# maxOSLogArgumentCount

The maximum number of interpolated expressions that a log message may contain.

## Declaration

```swift
var maxOSLogArgumentCount: UInt8 { get }
```

## Discussion

Discussion For log messages that include interpolated values, the system imposes a limit on the total number of expressions that a single message may include. The following example shows a string that contains an interpolated value: let fileID = 941 let message = "Created a file with ID \(fileID)"
