@Jimmy Nelle so i should just wait for it to start working again ? 🤣

[Jimmy Nelle]

Just use xcodes-select and downgrade to Xcode 16.4

[Kashismails]

Thats what i am currently doing hope it works fingers crossed thanks for the heads up

[Jimmy Nelle]

I would also suggest to delete your gradle cache, derived data and restart your MacBook, no joke

[Kashismails]

Thats the first thing i did whenever something goes wrong its mostly derived data thats the culprit

[Kashismails]

Thanks @Jimmy Nelle this worked

[Jimmy Nelle]

Nice
