Xamarin.Forms [Bug] Xamarin forms app crashes for Arabic in iOS 16 in production : High priority issue

Description

Xamarin forms-based application crashes in iOS 16 beta for Arabic languages when there is a new line character in the string

If the device is set to Arabic language and there is an Arabic localization entry, such as ar in info.plist or lproj, Xamarin-based applications crash in iOS 16 Beta.

Example 1 :
<data name="some_key" xml:space="preserve">
    <value>هذا الإصدار من نوع ألفا!
.استخدام هذا التطبيق مخصص لغرض الاختبار فقط
</value>
 </data>

Used resx in XAML file like below

<Label HorizontalTextAlignment="Start"
           Text="{localization:Translate some_key}">                                  
</Label>

Also, it will crash if we apply "\n" in the code when binding to XAML file. Example 2 :

<Label HorizontalTextAlignment="Start"
            Text="هذا الإصدار من نوع ألفا! n\
.استخدام هذا التطبيق مخصص لغرض الاختبار فقط">                                  
</Label>

We tried with Environment.NewLine in the ViewModel part and binding the text to XAML then also it is crashed

Steps to Reproduce

Pre conditions: ar should be added in info.plist Localizations array entry

Set Arabic language as device language
Lunch the app which has the above code
App crashes in iOS 16 beta

Expected Behavior

App should not crash and display Arabic text

Actual Behavior

App crashes in iOS 16 beta for the Arabic language where it working fine in iOS 15

### Workaround :

If we remove the ar from info.plist Localizations then it will not crash for new line

Thanks for the report! Would you maybe be able to put all this together on a small reproduction project that shows the issue? That will make sure that we don't miss anything here and can identify the crash properly. Thanks!

Is there any other potential workaround for those cases where you cannot remove arabic from info.plist ?

Sep 15 '22 11:09 bGiac

@RamyaBR Are you sure it is related to Arabic strings containing new line in the .resx files? I have those in my app and it worked fine on iOS 16 beta devices. However, two days ago appcenter started registering large number of crashes and all of them with iOS 16 with the exact error as yours "SIGABRT: NaN is not a valid value for width" , and I'm stuck not sure what could be the reason ..

@jfversluis as of today VS is not compatible with xcode 14 / iOS16 simulators https://github.com/xamarin/xamarin-macios/issues/15954 so it's impossible to debug and fix ... it's really frustrating that an app that works fine with iOS 15*, crashes on iOS16! not sure though if this is xamarin or apple's fault

Sep 16 '22 16:09 darrabam

Reference

yes In iOS 16 beta Xamarin-based applications are crashing if there is an ar entry like below in info.plist. The app would crash for all the new lines, it can be there in Arabic text or in if it there in the label like this
"
"

<key>CFBundleLocalizations</key>
	<array>
		<string>it</string>
		<string>de</string>
                 <string>ar</string>
       </array>

if you remove the entry from info.plist, the app will not crash and if you have App resources for Arabic it will automatically pick the Arabic language then it will work. Info.plist entries are required for the translation of system permission strings.

sure I will try to upload a sample app as soon as possible. currently, I am unavailable at the station.

Hi I confirm that the problem is on iOS 16. The problem seems to be with Label and Arabic info.plist, when you set a text on label that contains a new line. It doesn't matter if the text is written in Arabic or English

Steps to reproduces are very simple:

Create a Xamarin Forms projects and on MainPage add a Label <Label x:Name="lbTest" > </Label>
In MainPage constructor set the label text "A\nB"

public partial class MainPage : ContentPage
{
      public MainPage()
       {
                 InitializeComponent();
                 lbTest.Text = "A\nb";
        }
}

Add Arabic on Info.plist localization

      <key>CFBundleLocalizations</key>
	<array>
		<string>en</string>
		<string>ar</string>
	</array>

Set you iPhone with iOS 16 on arabic language.
Start the app. Crash

I hope this issue will be fix very soon because we have big problems with our apps.

The issue also happens in Hebrew and It's very odd that the same app works fine in English and crashes in Hebrew, only in iOS 16.

A temporary workaround may be creating a custom label renderer overriding GetDesiredSize to catch the exception.

The stack is:

Please update this issue title to show that the bug affects iOS 16 in production, not beta, in Arabic and Hebrew, and crashes when you have labels that include \n or \t.

Sep 20 '22 13:09 Jones-Abramoff

The crash also occurs for Persian language.

So it's RTL problem.

What about sharing temporary workarounds ?

Mine is this:

using UIKit;
using Xamarin.Forms;
using YourAppHere.iOS.Renderers;
using Xamarin.Forms.Platform.iOS;
using System;

[assembly: ExportRenderer(typeof(Label), typeof(CustomLabelRenderer))]

namespace YourAppHere.iOS.Renderers
{
    public class CustomLabelRenderer : LabelRenderer
    {
        public override SizeRequest GetDesiredSize(double widthConstraint, double heightConstraint)
        {
            try
            {
                return base.GetDesiredSize(widthConstraint, heightConstraint);
            }
            catch
            {
                if (Element == null || string.IsNullOrEmpty(Element.Text))
                {
                    return new SizeRequest();
                }
                if (Control != null)
                {
                    CoreGraphics.CGSize fitSize = Control.SizeThatFits(Element.Bounds.Size.ToSizeF());
                    return new SizeRequest(new Size(fitSize.Width, fitSize.Height), new Size(100, 20));
                }
                return new SizeRequest(new Size(Element.Text.Length*10,40), new Size(100, 20));
            }
        }
    }
}

                    CoreGraphics.CGSize fitSize = Control.SizeThatFits(Element.Bounds.Size.ToSizeF());
                    return new SizeRequest(new Size(fitSize.Width, fitSize.Height), new Size(100, 20));
                }
                return new SizeRequest(new Size(Element.Text.Length*10,40), new Size(100, 20));
            }
        }
    }
}

Thanks for sharing your workaround To make it work with FormatedText I change a line

public override SizeRequest GetDesiredSize(double widthConstraint, double heightConstraint)
       {
           try
           {
               return base.GetDesiredSize(widthConstraint, heightConstraint);
           }
           catch
           {
               if (Element == null || string.IsNullOrEmpty(Control?.Text))
               {
                   return new SizeRequest();
               }
               if (Control != null)
               {
                   CoreGraphics.CGSize fitSize = Control.SizeThatFits(Element.Bounds.Size.ToSizeF());
                   return new SizeRequest(new Size(fitSize.Width, fitSize.Height), new Size(100, 20));
               }
               return new SizeRequest(new Size(Element.Text.Length * 10, 40), new Size(100, 20));
           }
       }

I have the same problem as described above and have not been able to update my app since iOS 16 went live. The app crashes for everyone who relies on RTL languages. Please fix this error!

Have you tried the workaround above? It's working fine for me.

Xamarin has around 2.6k open issues. Do you really believe that they will choose this to fix?

Unfortunately, the workaround does not work for me with longer texts. I have several multiline labels. These are then no longer fully displayed, but only a part of the text.

Have you tried to increase the height for each \n or something similar just to see if the label is shown correctly?

Oct 15 '22 18:10 Jones-Abramoff

Hey everyone! A PR (#15605) for this is open now, would you be able to grab the NuGet as described here and let us know if this fixes this issue? That will greatly speed up the review process.

Besides verifying if this particular issue is fixed also be sure to check other scenarios in the same area to make sure that this fix doesn't accidentally has side-effects 🙂

Thanks!

Still having problems even with SR13, in 16.2 and 16.0.2 iOS. The app was created with Visual Studio for Mac 17.4.2 (build 17) and XCode 14.1. Try with a label with מספר נקודות גז ע"פ הצהרת הצרכןxxxx inside a stacklayout, where xxxx is a tab character.
