NIB Loading Fix Summary

Problem Identified

Your demo client was crashing with the error:

Could not load NIB in bundle: 'NSBundle .../SwiftWarplyFramework.framework' with name 'MyRewardsViewController'

Root Cause

The issue was that view controllers in the SwiftWarplyFramework were not properly specifying the NIB name and bundle when being instantiated. When your demo client tried to create these view controllers, iOS couldn't find the XIB files because it was looking in the wrong bundle.

Solution Applied

Added proper initializers to all XIB-based view controllers in the framework:

Fixed View Controllers:

  1. MyRewardsViewController
  2. ProfileViewController
  3. CouponViewController

What Was Added:

Each view controller now has these initializers:

// MARK: - Initializers
public convenience init() {
    self.init(nibName: "ViewControllerName", bundle: Bundle(for: MyEmptyClass.self))
}

public override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: Bundle?) {
    super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
}

required init?(coder: NSCoder) {
    super.init(coder: coder)
}

How to Use in Your Demo Client

✅ Correct Usage (Now Works):

// Simple instantiation - uses convenience initializer
let vc = MyRewardsViewController()
navigationController?.pushViewController(vc, animated: true)

// Or explicit instantiation
let vc = MyRewardsViewController(nibName: "MyRewardsViewController", bundle: Bundle(for: MyEmptyClass.self))
navigationController?.pushViewController(vc, animated: true)

❌ Previous Issue:

Before the fix, when you tried to instantiate view controllers without specifying the bundle, iOS couldn't locate the XIB files in the framework bundle.

View Controllers That Don't Need This Fix:

  • CampaignViewController - Uses storyboard instantiation, not XIB files

Framework Structure:

│   ├── screens/
│   │   ├── MyRewardsViewController/

│   │   │   ├── ProfileViewController.swift ✅ Fixed

│   │   ├── CouponViewController/
│   │   │   ├── CouponViewController.swift ✅ Fixed
│   │   │   └── CouponViewController.xib
│   │   └── CampaignViewController.swift (Storyboard-based)
│   └── Main.storyboard

Testing Your Demo Client

After updating your framework dependency, your demo client should now be able to:

  1. ✅ Build successfully (previous podspec fix)
  2. ✅ Run without crashing (this NIB loading fix)
  3. ✅ Instantiate and display all view controllers properly

Example Demo Client Code:

import SwiftWarplyFramework

class ViewController: UIViewController {

    @IBAction func showMyRewards(_ sender: Any) {
        let vc = MyRewardsViewController()
        navigationController?.pushViewController(vc, animated: true)
    }

    @IBAction func showProfile(_ sender: Any) {
        let vc = ProfileViewController()
        navigationController?.pushViewController(vc, animated: true)
    }
}

Next Steps:

  1. Update your framework dependency to get these fixes
  2. Test your demo client to ensure it works properly
  3. All view controllers should now load and display correctly

The framework is now properly configured for CocoaPods distribution with correct bundle references for all XIB-based view controllers.
