Sep 1, 2025

September 2025 monthly summary for unoplatform development focused on strengthening dependency discipline, improving iOS development workflows, and hardening install-time security across two core repos. In unoplatform/uno, centralized Uno.Resizetizer versioning to 1.11.0-dev.17 by moving the version definition to Directory.Build.props and removing explicit PackageReference updates from Directory.Build.targets, ensuring consistent versions and enabling the latest fixes across templates. In unoplatform/uno.check, delivered improvements to the iOS SDK workflow: enhanced validation that reports both validity and the specific SDK version, clearer error messaging for missing SDKs, and tailored download commands to streamline setup; plus a security fix that uses a unique temporary directory for iOS SDK runtime installations to prevent code injection. These changes reduce setup friction, improve build reliability, and fortify the development environment, delivering measurable business value through more reproducible builds and faster onboarding. Technologies and skills demonstrated include MSBuild and Directory.Build.props/targets usage, NuGet version management, iOS/Xcode tooling, CI pipeline stabilization, and secure installation practices.
