Introduction: The Challenge of App Store Submission

When developing an application, one of the crucial steps to take is submitting it to the App Store for review. However, as many developers find out, this process can sometimes become a hurdle, especially if there are issues during the login process in a demo account. In this guide, we will explore a real scenario where the password field was failing to submit correctly and outline how to resolve this issue effectively.

The Problem: Submitting Passwords with ngModel

Wenjie, a developer, encountered an issue during the App Store review process where the Apple review team could not log in using the demo credentials. Upon examining the server logs, it was evident that the password field was not sent to the backend, resulting in a confusing rejection. Local testing didn’t replicate the problem, leading to concerns about data binding between the form and the model.

The login form was set up with the <ion-input> directive, using Angular's ngModel to bind the input fields:

However, despite correctly setting up the model, the password field would not function as intended when submitted.

Understanding the Solution: The Change to Native HTML Inputs

The core issue turned out to be related to the use of the <ion-input> component and data binding associated with it. Wenjie’s solution was straightforward yet effective: he switched from using ion-input to native HTML input elements. This adjustment proved to be the key in resolving the submission issue.

Step-by-Step Change

Update Form and Inputs:
Replace <ion-input> elements in the login form with standard HTML <input> elements. Here’s how the change looks:

Revise TypeScript Logic:
The logic in the login.page.ts file stays mostly unchanged but should also reflect that you are now using form controls. Make sure to create your form group correctly and validate that the password is not empty.

Utilize FormBuilder for Validation:
Continue using Angular's FormBuilder for creating a structured form with validators for required fields, ensuring that validations are handled properly in the code:

Login Functionality:
Ensure the doLogin() method correctly accesses values from the updated form controls:

Conclusion: Ensuring Submission Success

Switching from Ionic’s <ion-input> to native HTML <input> elements resolved a significant roadblock in the App Store submission process. By identifying and addressing the data binding issue, Wenjie could ensure that the password field was properly submitted, allowing the review team to log in without hassle.

If you’re facing similar challenges with login forms in your Ionic applications, consider testing with native HTML inputs. Simplifying the input handling can often lead to a smoother experience both during development and app review.
