Using External Accessory Framework in iOS App Development with MAUI

Hello, Apple Developer Community,

I am currently developing an iOS application using .NET MAUI. In this application, I need to use the ExternalAccessoryFramework to communicate with external devices.

However, I couldn't find any information about the compatibility of MAUI and ExternalAccessoryFramework, and I would like to confirm whether this combination is possible.

  1. Can an iOS app developed with MAUI use the ExternalAccessoryFramework?
  2. If so, could you provide any guidelines or reference materials about its implementation?

I would greatly appreciate it if you could share your knowledge and experience. Thank you in advance.

I recommend that you ask this question via the support resources for you third-party tooling.

From Apple’s perspective, the External Accessory framework is the same as any other Objective-C framework. If your tools can use an arbitrary Objective-C framework, like Swift can for example, I would expect this to work. If they can’t, the vendor should be able to explain how to do that manually.

Share and Enjoy
