Converting Objective-C to Swift Code

Question

NSDictionary *detectorOptions = [[NSDictionary alloc] initWithObjectsAndKeys:CIDetectorAccuracyLow, CIDetectorAccuracy, nil];

self.faceDetector = [CIDetector detectorOfType:CIDetectorTypeFace context:nil options:detectorOptions];

Please help me to convert this into swift.

I referred this code from iCapps. I have only learned Swift. I tried to understated the code, but its bit confusing. Please help me if any experts knows. And suggest me some ideas to convert Obj-C to Swift easily.

Answer 1

let detectorOptions = [CIDetectorAccuracy: CIDetectorAccuracyLow]
self.faceDetector = CIDetector(ofType: CIDetectorTypeFace, context: nil, options: detectorOptions)

Answer 2

Swift Code:

var detectorOptions: [NSObject : AnyObject] = [
    CIDetectorAccuracy : CIDetectorAccuracyLow
]

self.faceDetector = CIDetector.detectorOfType(CIDetectorTypeFace, context: nil, options: detectorOptions)

Answer 3

I have converted it for you, but now onwards use this site https://objectivec2swift.com for conversion if you don't know swift

var detectorOptions: [NSObject : AnyObject] = [
    CIDetectorAccuracy : CIDetectorAccuracyLow
]
self.faceDetector = CIDetector.detectorOfType(CIDetectorTypeFace, context: nil, options: detectorOptions)
