.NET MAUI iOS Release Build Requires Developer Mode to be Enabled on Physical Device

Question

I have developed a .NET MAUI iOS application and successfully created an .ipa file using a release certificate and provisioning profile. However, when attempting to install the app on a physical device, I encounter the following error:

"This app requires Developer Mode to run."

Answer 1

Hello,

However, when attempting to install the app on a physical device, I encounter the following error

Please go to Settings > Privacy & Security > Developer Mode and tap Developer Mode to turn on.

You could try to install the app via TestFlight to see if the issue still exists.

Also, this prompt means the risks of installing development-signed app. Please make sure the certificate and provisioning profile are type of Distribution.

For more details, please refer to Publish a .NET MAUI iOS app for App Store distribution - .NET MAUI | Microsoft Learn

but my issue is that why it is asking me to turn on developer mode even if the app is signed with the distribution certificate and profile.

It's a prompt from Apple and it's the limit to test the app on your physical device. See Enabling Developer Mode on a device | Apple Developer Documentation

And moreover my experince with VS code for mac for maui development is terrible , I wish VS for mac still existed!!

VS for mac has been retired. If you have any issue with VS code (c# dev kit), you could report it at https://github.com/microsoft/vscode-dotnettools.
