[WebView] Crash on iOS [UIColor colorWithSRGBRed:green:blue:alpha:]: unrecognized selector sent to class

### Bug: Crash on iOS — `+[UIColor colorWithSRGBRed:green:blue:alpha:]: unrecognized selector sent to class`

**Date:** 2025-11-03
**Platform:** iOS Simulator 26.0 (Xcode 16, .NET 8.0, Avalonia iOS)
**Project:** `Cv.Application.iOS`

---

#### 📋 Description

The application crashes on startup in the iOS with the following error:

```
Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: '+[UIColor colorWithSRGBRed:green:blue:alpha:]: unrecognized selector sent to class'
```

The crash occurs during the initialization of `Avalonia.Controls.NativeWebView`, when attempting to call `UIColor.colorWithSRGBRed:green:blue:alpha:`.
It appears Avalonia is invoking the newer API `UIColor(colorWithSRGBRed:green:blue:alpha:)`, which may be unavailable in the current iOS SDK or incorrectly bound via Xamarin.

* **iOS SDK:** `26.0`
* **Simulator:** iPhone 15 Pro (`9E682080-816E-46BB-B0C7-0DDA63EC0780`)
* **Xcode:** `/Applications/Xcode.app (16.0)`
* **Avalonia:** 11.3.8 (iOS backend)
* **Avalonia.Controls.WebView** 11.3.14
* **Target Framework:** `net8.0-ios`

#### 💡 Hypothesis

The static method `+[UIColor colorWithSRGBRed:green:blue:alpha:]` was introduced in iOS 13, but may be unavailable in certain simulator environments or when using older Objective-C runtime bindings.
Avalonia may be incorrectly calling a **static selector** when UIKit expects an **instance initializer** such as:

```objc
[[UIColor alloc] initWithSRGBRed:green:blue:alpha:]
```

or

```objc
[UIColor colorWithRed:green:blue:alpha:]
```
