Is it possible to determine whether a closure will be escaping based on the use of a third-party library in the project?

It is not possible to determine whether a closure is escaping solely based on the use of a third-party library. It depends on how the library uses the passed closure.
An escaping closure is one that can be called after the function it was passed to has finished executing. If the library stores the closure for later invocation (for example, asynchronously), then it is escaping.
To understand whether a closure is escaping, you should:
- Review the library's documentation — it usually indicates which closures are escaping.
- Check the function or method signature where the closure is passed (in Swift, escaping closures are marked with the
@escapingkeyword). - If the source code of the library is available, verify whether it stores the closure for later invocation.
Without this information, it is impossible to determine whether a closure is escaping solely based on the usage of the library.
