Resolving the Mac Version Resizing Issue for Universal Apps: A Practical Guide

If you’re a developer transitioning your application from iPhone/iPad to MacOS using Mac Catalyst, you may encounter an unexpected issue: the app window doesn't resize properly when it’s downloaded through TestFlight. Developers often assume that resizing capabilities come "for free," as promoted in various resources. However, some users discover that their Mac app seems stuck in one size, allowing for corner dragging but maintaining a constant window dimension. Let’s delve into this issue, explore the root cause, and outline clear solutions.

Understanding the Problem

You might be confused if your application resizes appropriately in Xcode but not when installed via TestFlight. Here are the main points to consider:

The app has been built to support MacOS using Mac Catalyst.

Resizing is functional when directly tested from Xcode.

The app is currently live on TestFlight, but resizing is not effective during this installation.

It’s important to diagnose whether the issue is stemming from incorrect version downloads or potential configuration pitfalls related to navigation controllers, like SideMenu.

Identifying the Root Cause

During the troubleshooting process, the resolution surfaced from a common oversight. Many developers may not realize they are installing the iOS version of the app on a Mac rather than the intended MacOS version. Here’s how this can happen:

Switching between Versions: When using TestFlight, there might not always be a visible toggle between the iOS and MacOS versions, and this can confuse users during the installation process.

Installation Confusion: It’s easy to overlook the version switch, particularly if you are unfamiliar with the TestFlight interface and the presence of multiple builds.

Solution Steps

To ensure your Mac app is functioning as expected and taking advantage of the resizing feature, follow these steps:

1. Verify the Version in TestFlight

Make sure you are downloading the MacOS version:

Open TestFlight on your Mac.

Look for the version toggle at the top of the app.

Ensure it is set to use MacOS rather than the iOS version.

2. Test Your Build

After toggling the version switch:

Install the MacOS version of the build that includes SideMenu and ensure it works as intended.

Verify if resizing operates correctly by dragging the corners of the app window.

3. Troubleshoot Further If Needed

If issues persist:

Remove the iOS version from your Mac before downloading the MacOS version to avoid confusion.

Check if any window size restrictions are set that may affect resizing. This might involve looking into your Window scene configurations.

4. Rinse and Repeat

If resizing still does not function optimally:

Consider conducting another build.

Modify navigation controllers/settings if necessary, and keep testing through TestFlight until satisfied.

Conclusion

The root problem behind the resizing issue when using a universal app on Mac relates to the accidental installation of the iOS version instead of the intended MacOS version via TestFlight. Ensuring you have the correct version will facilitate the resizing functionality. By following these practical steps, developers can seamlessly enhance the Mac experience for their users, ensuring robust functionality across all devices.

Stay aware of the settings in TestFlight and continue to test your builds for inherent functionality. Your users will appreciate a polished, fully-resizable Mac app experience!
