arkit

I'm trying to upload my app that uses ARKit (Unity build) to iTunes Connect for TestFlight distribution. While both exporting and uploading to app store processes from Xcode -> Organizer I see crash on "Stripping extended attributes for APPNAME.app". I checked all configuration of bitcode and symbols on/off, signing automatically, manually. Deployment target of my project is iOS 10, as 11 cannot be set. I also tried following steps from simillar thread ( https://forums.developer.apple.com/thread/83219 ) and added App Store 1024 icon to Images.xcassets. Any ideas why Xcode is crashing?

I'm trying to create a custom SCNGeometry in the form of a plane with custom shape, which could be placed in an ARKit session. I'm using the option SCNGeometryPrimitiveTypePolygon in the following method which seems to work fine: extension SCNGeometry { static func polygonPlane(vertices: [SCNVector3]) -> SCNGeometry { var indices: [Int32] = [Int32(vertices.count)] var index: Int32 = 0 for _ in vertices { indices.append(index) index += 1 } let vertexSource = SCNGeometrySource(vertices: vertices) let indexData = Data(bytes: indices, count: indices.count * MemoryLayout<Int32>.size) let element =

I'm trying to understand the difference between the different element introduced in ArKit and their maybe equivalents in SceneKit: SCNNode.simdTransform vs SCNNode.transform . In ARKit, it seems that people use SCNNode.simdTransform instead of SCNNode.transform . How do they differ? simdTransform seems to use column major order, while transform (SCNMatrix4) is row major. How do I convert one to the other? Just transpose? I've the impression that the tracking doesn't work as well if I use transform instead of simdTransform . Is that expected or just an impression? If I set one property, what

I am trying to create a framework that works with METAL Api (iOS). I am pretty new to this platform and I would like to know how to build the framework to work with .metal files (I am building a static lib, not dynamic). Should they be a part of the .a file, or as a resource files in the framework bundle? Or is there an other way to do that? Thanks. Update: For those who tackle this - I ended up following warrenm's 1's suggested option - converted the .metal file into a string and calling newLibraryWithSource:options:error: . Although it is not the best in performance it allowed me to ship

I have scanned and trained multiple real world objects. I do have the ARReferenceObject and the app detects them fine. The issue that I'm facing is when an object doest not have distinct , vibrant features it takes few seconds to return a detection result, which I can understand. Now, I want the app to show a bounding box and an activity indicator on top the object while it is trying to detect it. I do not see any information regarding this. Also, if there is any way to get the time when detection starts or the confidence percentage of the object being detected. Any help is appreciated. It is
