What is the difference between safe and unsafe modes of code execution or operations?

Safe mode for executing code or operations implies that the system or runtime environment applies additional checks and restrictions to prevent errors, failures, or malicious actions. In this mode, operations are performed with access control, type checking, exception handling, etc.

Unsafe mode usually means executing code without such checks, which can increase performance but also raises the risk of errors, failures, or vulnerabilities.

For example, in iOS, safe mode may restrict access to certain resources or run code in a sandbox, whereas unsafe mode may allow more direct access to system functions but requires greater caution.
