React-native-firebase: 🔥 DynamicLinks iOS: `await dynamicLinks().getInitialLink()` works on debug, but doesn't work on release mode

[noway]

Issue

await dynamicLinks().getInitialLink() works in debug mode, but doesn't work in release mode on iOS, on certain iPhones. Please not that the app does not crash, but rather null is returned by await dynamicLinks().getInitialLink() when it should be returning the dynamic link url. onLink seems to be working fine, haven't noticed any issues with that. It is confirmed not to work on iPhone Xs with iOS 12.4.0 (device) and iPhone Xs with iOS 12.2.0 (Simulator). I use preview page in my links. Tested both from Safari via preview page and from Messages/Notes app, but NOT through App Store. See testing matrix:

iPhone Xs with iOS 12.4.0 (device), debug: not tested
iPhone Xs with iOS 12.4.0 (device), release: ❌ broken
iPhone Xs with iOS 12.2.0 (Simulator), debug: ✅ works
iPhone Xs with iOS 12.2.0 (Simulator), release: ❌ broken
iPhone Xs with iOS 13.0.0 (Simulator), debug: ✅ works
iPhone Xs with iOS 13.0.0 (Simulator), release: ✅ works
iPhone 7 Plus with iOS 12.4.1 (device), debug: ✅ works
iPhone 7 Plus with iOS 12.4.1 (device), release: ✅ works

This issue is critical because it affects a significant amount of the iOS user base, I think it might be affecting any iPhone X and higher users who haven't updated to iOS 13 yet (i.e. everyone but the early adopters) which is a very substantial percentage of all iOS users.

The issue might be releated to https://github.com/invertase/react-native-firebase/issues/1901, and if so the issue has failed at least 2 Firebase customers, who since have chosen to switch to branch.io instead. See https://github.com/invertase/react-native-firebase/issues/1901#issuecomment-469242110 and https://github.com/invertase/react-native-firebase/issues/1901#issuecomment-477839585

Android is working flawlessly as far as I've tested, with getInitialLink, onLink, install through Play Store all working perfectly. Only issue is iOS.

Code I'm using:

  componentDidMount() {
    this.init()
  }

  init = async () => {
    const initialUrl = await dynamicLinks().getInitialLink()
    this.setState({ dynamicLinkUrl: initialUrl ? initialUrl.url : null })
    console.log('dynamicLinkUrl', initialUrl ? initialUrl.url : null)
    Alert.alert('dynamicLinkUrl', initialUrl ? initialUrl.url : 'null')
    await this.authenticate()
    console.log('this.props.user.id', this.props.user.id)
    this.unsubscribeOnLink = dynamicLinks().onLink(this.onLink)
  }

  onLink = ({ url }) => {
    console.log('onLink url', url, Date.now())
    this.onDynamicLink(url)
  }

I am experiencing the same issue..

• I click on a dynamic link, takes me to the appcenter/appstore/testflight.
• I don't click on install, instead build and launch my app in debug/release mode (both work). The app catches the dynamic link's corresponding deeplink on first launch (as the dynamic link is pasted in the clipboard)
• However the app with the same code, on deploying to appcenter/appstore/testflight, doesn't recognise the dynamic link (even though it's in the clipboard at the time of install).
• Another observation is that the clipboard gets cleared off after the launch.
• However, post installation, when the same dynamic link is clicked from notepad, it takes me into the app, resolves its corresponding deep link and works as expected. If I wanted to achieve this I would have gone with a DEEP LINK instead of a DYNAMIC LINK. This issue beats the entire point of Dynamic link as it doesn't serve the purpose of taking me to the intended user activity.

I have the same config as @noway and this is a very valid issue.

[ram95krishh]

Hey @noway.. After a lot of tries, this set up got everything (even first open after install scenario) working for me. Can you check this out and let me know: https://medium.com/@ramakrishnan_89356/firebase-dynamic-links-for-your-react-native-app-ios-setup-only-c6e1f5a7944e

[mikehardy]

@ram95krishh through no power that I actually have, I grant you 10 internet points for writing such an excellent detailed guide for future people :-)

[ram95krishh]

@mikehardy Haha, thanks mate, that means a lot :D

[noway]

This does look like an interesting approach, I gonna need to try it out. Atm we just have broken implementation in production and we remedy it by just trigerring stuff we need on first sign up.

[RWOverdijk]

For me the issue wasn't solved with the code in that article. This is because I was using a custom domain and this hasn't been documented properly.

The solution for me was the default code from the rn-firebase docs and adding the custom domain to the Info.plist file:

  <key>FirebaseDynamicLinksCustomDomains</key>
  <array>
    <string>https://my.custom.domain</string>
  </array>

[noway]

@RWOverdijk I have this in my project and I still experiencing the issue. This is not just a configuration error, the link works from cold start in iOS13 just fine, the bug seems to be present only on iOS12 for devices without home button.

The most promising workaround so far seems to be using Linking.getInitialURL() alongside firebase.links().getInitialLink()

[RWOverdijk]

@noway Pretty sure that's not the case. Have you followed all the other steps? (capability and links in info).

Also, you need a release build (disable debug in build settings).

Update: Linking will work if you forward the results. But this will give you the short url (if you use those) which doesn't help.

[noway]

@RWOverdijk yes I have followed capability and Info.plist steps. It works for me on iOS13 in release mode on App Store, but does not in iOS12. This is clearly not a configuration issue?

[RWOverdijk]

It works for me on iOS 12 so I think it might be. But I did write a lot of native code for other parts, too.

Maybe your version of React Native is in need of an update? Or maybe I just did something else to make it work and I don't know what. 😄

[noway]

I'm using 0.60.5 as specified in the Environment section of this issue.

[ram95krishh]

@RWOverdijk Thanks for pointing that out.. :)

[alittletf]

@noway you ever get this solved? Im still struggling with getInitialLink not working on iOS. Android works perfect. onLink works perfect on iOS. its just getInitialLink on iOS that wont. I am on RNF 6.3.4 (latest) and RN0.61.4

[noway]

@alittletf we just stopped testing for iOS12

[Nehal-29]

@alittletf Did you find any solution to this? Facing the same issue

[AkeleyUA]

I don't know why, but if I manually build main.js and then try to use getInitialLink, it starts working. As a workaround. just an observation.
