Thanks @hollance for his useful CoreMLHelpers.

Vision

• Face detection. Detects all faces on selected photo.

• Face landmarks. An image analysis that finds facial features (such as the eyes and mouth) in an image.

• Object tracking. Track any object using camera.

ARKit

Augmented reality experiences in your app or game.

Drag and Drop

Easy way to move content.

Core NFC

Reading of NFC tag payloads. Don't forget to enable NFC Tag Reading for App ID in the Apple Developer site.

Note: select CoreNFC-Example scheme and run.

MapKit

New map type, new anotation views and clustering!

IdentityLookup

SMS and MMS filtering using IdentityLookup framework. Don't forget to turn on an extension in Messages > Unknown & Spam > SMS filtering.

DeviceCheck

Identifying devices that have already taken advantage of a promotional offer that you provide, or flagging a device that you have determined to be fraudulent.

How CoreML is working in the sample?

I am seeing "Inceptionv3.mlmodel" file inside the "CoreML" group. I am sure that the answers are coming from that 91mb mlmodel file.

Few questions:

1. Where did you get this file?
2. Is this the dependency for this task? I mean, if we don't have this file, we couldn't do this?
3. Why we need CoreML framework to work with this file?

P.S. Here this file means, mlmodel file.

Do anyone has the Sample Code for "Handling 3D Interaction and UI Controls in Augmented Reality"

Apple published the "Handling 3D Interaction and UI Controls in Augmented Reality" sample code.
but this is for BETA iOS 11.3.

Do anyone has the previous 11.2 version ? I dont want to develop for 11.3 I want to develop to current latest public iOS version.

Screen capture example

Hi! Do you have any screen capture example? I used to use this code (mixed with some Javascript/Nativescript) but, for some reason, it is not working anymore after updating to iOS11. I belive this is related to the new behavior of a screenshot (which now shows the captured image for a few seconds, before saving or opening it for editing):

UIGraphicsBeginImageContextWithOptions(view.ios.frame.size, false, 0);
view.ios.drawViewHierarchyInRectAfterScreenUpdates(CGRectMake(0, 0, view.ios.frame.size.width, view.ios.frame.size.height), true);
var imageFromCurrentImageContext = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return imageSource.fromData(UIImagePNGRepresentation(imageFromCurrentImageContext));

Why a paid apple developer account is must?

To run this project, we should provide our own Apple Developer paid Account. Now, this should not be a constraint. I am not having an Apple account, what should I do run it? Generally, I should able to install an app in my iPhone with my Apple ID which is not linked to paid membership.

New Core Image Filters

Could you add examples of the new Core Image filters?
CITextImageGenerator, CIColorCurves, CILabDeltaE, CIBokehBlur, CIMinMaxRed and CIBicubicScaleTransform.

OpenGL

Hello, what version of OpenGL does iOS 11 support?
Do you have any examples using OpenGL on iOS 11?

Swift Code Error

Image Not Valid Size for CoreML

I try to run the app and I get this error

{Error Domain=com.apple.CoreML Code=1 "Image is not valid width 299, instead is 449" UserInfo={NSLocalizedDescription=Image is not valid width 299, instead is 449}}}

I see in the UIImage+Processing.swift that you resize the image to 149.5 rather than the model input size, which is 299. I am testing on an iPhone6SPlus, so I am not sure if screen size is an issue.

Any help or advice on how to trouble shoot would be great!

Error code in MessageFilterExtension.swift

Hi there!

There is an error in line 48 of the MessageFilterExtension.swift file... For some reason that I do not figure out yet, I can't submit a pull request, so here is the line to fix:

let messageBody = queryRequest.messageBody ?? "No body"

Thanks for sharing this code, help me a lot!! ;-)

App doesn't work on iPad

Probably intended, and not a huge issue, but there's probably a way to not require NFC and the rest would work on iPad?

I could and should dive in myself, but may not have time, so just leaving this here. Feel free to close/reject if it's not a priority.

No such module 'DeviceCheck'

I run the project and Xcode say this.
