When migrating to Swift 6 with strict concurrency mode enabled, you might encounter the warning 'Reference to captured var in concurrently-executing code'. This occurs when a mutable variable is captured in a body of code that runs asynchronously, leading to potential data inconsistencies. Solutions include changing the variable to a constant using `let`, making an explicit capture within closures, or shadowing the variable with a constant before asynchronous execution.
