# CallStackFrame

A single frame within a call stack thread.

## Declaration

```swift
struct CallStackFrame
```

## Mentioned in

Analyzing app performance with MetricKit

## Discussion

Discussion Each frame may have sub-frames that form a call tree. The binaryUUID references binary metadata in the parent binaryInfo dictionary. Use binaryName(from:) to look up the binary name for a given frame: if let name = frame.binaryName(from: tree) {     print(name) }
