fix(session-replay): Add exemption for CameraUI traversal for iOS 26.0

[philprime]

📜 Description

This pull request introduces a targeted workaround in the SentryUIRedactBuilder to handle a crash related to CameraUI.ChromeSwiftUIView on iOS 26 when built with Xcode 16. The workaround ensures that the redaction process skips subtrees of this specific internal camera view to prevent the crash, while maintaining normal redaction behavior for other views.

Camera view crash workaround (iOS 26, Xcode 16+):

• Added a runtime check in SentryUIRedactBuilder to detect and skip subtrees of CameraUI.ChromeSwiftUIView when running on iOS 26+ to prevent crashes from unimplemented initializers. (cameraSwiftUIViewClassObjectId, isViewSubtreeIgnored, redactRegionsFor(view:)) [1] [2] [3]

Redaction logic improvements:

• Updated redaction region naming to use view.debugDescription instead of layer.name for more consistent identification. [1] [2]

Unit tests for workaround and redaction:

• Added comprehensive tests to verify subtree skipping, normal redaction behavior, and that the workaround is only active under the correct conditions. [1] [2]

Camera UI integration (demo/sample):

• Modified ErrorsViewController.swift to present the camera UI using UIImagePickerController for testing camera permission flows.

‼️ THIS WILL BE REMOVED BEFORE THE PR IS MERGED

💡 Motivation and Context

Fixes #5647

💚 How did you test it?

• Added additional unit tests.
• Compiled the iOS-Swift sample using Xcode 16 and ran the app in iOS 26 Beta 7

📝 Checklist

You have to check all boxes before merging:

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

h: When looking at the crash in #5647 it could be that simply calling NSClassFromString could still lead to crashes. We had a weird issue in the past when swizzling UIViewControllers (#3798) and therefore we don't call it in the SentrySubClassFinder for excluded classes

sentry-cocoa/Sources/Sentry/SentrySubClassFinder.m

Lines 72 to 77 in 15a6325

	// It is vital to avoid calling NSClassFromString for the excluded classes because we
	// had crashes for specific classes when calling NSClassFromString, such as
	// https://github.com/getsentry/sentry-cocoa/issues/3798.
	if (shouldExcludeClassFromSwizzling) {
	continue;
	}

I even opened a bug in the Swift repo but it never got fixed: swiftlang/swift#72657. I'm unsure if it's worth the effort to do this right now. Simply doing a check if we're running on iOS 26 could be safer.

Using NSClassFromString will load the type into the Objective-C runtime and call it's +initialize() method, which could cause side-effects. Instead I will refactor it to convert the type of the current view and compare by their string name instead.
