Project description:
"Senior iOS Developer to Fix RevenueCat & Natively In-App Purchases (Last Bug Before App Store Submission)

Job Description:
Project Summary:
I have an iOS app built with Firebase Studio and the Natively platform. The app is complete and has been approved by Apple for review, but it was rejected under Guideline 2.1 (App Completeness) because the in-app purchases are not working. I have identified the root cause: Natively does not properly support the required StoreKit bridge for in-app purchases.

I need a skilled iOS developer to fix this specific issue. This is the very last hurdle before I can release the app.

The Problem:
When a user tries to access the subscription offering, the app returns a "Cannot Fetch Offering" error.

The app uses RevenueCat for subscription management.

The build was created using the Natively platform.

The App Store has approved the app for review, but the IAPs fail on a live device.

Based on feedback from Natively and my own troubleshooting, this is an integration issue where the Natively build is missing the necessary "bridge" to properly communicate with Apple's StoreKit framework for in-app purchases. The issue is not with the RevenueCat or App Store Connect configuration itself, but with how the Natively platform builds the app.

What I Need You To Do:
I am looking for an expert who can do the following:

Access the project files (I will provide you with secure access to the necessary code and files from Natively, Firebase, App Store and RevenueCat).

Diagnose and implement the fix to enable the StoreKit bridge and resolve the "Cannot Fetch Offering" error.

Test the fix thoroughly on a physical device using a sandbox tester account to ensure purchases work.

Create a new build with the fix and provide it to me.

Guide me on the final steps to get the app approved by Apple, including preparing and submitting the new build with the working in-app purchases.

What I Do NOT Need:

I do not need you to rebuild the entire app.

I do not need you to give me lines of code to type in. I need you to handle the entire technical process of the fix.

Required Skills and Experience:

Expertise in iOS development and StoreKit.

Proven experience with RevenueCat and fixing "Cannot Fetch Offering" errors.

Familiarity with no-code/low-code platforms, specifically Natively, is a significant plus.

Experience with app submissions and resolving Apple's Guideline 2.1 rejections.

Budget:
This is a small, well-defined bug fix project. I am looking for a reasonable fixed price for the entire task. Please provide your proposed fixed price in your application." (client-provided description)
