ios - Both iPhone cameras on the same view? -

-

i've had around online, , had play around myself have been unable find literally on topic, assume it's never been played around before. 

let devices = avcapturedevice.devices().filter{ $0.hasmediatype(avmediatypevideo) && $0.position == avcapturedeviceposition.back }     if let capturedevice = devices.first as? avcapturedevice  {           {             try sessioncap.addinput(avcapturedeviceinput(device: capturedevice))         } catch {          }          sessioncap.sessionpreset = avcapturesessionpresetphoto         sessioncap.startrunning()          stillimageoutput.outputsettings = [avvideocodeckey:avvideocodecjpeg]          if sessioncap.canaddoutput(stillimageoutput) {             sessioncap.addoutput(stillimageoutput)         }          if let previewlayer = avcapturevideopreviewlayer(session: sessioncap) {              previewlayer.bounds = view.bounds             previewlayer.position = cgpointmake(view.bounds.midx, view.bounds.midy)             previewlayer.videogravity = avlayervideogravityresizeaspectfill              let camerapreview = uiview(frame: cgrectmake(0.0, 0.0, view.bounds.size.width, view.bounds.size.height))              camerapreview.layer.addsublayer(previewlayer)             camerapreview.addgesturerecognizer(uitapgesturerecognizer(target: self, action:#selector(viewcontroller.savetocamera(_:))))              view.addsubview(camerapreview)         }     }

so code have @ moment, it shows iphone facing camera on viewcontroller, , have other code takes allows user take picture - great. however, wondering how possible add both cameras on same view?

screen view example

the black area front facing camera ("selfie camera"), , cyan area facing camera. i'm going continue looking while posted here, feel it's lost cause.

it seems me impossible.

you cannot use both cameras @ same time, not allowed simultaneously. 1 avcapturesession begins, other avcapturesession stop because requires device hardware.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
