Native and Cross Platform Trade Offs Questions

Evaluation of the architectural and technical trade offs when building mobile applications using native platform development versus cross platform frameworks. Includes when to choose native iOS and Android development using platform specific languages and toolchains versus cross platform frameworks such as React Native, Flutter, or Kotlin Multiplatform Mobile. Covers performance characteristics, startup and runtime speed, memory usage, and responsiveness; developer productivity and time to market through code sharing and single code base benefits; user experience and platform specific look and feel; access to platform specific features and native APIs; bridging and interoperability costs for native modules and plugins. Also covers testing and quality assurance implications, build and release pipelines, application size and update strategies, maintenance and long term technical debt, team skills and hiring considerations, ecosystem maturity and third party library support, security and platform compliance, and business considerations such as total cost of ownership and product roadmap trade offs.

Explain the core differences between native mobile development (Swift/Kotlin) and cross-platform frameworks (React Native/Flutter/Kotlin Multiplatform). Focus on runtime and compile-time performance, access to platform APIs, developer productivity, typical use cases, and quick guidance you would give a product manager choosing between them.
