# multiplatform

I’m making a simple break timer app.
After playing around with swing for deskop I figured out that it wasn’t powerful enough on macOS, especially regarding windows management.
So this is the ideal targets of my app:
• Android -> Compose multiplatform
• Windows -> Compose multiplatform
• Linux -> Compose multiplatform
• iOS -> Native UI with shared kotlin business logic
• macOS -> Native UI with shared kotlin business logic
To build the iOS and macOS apps I decided to go with the multiplatform target in Xcode, which targets iOS, ipadOS and macOS all at once.
Using cocoapods in a Xcode multiplatform project is not supported yet so I need to use Swift packages (xcFrameworks), which seems to be buildable from the native.cocoapods plugin already.
Now with that out of the way, what should my project structure look like?
I don’t like putting the shared compose UI for android/windows/linux inside the shared module because that would get included in the swift package too and it’s not needed.
Any suggestion is appreciated!

FIgured out it might not be the best decision to create a multiplatform project with xcode as it might be hard to create the related submodules in shared for the expected/actual mechanism. Or is that possible by configuring two submodules shared/iosMain and shared/macMain ? Would they get compiled correctly in the xcFramework?

Just create another Gradle module consumed by the compose targets.

[Giuliopime]

Not inside the shared one right, a standalone one?

[hfhbd]

Yes. Just to mention, I talk about Gradle modules, not Xcode (broken by design) modules.

[Giuliopime]

yeah ofc

[Giuliopime]

Any opinion on the multiplatform xcode setup?

[hfhbd]

I never used the cocoapods plugin but the xcframework which does work very well with Kotlin Multiplatform and Xcode multiple targets.

I believe xcframework builds all architectures every time, which is pretty slow for development. You could try the regular integration via embedAndSignAppleFrameworkForXcode Gradle task. This should build only the current architecture.

[Giuliopime]

Yes I would only use that for deploying in prod, also if I don't change the business logic much it wont be a big issue

Which features do you lack in Swing for WM?

[mikehearn]

(there are libraries that add some missing features)

[Giuliopime]

On macos it's not possible to open a window above other full screen windows with swing

[Giuliopime]

That's the main issue

And it's just a plus for me to make a native app because I can manage timers for native apis like background tasks, instead of having a simple coroutine
