I am not sure if this goes in Bug Reports… Fuse 0.35, Mac Sierra Anyway, so I just installed Fuse in a new Mac and everytime I try to build (even an empty project) to iPhone I get the following error ```auto dyld: Library not loaded: @rpath/Jetfire.framework/Jetfire Referenced from: /var/containers/Bundle/Application/5DDF148C-D276-4DDC-977F-8FC95B52FD31/test.app/test Reason: no suitable image found.

Hi, i have same issue … but this your solution don’t helped me ☹ I have do this steps: > Click on Product → Clean (or CMD-Shift-K) Or by manually cleaning the Xcode setting files: ```auto rm -rf "$(getconf DARWIN_USER_CACHE_DIR)/org.llvm.clang/ModuleCache" rm -rf ~/Library/Developer/Xcode/DerivedData rm -rf ~/Library/Caches/com.apple.dt.Xcode ``` I have also completely reinstall Fusetools … but still the same issue ☹ I use now 0.36 (build 11565) And it was builded with this command: ```auto fuse build --force -v -adebug --target=iOS --run ``` ![file](https://canada1.discourse-cdn.com/flex035/uploads/fusetools1/original/2X/7/7844033825ea2b2db957f47f8ff6017de33a08ec.png) ---

have you tried `uno clean`? If so, then perhaps upload the project so Fuse can see what’s wrong with it. Although, since .36 is not official yet I don’t know if they will be able to help (yet) ---

Yes i have tried also uno clean. But what i find out now is, that application working correctly in iPhone Simulator and application run in simulator without issue. But when i try it on my iPhone … then i get on start of my app occurs this error: ```auto dyld: Library not loaded: @rpath/Jetfire.framework/Jetfire Referenced from: /var/containers/Bundle/Application/801B553B-2A35-46D3-873C-A5D6DF3FE4B0/my.app/my Reason: no suitable image found.

I tried it on 2 different iPhone (iPhone 6 and iPhone 5C). The result is still same. ![file](https://s3.us-east-2.amazonaws.com/fuse-legacy-forum-assets/09ffYCq7pEE3-image-1490629586611.44.49.png) ---

I have exactly the same issue… Works fine on simulator but crash on device while trying to load Jetfire lib (it seems to be). I’m using XCode Version 8.3.2 (8E2002) on MacOS 10.12.4 (16E195). I’ve created a tiny and empty project using FuseDashboard. Thank you for your Help. ---

Solution: The certificate “Apple Worldwide Developer Relations Certification Authority” was set to “Always Trust” in the keychain. I had to set it back to “Use System Default” in order to make this work. - Select Keychain “System” - Select Category “Certificates” - Then select certificate “Apple Worldwide Developer Relations Certification Authority” -\> Get Info -\> Trust -\> When using this certificate: “Use System Default”
