# Swift Function for Data Processing

```swift
func processData(inputData: [String: Any]) -> [String: Any] {
    guard let data = inputData as? [String: Any] else {
        print("Invalid data format")
        return [:]
    }

    // Process the data
    var processedData = [String: Any]()
    for (key, value) in data {
        if let stringValue = value as? String {
            processedData[key] = stringValue.uppercased()
        } else if let intValue = value as? Int {
            processedData[key] = intValue * 2
        }
    }

    return processedData
}
```

### Explanation
This Swift function processes input data by converting string values to uppercase and doubling integer values. It includes error handling to ensure the input data is in the correct format. The function can be integrated into an existing iOS app by calling it with the appropriate data dictionary.

### Integration Example
```swift
let inputData: [String: Any] = ["name": "john", "age": 25, "city": "new york"]
let processedData = processData(inputData: inputData)
print(processedData)
```

### Output
```
["name": "JOHN", "age": 50, "city": "NEW YORK"]
```
