I'm facing same problem. Using xcode 8.3.2 and swift 3 and Unity3D 5.6.0f3

Hi,

Are you sure you included all the frameworks ? I got stuck with the same problem for one week and I realized I missed 1 framework when I opened the Xcode project Unity gives and compared its libraries and mine.
Here are the frameworks I'm using :
AssetsLibrary
AudioToolbox
AVFoundation
CFNetwork
CoreGraphics
CoreLocation
CoreMedia
CoreMotion
CoreVideo
Foundation
iAd
libiconv.2.tdb
MediaPlayer
MediaToolBox (this was the missing one)
OpenAL
OpenGLES
QuartzCore
Security
SystemConfiguration
UIKit
libiPhone-lib.a
libVuforia.a*
libVuforiaUnityPlayer.a*

*only if you use Vuforia in your scene

Hi, I'm not using Vuforia. I've found what was the problem. I had to rollback to older version (5.3.8f1) of unity editor. If the unity app is build with newer version it throws same or similar errors. I'm hoping Unity will fix this because It's quite incovenient.

That's strange, I'm using Unity 5.6.0f3 and I was able to solve the problem as I described before.

If I were to make a guess, I'd say with newer version of Unity you need to make sure you use all the frameworks I mentioned (especially not forget the MediaToolbox.framework) in Build Phases -> Link Binaries with Libraries. Using Vuforia or not doesn't matter because the problem doesn't come from it.

Ok, I can give it try next time I will deal with this. Thanks for help !

I solved it by adding in Unity.xcconfig:

OTHER_LDFLAGS = [...] -framework MediaToolbox [...]
