Linking the project
Open ios/Runner.xcodeproj in Xcode, then add $crate/$crate.xcodeproj as a subproject
of the Runner project. It should look like this:
Click on the Runner root project, then go to the Build Phases tab.
First, expand the Dependencies phase, and add $crate-staticlib
for iOS, or $crate-cdylib for MacOS.
Then, expand the Link Binary With Libraries phase, and add lib$crate_static.a for iOS, or $crate.dylib for MacOS.
