chore: [SDK-5280] raise minimum iOS version to 15 - #26
Merged

Conversation
Xcode 27 rejects deployment targets below iOS 15 and the OneSignal iOS SDK that consumes this framework is moving to a 15 minimum. All three iOS slices now carry a 15.0 minimum, which the linker records as LC_BUILD_VERSION, so the verification task expects that load command for the device and x86_64 simulator slices instead of LC_VERSION_MIN_IPHONEOS. Catalyst stays at 14.

Summary
Raise the iOS minimum of the packaged XCFramework from 11 to 15. The Kotlin/Native minimum-version overrides, the Mach-O verification expectations,
OneSignalKMP.podspec,Package.swiftand the README all move to 15.0. Catalyst stays at 14.Motivation
Xcode 27 rejects deployment targets below iOS 15 and the OneSignal iOS SDK that consumes this framework is moving to a 15 minimum (OneSignal/OneSignal-iOS-SDK#1749). At 15.0 the linker records the minimum as
LC_BUILD_VERSIONon every slice, so the device and x86_64 simulator expectations switch fromLC_VERSION_MIN_IPHONEOSto platform and minos checks like the arm64 simulator slice already used.Testing
./gradlew :kmp:verifyOneSignalKMPXCFrameworkpasses locally on Xcode 27: every iOS slice now carriesLC_BUILD_VERSIONwith minos 15.0 and the Catalyst slices stay at 14.0.Checklist
