Just follow those steps:
Open the this link: http://www.telerik.com/download/ios-ui
Click on the big red button named "Download Installer"
from the first attached image.
Use the downloaded package installer to install the latest version of Telerik UI for iOS. The installer title should contain "Telerik UI for iOS Q2 2015 Trial (v2015.2.624)"
- the same as on the attached image.
Replace all references to Telerik UI frameworks in your project with their latest versions.
If you still experience the issue, send us your project and we will try to locate the problem.
