Build works fine on Android but not on iOS

ivosp · September 22, 2021, 6:01pm

Hi, maybe someone can help me here. I build my app with exop build:android/ios and it does it without any errors or warnings. But now when i went and tried testing it on the Android Emulator and my phone the apk works as intended. So far so good. It’s just the ios build that’s giving me grief. both on testflight and on the simulator the app just showes me the splashscreen. No crash or errors. I waited for over an hour and nothing happened. Any ideas are welcome on how to get it running on iOS.

# Stuck on the Splash Screen?

It can be frustrating to work on your app when you can't even get it to load past the splash screen. Here are a couple of possible reasons why you might be seeing this with your app:

### 1. You may have forgotten to call `SplashScreen.hideAsync()`

If you call `SplashScreen.preventAutoHideAsync()` to do some work while the splash screen is displayed (for example, to preload extra data and assets while your app starts up), you need to ensure that you always end up calling `SplashScreen.hideAsync()`. It's possible that you forgot to call this method!

### 2. An error may have prevented `SplashScreen.hideAsync()` from being called

Let's say you structure your code like this:

```js
async function loadResourcesAsync() {
  await loadStoredDataAsync();
  await loadFontsAsync();
  SplashScreen.hideAsync();
}
```

unfortunately even with the SplashScreen.hideAsync(); command in place as the first command after the imports in app.js.
expo start and expo start -i -c --no-dev --minify both work fine.
