All developers have to make a decision when they start programming. Which Programming language to choose from. Which is the ultimate framework to build a plattform and bring it to a big variety of users.

Kotlin Multiplattform allows to create apps for Android, IOS,Web and Desktop. What are the pros and cons of this programming environment?

Pros	Cons
Effortless Simulator Testing: On IOS,Android, Web and Desktop.	Still requires Mac for iOS testing and deployment
Performance: Near-native performance with shared business logic	Platform-Specific Code: Still need native code for platform-specific features
Single Language: Use Kotlin for all platforms	Learning Curve: Requires understanding of multiple platform architectures
JetBrains Support: Strong backing from JetBrains with regular updates	Debugging Complexity: Cross-platform debugging can be more challenging
Gradual Adoption: Can be adopted incrementally in existing projects	Simultaneous testing: Running 4 simulators at the same time are not possible on my 6 year old mac.
