Description
The
UIViewLayoutRegionAPI was included in earlier versions of the iOS 17 beta but has since been completely removed from the iOS 18 / Xcode 16 SDK.Currently, on the
mainbranch, the code attempts to disable this block by wrapping it inif (@available(iOS 26.0, *)). However, in C and Objective-C, the compiler tokenizes and type-checks the entire file regardless of runtime conditionals. SinceUIViewLayoutRegionis not declared anywhere in the iOS 18 headers, compiling this file on Xcode 16 throws a semantic compiler error:Use of undeclared identifier 'layoutRegion', which completely breaks any project depending on this CocoaPod (including those usingflutter_image_cropper).Solution
This PR resolves the compiler error by wrapping the disabled block in a proper preprocessor directive (
#if __IPHONE_OS_VERSION_MAX_ALLOWED < 180000). This ensures that the Xcode 16 compiler completely ignores the undeclared identifier during the build step, while preserving the behavior for older SDKs.This is a critical fix required for any project migrating to macOS-15 and Xcode 16.
