  <p>I take that error when I want to use simulator. There is no problem when I build it on iPhone. There is only problem when I use simulator. I have tried to change Architectures from Build settings, error text changes as i386 but problem is same.</p>
  
  <p>I use that sdk; <a href="http://development.tzonedigital.cn/Beacon/IOS/SDK_v1.0_20160630.zip" rel="nofollow noreferrer">TZBeacon</a> </p>
  
  <p>Is there any problem with sdk? Could you help me to solve that problem?</p>
