Is there anything in the SKIE template that would interfere with adding other XCFrameworks to the iOS testapp? As far as I can tell I'm building my other XCFramework correctly, but getting errors like it can't find / process it

[kpgalligan]

By "other XCFrameworks", are these other Kotlin XCFrameworks or just other XCFrameworks? What's the error? Where are you seeing it?

[kaeawc]

Not a Kotlin XCFramework - this is created from Rust UniFFI headers and a Rust library.

Here's the errors I'm seeing in XCode build log:

I'm going to try to make a repro in an ios project without kmmbridge template stuff and see if I can learn from that

[kaeawc]

The reason I'm asking is because I see there are some custom settings for XCFramework search path in the XCode Build Settings for my target that point to the allshared framework

[kpgalligan]

They're all just saying it can't find the binary for those symbols, which are presumably from rust. Presumably the rust code is compiled and available somewhere. How is that distrubuted?

[kaeawc]

Basically following this https://forgen.tech/en/blog/post/building-an-ios-app-with-rust-using-uniffi but its strange that they used uniffi bindgen on the .dylib file instead of the .udl which specifies what to expose... the official uniffi docs say to use .udl with bindgen.

Figuring it out

[kpgalligan]

Essentially, the error says it can't find the binary. I skimmed that post. If you're following that directly, then you used the "drag and drop" approach. If so, for some reason, the build sees the headers but not the binary. Generally that means something is wrong with either the linker settings not referencing the framework, or the framework search path not pointing to wherever the framework is. However, if it found the headers, then I'm not sure. I generally avoid the "drag and drop" approach for external frameworks when possible. A screenshot of your Xcode navigator (the project tree on the left), and your build settings for the iOS target, might help.

I got this working and… I don’t know what I was doing wrong. I am going to document the working process though.

Welcome to KMP. I made you this.
