What happened?

I just set up tuist for the first time. It’s a great project, so thank you for creating and maintaining tuist.

I just tried to generate a test project of each type to look at the project structure and what tuist generates.

I ran into issues when generating watchOS and visionOS projects. Nevertheless, both projects build when running tuist build. However, launching the watchOS project in a simulator fails while launching the visionOS project succeeds.

If it helps, I installed mise using homebrew and I am then installing tuist using mise.

Thank you in advance for looking into this!

How do we reproduce it?

For watchOS:

mkdir tuist-watchos

cd tuist-watchos

mise use tuist

tuist init --platform watchos

tuist build

open TuistWatchos.xcodeproj

Then run the simulator.

For visionOS:

mkdir tuist-visionos

cd tuist-visionos

mise use tuist

tuist init --platform visionos

tuist build

open TuistVisionos.xcodeproj

Error log

For watchOS, I get the following error during tuist init --platform watchos:

› tuist init --platform visionos

We received an error that we couldn't handle:

Running tuist init --platform visionos throws a similar error as for watchOS:

In terms of the build errors, it seems that some keys were missing from the Info.plist:

Firstly, either WKWatchKitApp or WKApplication needs to be set. WKWatchKitApp is for WatchKit 1 which is not longer supported, WKApplication is for WatchKit 2 and should be set to true.

"WKApplication": true,

Secondly, the manifest needs to be define if the app is watch-only or if it has a companion app and whether it can run independently of it.

If it is stand-alone:

"WKWatchOnly": true

For a companion app:

"WKWatchOnly": false,

"WKRunsIndependentlyOfCompanionApp": true / false,

"WKCompanionAppBundleIdentifier": "io.tuist.TuistExample"

For a companion app, the watchOS app bundle identifier also needs to be prefixed with the companion app’s bundle identifier. In this example, the bundle identifier would need to be something like io.tuist.TuistExample.watchosapp.

Shall I create a PR to integrate those changes into the watchOS project generator?

Yes, that would be greatly appreciated 🙏 Let us know if you need any pointers, but your suggestions look like a good way forward.

i had no issue in xcode 15.4 and in xcode 16 i again have issue: “WatchKit app being installed is missing either the WKWatchKitApp or WKApplication key”

Hi, @gfmio. I’m Dosu, and I’m helping the tuist team manage their backlog and am marking this issue as stale.

Issue Summary:

  • You reported errors when initializing watchOS and visionOS projects with Tuist, specifically missing “Assets.xcassets” and required Info.plist keys like WKApplication and WKWatchOnly.
  • These missing keys cause watchOS apps to fail launching in the simulator.
  • You identified the necessary Info.plist keys and suggested updates to the watchOS project generator.
  • A maintainer encouraged you to submit a PR to address these fixes.
  • Another user noted the issue persists in Xcode 16 but not in 15.4.

Next Steps:

  • Please let me know if this issue is still relevant with the latest version of Tuist by commenting here.
  • If I don’t hear back within 7 days, I will automatically close this issue.

Thanks for your understanding and contribution!

Hi @pepicrft, the user @CodeWithShreyans has confirmed they are still facing the watchOS and visionOS project initialization issues with missing Assets.xcassets and Info.plist keys. Could you please assist them with this?

pepicrft Sep 30, 2025

@CodeWithShreyans any chance you can share a project where we can reproduce this? Something you might want to do is to create a project through Xcode with a similar setup and compare both side by side to see what the differences are. Once we understand what those are, we can look into setting them automatically for convenience, or document them somewhere.
