React-native-reanimated: Unable to run Example App

[derwo]

Description

I'm unable to run the Example App in neither iOS device or simulator.

Steps To Reproduce

1. Clone repo
2. cd Example
3. yarn install
4. cd ios && pod install && cd ..
5. react-native run-ios
6. Got a compile error
7. Changed Bundle Identifier through XCode
8. Give up using react-native run-ios since it still gives errors
9. Run react-native start and build through XCode
10. App installed correctly
11. Click on any example
12. App crashes:

I've noticed that most but not all of the 1.x version examples works.

Expected behavior

The Example App should not crash.

Actual behavior

The Example App crashes as soon as I open one of the examples.

Snack or minimal code example

Using the latest commit

Package versions

(from the Example App)

• React: 16.11.0
• React Native: 0.62.2
• React Native Reanimated: 2.0.0-alpha.1

Can also confirm I can't get the example app to run on the v2 examples. Tried going back to initial V2 release commits from ~10 days ago, and still no luck.

In the meantime, if you are just trying to get your toes wet with v2, you can use the reanimated 2 playground app and just paste in the code from the Example app that you want to try out. They seem to work just fine. https://github.com/software-mansion-labs/reanimated-2-playground

I tried it 11 days ago and this was working for me, though I had to go up to root folder and install package first

The Example app uses master branch. Lately, there were few PRs with dependencies on each other.

If you want to give a try to Reanimated, it's better to use playground repo which uses the latest stable release.

@CyberMew could you explain what you mean by go up to root folder and install package first? Do you mean to just run npm install in the root directory...?

@terrysahaidak I assume you're referring to this playground repo? After a fresh clone/npm install/pod install, I get what may look to be the same error as @derwo which I put in this gist. I want to help but I have no idea how to work with native backtraces like this.

Xcode version: 11.2.1
...(fresh repo running at 2.0.0-alpha.1, gesture handler ^1.6.1, etc)

[derwo]

@drewandre I had no issues running the playground repo

The "Developer menu" is not showing up.

@terrysahaidak Can confirm the developer menu is not showing doing a standalone install, and the playground app is also crashing for me.

Followed the instructions. That's all.

Running on iOS 12.4 simulator. Not sure if that should makes a difference.

@arberK @nextriot The developer menu not working is probably related to a bug in Xcode/iOS and/or react native 61+ and is already opened here: https://github.com/facebook/react-native/issues/28552

I dont think so. I followed instructions to integrate reanimated 2 in my existing project and the developer menu stopped showing up. I then deintegrated reanimated 2, and the developer menu is showing again.

Same for Example Playground App.

Im on iOS 13.5.1. react-native: "0.62.2".

It seems to be related to the Turbo modules integration.
Removing the following line enables the menu again.

RCTEnableTurboModule(YES);

Here is the fix for dev menu:

I believe this issue is resolved, so I'll close it.

If that's not a case please comment.
