I have a static library (.a) compiled with LDC for iOS

its classes and methods. Do I need to do some additional
configurations?
When you say "IDE", I'm going to assume you're referring to
Xcode. Xcode has absolutely no support for D at all.
Since the Objective-C support in LDC is so limited I would
recommend creating `extern(C)` functions in the D code, which
forwards to your D functions (or have the functions being
`extern(C)` to begin with). Then you need to have these
declarations available in a C header file, either created by
using the `-HC` flag or by manually writing the declarations.

Thank you! We did it as you said and it works.
And thanks a lot for the iOS support, it's amazing!
Few notes on our finding, maybe it will help someone.
--- About header files:
We had to use DMD to create .h files. Couldn't find a way to get
them via ldc, which seems to only generate .di files (probably
just missing something).
In the end, we are using the compiled D library from Flutter
Dart, writing pointers to symbols manually.
--- About compiling for iOS simulator:
When compiling druntime and phobos for iOS simulator, you need to
add -mios-simulator-version-min=12.0 flag to --cFlags, here is an
example:
ldc-build-runtime --ninja
--cFlags="-mios-simulator-version-min=12.0;-target;x86_64-apple-darwin" --dFlags="-mtriple=x86_64-apple-darwin;-fvisibility=hidden" CMAKE_SYSTEM_NAME=Darwin BUILD_SHARED_LIBS=OFF
(More info: https://wiki.dlang.org/Building_LDC_runtime_libraries)
And you have to link phobos and druntime static libraries (.a)
files to Xcode, not just your library.
