?.id))"
}
case .failure(let error):
print("Error creating secret: \(error)")
}})
}We prevent you from accessing textfield's raw text but if you want to validate the input you can use our validationFn in the following way:
func isLongerThan5Characters(text:String?) -> Bool {
return (text?.count ?? 0) > 5
}
input.validationFn = isLongerThan5Characters
input.text = "Hello world"
print("Value is currently valid \(input.isValid)")
Demo app
To run the demo app, open ./demo-app/demo-app.xcodeproj and ensure you've created a Constants.swift with below content:
public let mdb_api_key = "The api key you can get from Modernbanc UI"
