    I have the same problem,I solve this problem through the following steps:

    • go to Targets-General-Frameworks,Libraries,and Embeded Content
    • Find the frameworks that are set to embed & sign
    • Show in Finder of this Framework
    • in Terminal run file xxx.framework(cd /XXX/XXX/thirdSDK.framework)
    • if you see current ar archive，Indicates that this is a static library。(if you see shared Library，Indicates that this is a dynamic library.)
    • if this framework is current ar archive,just need to set embed & sign to Don's signing。Then everything will be ok.
