I’m a bit confused about the practicality and support for Umbrella frameworks in iOS. I’ve read that they’re not supported, but I’ve come across a few tutorials where people are developing Umbrella frameworks. Can anyone provide some insight on this?
I’ve read that they’re not supported
I think it comes down to your definition of umbrella framework. Apple uses the term in a very specific way that I think runs counter to the external usage. So, I’m going to address this as if you asked about nested frameworks, that is:
Create framework A.
Create framework B.
Add a Frameworks directory to B.
And then place A inside it.
That’s supported on macOS but not on iOS. We are clear about that in Placing Content in a Bundle, which says:
iOS and tvOS support frameworks and Swift system libraries at the topmost app level; a nested bundle, like an app extension, can’t include a framework.
Regarding these third-party tutorials, it’s hard to say what’s going on there without a specific example. It’s possible that they are using a different definition of umbrella framework from the ones I’m familiar with.
