# executableArchitectures

An array of numbers indicating the architecture types supported by the bundle’s executable.

## Declaration

```swift
var executableArchitectures: [NSNumber]? { get }
```

## Discussion

Discussion An array of NSNumber objects, each of which contains an integer value corresponding to a supported processor architecture. For a list of common architecture types, see the constants in Mach-O Architecture. If the bundle does not contain a Mach-O executable, this is nil. The bundle scans its Mach-O executable and returns all of the architecture types it finds. Because they are taken directly from the executable, the values may not always correspond to one of the well-known CPU types defined in Mach-O Architecture.
