Microcharts breaks on iOS 13.3.1

[hunterbrodie]

After updating to iOS 13.3.1, microcharts on my application stopped showing. I tested this with another phone as well, and the iOS update broke it on that phone too.

I'm running it inside of iOS 13.3. This is my first time to use the library but the basic example works for me. Is it still not working for you?

[yesmeco]

I have updated to iOS 13.3.1, since then I have performed the same issue the charts are not showing.

[hunterbrodie]

Sethom it works in 13.3, but not 13.3.1 for me

[dammanjit]

did you get any solution? I am facing the same problem.

[hunterbrodie]

I have not found any solution

[triskacik]

I'm experiencing weird behaviour because the chart is showing properly in simulator (iOS 14.0) but it doesn't show anything on my device (iOS 13.3), maybe it is the same issue. I'll try to update to 14.1 on my device and maybe it will work, I will add the result later

[triskacik]

So it apparently works after the update to iOS 13.4.1.

I believe the issues you guys are experiencing are likely linked to the "device specific builds" setting, see my bug report here: https://github.com/dotnet-ad/Microcharts/issues/217

I couldn't get the charts to render on iOS, unless I disabled the "device specific builds" setting. I also made sure to enable "Link Framework SDKs Only" for all configurations (not sure it's needed, but I think enabling this setting makes sure 3rd party frameworks like Microcharts are integrated into the project).

I've tried what @wolf81 suggested but no success. The application crashes when start with this message in Visual Studio: 2021-06-11 16:56:09.320 Xamarin.PreBuilt.iOS[11880:738685] Xamarin.Forms AppDelegate name: AppDelegate

[eman1986]

Are you sure it's the library? Have you removed it?

[Rabosa616]

Yes by removing the library I do not have any problems at all

[Thwar]

Any update or workarounds for this? Android emulator runs fine but on IOS the app does not start. I get the same error as Rabosa616.

[eman1986]

if I had a good test case brought to me someone could try to reproduce it.

[Thwar]

I believe it has something to do with the latest IOS version (14.6) or device?. I created a brand new shell project and just implemented the chart example.

Running on Iphone 7 with IOS 14.3 I had no issues. Chart was showing flawless. However running on an Iphone 11 pro max with IOS 14.6 and IOS 14.7.1 (updated recently), the app gets stuck on the splash screen and crashes.

Using Microcharts.Forms 0.9.5.9
