Hi! I'm trying to do the compose multiplaform starter thing, just to learn stuff, and I can't get my iphone app to fire up 😞

All I get from the IDE is this error, I do have an iphone simulator up, so it got part of the way there. Any advice?

[beepdog]

I do have xcode 16+ installed, I was able to fire up the simulator. I did launch Xcode once to make sure that runs.

I am able to build the binaries:

it's something to do with the running of it

[David Nedrow]

Hmmm. Android Studio or IntelliJ? Also, how are you attempting to run the app? From the terminal? Or a run configuration?

[beepdog]

Android Studio, from the run configuration just like the tutorial shows 🙂 I wasn't sure how to run it from the terminal, tbh, I haven't gotten that far in any tutorials, and no gradle task jumped out at me yet.

[David Nedrow]

Be sure that you are linking the built iOS framework in the Build Phases.

Are you able to run the app via Xcode?

I started a project from scratch and basically got the same thing you did when I tried to run the app from Xcode. I added the framework (called ComposeApp.framework here) and then I was able to run the app from Xcode.

Still having an issue with running from AS. I'll play with it some more.

I don't know how to do anything on iOS, I only have a macbook through work, so this is baby's first iOS app, and I know next to nothing about xcode 🙂

If I open xcode, will it be reasonably easy to figure out? And I'm gonna head home so no more Apple Computer debugging 😞

[David Nedrow]

Heh. It's relatively straightforward.

[beepdog]

I opened the iosApp folder in xcode, and it didn't complain too much. I hit the Go button on it, and there's a spinning iphone simulator thingy

[beepdog]

oh it worked!

[beepdog]

well kinda

[beepdog]

the app showed up, but it's empty

[beepdog]

AH, it just took a while and it cause the iphone to restart?

[beepdog]

this is a rollercoaster

[beepdog]

welp, it can wait until tomorrow anyway. I got something to happen, so that's nice

[beepdog]

well that was quite strange, but it did work eventually

[beepdog]

good enough for me at the moment

[beepdog]

Thanks for the advice

try to install newest kotlin multiplatform plugin beta. it includes kdoctor which tries to find issues with your setup. a blog post went out today (the 19th) about it.

also ask in #C0346LWVBJ4 maybe for some more ios specific folks
