App Store Connect Operation Error Transporter Issue

I am trying to upload my app however I keep having this error pop up. I'm not sure what caused it as I didn't really change anything but I can't seem to fix it. It looks like a file is missing. I've tried reinstalling Xcode but that did not resolve anything. Any help is appreciated.
Okay, I found a fix. It was actually really simple. I just deleted the file /Library/Caches/com.apple.amp.itmstransporter and the files and all of its components were regenerated correctly when uploading to App Store Connect.

Swift Compiler Error Group

Sorry to post this again. But I really got lost in solving this bug in my Xcode. I am using Xcode Version 8.0 swift 3 , I have got this error when building the project:
Command failed due to signal: Segmentation fault: 11, and it shows me in the storyboards the code in black color for a while. Also, there is a notification says An internal error occurred, Source editor functionality is limited, attempting to restore, Report a Bug.
I have searched a lot and most things I found about building, cleaning, reopening the project. Also, I tried to uncheck and recheck the Automatically managed signing for my project.
I hope to hear from you the best solution for my problem
waiting for your replay greatest coders
I had this same issue. I went to the 'Debug Session' window and saw I had type conversion issues. I was trying to determine is an object was a Set and needed to evaluate it as a Set<String>.
Not sure if that'll help you, but check out the 'Debug Session' window to see which view controller class has the issue and what it is.

can't find blueprint in packaged unreal project

i'm working on a game in unreal, and just for funsies i decided to package my project to see how it would work outside the editor. for some reason it doesn't, its says fatal error followed by a bunch of error codes.
I tried going through the log, which can be found here: Link to download on Mega.nz
the log says it couldn't find the blueprint for my "BasicBullet", although the editor can (it both compiles and runs fine in the editor). That message is followed by somehting i don't understand, and then a fatal error message. can someone explain what is going on?
Thanks in advance
I fixed the problem, all i had to do was go to the config folder, in the project and edit the DefaultEditor.ini file.
i changed bDontLoadBlueprintOutsideEditor= true to bDontLoadBlueprintOutsideEditor= false and now it works perfectly.
been struggling with this problem for days now, and the solution was so simple.

Eclipse error log pops up after every save

Whenever I make any edits in eclipse (using STS) and save them the error log pops up. It's extremely annoying and I have no idea how to get rid of it. Anyone face a similar issue and how to resolve it?
