Swift3: Combining two uint64 type options

What's the proper way to write this in Swift 3?

let ld = NSDataDetector(types: NSTextCheckingResult.CheckingType.address | NSTextCheckingResult.CheckingType.phoneNumber)

This is what I get:

Binary operator | cannot be applied to two NSTextCheckingResult.CheckingType operands.

I know they're both UInt64's, but I have no idea how to combine them.

I'd personally go with a functional approach, by using an array of CheckingType values. This will reduce the code duplication and makes it easy to add new check types to the scanner:

let detectorTypes = [
    NSTextCheckingResult.CheckingType.address,
    NSTextCheckingResult.CheckingType.phoneNumber
].reduce(0) { $0 | $1.rawValue }
let detector = try? NSDataDetector(types: detectorTypes)

Or, to further reduce the duplications in the values prefixes:

let types: [NSTextCheckingResult.CheckingType] = [.address, .phoneNumber]
let detector = try? NSDataDetector(types: types.reduce(0) { $0 | $1.rawValue })

Try this

do {
    let ld = try NSDataDetector(types: NSTextCheckingResult.CheckingType.address.rawValue | NSTextCheckingResult.CheckingType.phoneNumber.rawValue )
}
catch {

}

address in NSTextCheckingResult.CheckingType.address is a enum case, not UInt64. The raw value is UInt64, so you can use raw value like this, 

do{

let ld = try NSDataDetector(types: NSTextCheckingResult.CheckingType.address.rawValue | NSTextCheckingResult.CheckingType.phoneNumber.rawValue)

}catch{
    print("error")
}

Use the raw value of these constants as the type CheckingType is not an int variant:

NSDataDetector(types: NSTextCheckingResult.CheckingType.address.rawValue | NSTextCheckingResult.CheckingType.phoneNumber.rawValue)
