The lazily-initialized type does not have a public, parameterless constructor.

Expected Behavior

Voice is starting to pronounce text.

Actual Behavior

App crashes.

Here you can find how the code used.

Looks like the linker is being a bit aggressive. That code was re-architected with a lazy so let me update and get you a nuget to try asap.

I am curious as a workaround if you do something like this in your AppDelegate:

var test = new AVSpeechSynthesizer();

that may keep it linked in.

Thanks for the fast reply. Will be waiting for it 🙂

I've started the build, it may take some time to deploy.

Yeah, with this line it is working now (tested in TestFlight version).

[jamesmontemagno]

Fantastic! yeah, just the linker was removing. We will hot fix it.

Can you remove that line and try out this NuGet -> https://dev.azure.com/xamarin/public/_build/results?buildId=16377&view=artifacts&type=publishedArtifacts

[ilyalehchylin]

This NuGet is working too 🙂

[jamesmontemagno]

Can I bother you to try this one: https://dev.azure.com/xamarin/public/_build/results?buildId=16434&view=artifacts&type=publishedArtifacts

I did a different work around that I think is better. Sorry to keep asking :)

[ilyalehchylin]

No problem, you may contact me as much as you need 🙂

Unfortunately, with this NuGet app crashes. I will check the error.

[ilyalehchylin]

The same error: TextToSpeech error: The lazily-initialized type does not have a public, parameterless constructor.

[jamesmontemagno]

Got it! Let me try one more thing :)

[jamesmontemagno]

Alright, one more for ya to test out: https://dev.azure.com/xamarin/public/_build/results?buildId=16525&view=artifacts&type=publishedArtifacts

[ilyalehchylin]

Yup, it's working

[jamesmontemagno]

YAY! <3 thanks!

[ilyalehchylin]

No problem, I'm glad I was able to help with this issue 🙂

[jamesmontemagno]

Will be in 1.5.3

[nikhildpardasani]

Hi @jamesmontemagno Can you tell us by when can we expect release 1.5.3 ?

[rs-mobitech]

Any estimate when 1.5.3 will be out?

[jamesmontemagno]

We are working on getting it out soon.

For a workaround just add this to your AppDelegate:

var test = new AVSpeechSynthesizer();
