Hello, is the KMP toolchain compatible with xcode 16 and the latest mac os release?

[François]

The new concurrency feature is not compatible, so no swift6 for now

[François]

use xcode 16 but stay with swift5, you can enable new concurrency as targeted for showing warning instead of error

[Rene Gens]

Cool, thanks, will try it out then

[Rene Gens]

Although it worked, today without changes it started to fail with this message, do you have any idea?

[François]

which version of kotlin are you using?

[Rene Gens]

2.0.20

[Rene Gens]

If I install xcode 15 and make it the default it works

[François]

oh, it’s a KMP compose app, not a SwiftUI/UIKit app, I need to check something

[Rene Gens]

yes

[François]

the project from the wizard is running fine, which one of your iOSMain dependency is not working,
Try at least a basic project to see if there something wrong

[Rene Gens]

Alright, will investigate further.

[François]

Don’t forget to clear all your cache kotlin and xcode

[Rene Gens]

Already have done that

[Illustrator]

Any updates on this, did you successfully made it work?

[François]

update your SKIE to the rc version

[Tadeas Kriz]

Yeah, we're almost ready for a final 0.9.0 release and the latest RC should be well stable for most folks

[Illustrator]

Great. Thank you guys
