I do not know any Swift classes which returns the exact result as uname -m.
One possible way is calling the system function in Swift:

Code Block var systeminfo = utsname()
uname(&systeminfo)
let machine = withUnsafeBytes(of: &systeminfo.machine) {bufPtr->String in
    let data = Data(bufPtr)
    if let lastIndex = data.lastIndex(where: {$0 != 0}) {
        return String(data: data[0...lastIndex], encoding: .isoLatin1)!
    } else {
        return String(data: data, encoding: .isoLatin1)!
    }
}
print(machine)
